Nervous Tissue; senses, conducts and processes information. | Tissues
Four Major Tissues and Subtypes
(Evan can make Nachos) |
Tissues differ in the amount and kind of fluid material between cells
Matrix= extracellular matrix
It varies in amount and composition amount the various
Jelly-like; made up mostly mate with various interlocking fibres.
Epithelial tissue have verylittlemzatrix because cells are so closely connected | Matrix=ECM |
Covers the body and man of its parts.
line various parts of the body
placed close together with little or no intercellular material between them. | Epithelial Tissue |
Squamous: flat and scale like (beer can flattened down)
Cuboidal: cube shaped
Columnar: higher than they are wide
Transitional: Varying shapes that can stretch
(Sometimes Chris can Try) | Epithelial Tissue
Shape identified: |
Simple: SINGLE layer of SAME shape
Stratified: MANY layers of cells | Epithelial Tissue
Categorized by cell arrangement classified as: |

is SINGLE layer of cells that are on average about as high as they are wide. | Simple Cuboidal epithelium |
consists of SEVERAL layers closely paced cells.
Common type of cancer in any organ
They protect the body against invasions by microorganisms | Stratified Squamous Epithelium |
Is a single layer of cells that are, on average about as high as they are wide.
This does not form protective coverings but instead form tubules or other groupings | Simple Cuboidal
Epithelium |
can be found lining the inner surface of the stomach, intestines and some ares of respiratory and reproductive tracts
"open spaces" among the cells are the goblet that produce mucus | Simple Columnar
Epithelium |
typical of that which line the trachea or windpipe
note that the epithelium in this figure appears to be several cell layers thick, ut it is not-hence is called Pseudo(false) stratified | Pseudos Stratified
Epithelium |
Stratified transitional Epithelium is typically found in the body areas subject to stress and must be able to stretch | Trasitional Epithelium |
connects tissues to each other and form a supporting framework for the body as a whole and for its individuals organs
Most abundant and widely distributed tissue in body. with many different types, appearances and functions
Four in skin, membranes, muscles, bones, nerve and internal organs
Relatively few cells in intercellular matrix | Connective Tissue |
Areolar: (loose connective) tissue: Fibrous glue(fascia)that hold organs together; collagenous and elastic fibres, plus a variety of cell types.
Adipose(fat) tissue: Lipid storage, metabolism regulation; brown fat prods heat.
Reticlular tissue: Delicate net of collage finer, as in bone marrow
Dense fibrous tissue:
Bundles of strong collagen fibres: ex: tendon
Bone tissue: Matrix is calcified; functions as support and protection
Cartilage tissue: Matrix is consistency of gristle-like gel; chondrocyte is cell type.
Blood tissue: Matrix is fluid; functions are transportation and protection. | Connective Tissue Types: |

Is the most widely distributed of all connective tissue types. Web of fibre.
Also called Areolar, consists of webs of fibres and a variety of cells embedded in a loose matrix | Loose Fibrous(Areolar) Connective Tissue |
When it begins to store lipids, areolar tissue can develop into adipose tissue, or fat tissue | Adipose Tissue:fat |

function to provide rapid communication between body structures and control of body functions.
Two types of cells:
Nerve cells(neutrons) cell body.
Two types of processes :
One Axon
one or more dendrites
special connecting and supporting cells(gila or neuralgic)
display characteristic cell bodies and multiple cell processes. Nuclei of glia are visible as dark dots surrounding the neutron. | Nervous Tissue |
A cell usually has three distinct areas or layers
*Membrane
*Cytoplasm & Organelles
*Nucleus | Cell Structure and Function
Three parts of a cell( My Chris is on Nights) |
protective covering allows materials into and out of the cell=selectively permeable.
Composed of lipids and proteins(act as a channel)
Double layer phospholipids=phospholipid bilayer
Prevents hydrophilic molecules to from passing | Cell Membrane |
Movement of substances into and out of the cell | Membrane Transport |
Passive Transport: no energy required.
cell doesn't use energy.
1. Diffusion
2. Faciliated Diffusion
3. Osmosis
Active Transport: cell must provide metabolic energy
Does used energy
1. Protein pumps 2. Endocytosis 3. Exocytosis | Two basic Transport Methods: |
chemicals outside a cell become concentrate moving into the cell , changing the intracellular equilibrium
High to low=with concentration on gradient.
Factors that affect diffusion
1. Temperature
2.Mass of Molecule
3.Solubility | Passive Transport |
Spontaneous passage of molecules or ions across a biological membrane. passing though specific transmembrane integral proteins
proteins can change in shape to accommodate the size of the molecules. | Facililated Diffusion |
net movement of water from a region of high concentration to a region of low concentration through a partially permeable membrane | Osmosis: |
Movement of materials through the cell membrane using energy
move from low concentration to high concentration.
Protein pumps
protein us ATP to pump "ions"
and small molecules against
concentration gradient. | Active Transport |
capturing a substance/ particle from outside the cell by engulfing it with the cell membrane and bringing it into the cell.
vesicles fussing with plasma membrane and releasing their contents to the outside of the cell | Active Transport
Endocytosis: moving in (EN=IN)
Exocytosis: moving out (EX= out exit) |
portion of cell between membrane and nucleus

Function:
gives cell shape
provides support for cell
provides anchorage for many organelles
allows movement of vesicles and some other along protein"highways"or monorails"
helps change shape
Involves types of whole cell motility city fagella | Cyto skeleton |
Microtubules -provides strength and function in moment of organelles. DNA (chromosomes) and Cilla and flagella provides some anchorage
Microfilaments- support cells shape by resisting pulling forces with the celll when cell contracts and relaxes
Intermediate Filaments- provide strength anchorage for organelles , movement of distance with cell and play a role in (cell to cell adhesion) | 3 Main Components of
Cytoskeleton |
Nucleus . Surrounded by a double wall nuclear but has large pores to a low certain material to go in. Controls centre of cell , the brain cell. Contains chromatin contains DNA
*Nucleolus
*within Nucleus
*synthesizes form ribosomes Ran | Organelles: |
consists of many interconnected sacs(cistern) into which ribosomes attached. Responsible for production of protein. Sends protein to Golgi
SER Reticulum consists of interconnected sacs that synthesizes lipids and steroids. | Organelles
Rough Endoplasmic Reticulum(RER)
Smooth Endoplasmic Reticulum(SER |
Apparatus(GA)
* flattened sacs
*Received proteins from RER processes it and make it shippable(vesicle)
AKA (As know as) the "POST OFFICE)
cells with a higher level of secretion contains more GA(salvia gland and pancreatic glands) | Golgi apparatus |
small round organelles found in the cytoplasm; formed from the "BUDDING OFF" of membrane from the ER the Golgi apparatus and or the plasma membrane.
* can be transport vesicles or secretory vesicles.
very large round organelles usually formed from the merging of many vesicles. | Vesicles:
Vacuoles: |
contains powerful hydrolytic enzymes that take care of cleaning up the intracellular debris and other waste.
*aid in maintaining health by destroying unwanted bacteria(phagocytosis)
Found in RER or floating freeing in cytoplasm
*assist in production of enzymes and other protein needed for cell repair and reproduction. | Lysomomes:
Ribosomes: |
contains centrioles which are involved in cell division.
(as know as )='POWER PLANT"provides 95%of the body's energy needs for cellular repair, movement and reproduction.
*Makes ATP have own DNA mtDNA | Centrosomes:
Mitochordria: |
assembled in the nucleolus , then exported out through the nuclear pores
*ribosomal(RNA)( rRNA) one of the macromolecules required for the synthesis of ribosomes is, manufactured in the nucleolus as well.
*Function: carries out protein synthesis in two locations:
In the cytosol-for proteins that will stay in the cell, these specific ribosomes are called "FREE RIBOSOMES"
*attaches to the outside of the RER or the nuclear envelope for proteins destined for the plasma membrane or outside the cell, these are "BOUND RIBOSOMES"
*location of the ribosomes is temporary-ribosomes move from free state to a "bound state or vie versa depending on the protein that is being made. | Ribosomes Protein Factories |
type of cell division results in two daughter cells each having the same number and kind of chromosomes as the parents nucleus (diploid clone) | Mitosis |
cells may appear inactive during this stage, but they are quite active
longest period of the complete cell cycle during which DNA replicates the centrites divide and protein are actively produced.
Prophase- First mitotic stage*nuceolous fades and chromatin(replicated DNA and associated proteins) condenses into chromosomes.
each replicated chromosome comprises two chromatids both with the same genetic info. Micro bulls of cytoskeleton, responsible for cell shape . Motility interphase disassemble . Building blocks of these microtubules are used to grow the mitotic spindle from the region of the centrosomes.
Metaphase: tension applied by the spindle fibres aligns all chromosome in one plane at the centre of the cell.
Anaphase: spindle fiber shorten the kinetocones separate and the chromatids(daughter chromes) are pulled apart and begin moving to the cell poles. | Mitosis
Interphase:
Prophase:
Metaphase:
Anaphase: |
Telophase-the daughter chromosomes arrive at the pole and spindle fibres that have pulled them apart disappear.
spltting cells
*the spindle fibres not attached to chromosomes begin breaking down until only that portion of overlap is left.
*in this region, contractile ring cleaves the cell into two daughter cells.
*mircrotubles then reorganized into two cytoskeleton for return to interphase
Mitosis(Khan Academy) I picked my today Charlie. | Mitosis
Telophase:
Cytokinesis: |
special type of cell division used by sexual reproducing organisms to produce the games, such as sperm or egg cell.
Involes two rounds of division that ultimately result in four cells with one one copy of each chromosome(haploid)
Additionally prior to division , genetic material from the paternal and material . copies of each from the paternal and material copies of each chromosomes is crossed over creating new combinations of code of each chromosome.
Later during fertilization, haploid cells produce meiosis from male to female fuse to create a cell with two copies of chromosome again "ZYGOTE" | Meiosis |
two distant division Meiosis. Meiosis 1 and Meiosis 11
Meiosis1 is responsible for genetic diversity.
Meiosis 2 reduced the amount of DNA in the daughter cells.
end of Meiosis 2 reduces the amount of DNS in the daughter cells.
At the end of Meiosis 2 each daughter cell has 23 chromosomes.
*Meiosis 1 and Meiosis 11 both have 4 stages: PROPHASE, METAPHASE, ANAPHASE and TELOPHASE. | Meiosis Stages: |
Cellular Changes:as the cell ages the plasma membrane has an increase amount of fatty acids. This structural change decreases the fluidity of the plasma membrane and reduces the transportation of the ions, nutrients, amino acids, and proteins across the membrane.
Nuclear changes-as cell ages cross linkages form between the sulphur atoms on the DNA in the nucleus of the cells . This structural change condenses the DNA which decreases the synthesis of RNA reduces the cell ability to repair enzymes and may reduce cell's ability to divide.
Cytoplasmic Change- as the cell ages the volume of cytoplasm increase enzymes that synthesize DNA move from the nucleus to the cytoplasm and there is a gradual build of lipofuscin.
While its unclear how this directly affects the cell it is know that once the DNA migrate from the nucleus it is unable to synthesizes enzymes.
Ribosomal Changes: the cell ages the amount of ribosomal decreases.
this structural change results in a decreased level of protein synthesis | Cellular changes during Aging
Cellular Plasma Membrane Changes;
Nuclear Changes:
Cytoplasmic Changes:
Ribosomal Changes: next page |
As the cell ages the number of mitochondrial present in a cell decreases. This structural change reduces the cell's ability to produce energy.
As the cell ages the lysosomes become less able to break down wast proteins, nucleic acids, carbohydrates and fats. Result is a build up waste within the cell. | Cellular changes during Aging
Mitochondrial changes:
Lysomal changes |
During cell developmental years the addition of cells helps tissue and organs grow .
in adults mitosis replaces cells that have become less functional with age or have been damaged or destroyed by illness or injury.
Many cells loose their ability to function worthy being to function abnormally.
If body cell loses its ability to control mitosis , an abnormal mass of proliferating cells develops -Neoplasm
Neoplasms that are harmless=BENIGN TUMOR(Evan)
Neoplasms there cancerous= MALIGNANT TUMOR. | Cell Division and Aging |
GI SYSTEM
Digestive tract(gastrointestinal tract) is described as Tube that extends from mouth to anus. | DIGESTIVE SYSTEM |
performs FOUR MAIN FUNCTIONS
Ingestion-nutrient into body
Digestion-Break down into particles
Absorption-take what we need
Elimination-get rid of what we don't need. | Digestive or gastrointestinal system |
food materials taken into mouth
food is broken down, mechanically(chewing, stomach grinding) and chemically(acids, enzymes) as it travels through the gastroiestinal tract.
Digestive enzymes aid the breakdown of complex nutrients
*protein-amino acids
*sugars-glucose
*Fats-fatty acids or triglycerides | Ingestion
and
Digestion |
digested food passes into the bloodstream absorbed through lining cells of the small intestine via VILLI
Nutrients travel to all cells of the body.
Cells burn nutrients to release the energy stored in food | Absorption |
the body eliminates solid waste materials that cannot be absorbed into the bloodstream.
The large intestine concentrates feces(POOP)
