| CNS/PNS | What does the NS consist of? |
| Consists of brain and spinal cord. It is the origin of all decisions and commands. | CENTRAL NERVOUS SYSTEM |
| Sends info to CNS from outside world and transmits messages from CNS to glands/muscles. | PERIPHERAL NERVOUS SYSTEM |
| Transmits information from receptor cells in sense organs to CNS and receives info from CNS that directs muscles to act | SOMATIC NERVOUS SYSTEM |
| Divided into parasympathetic and sympathetic. Transmits info to and from organs | AUTONOMIC NERVOUS SYSTEM |
| Calms the body by decreasing heart and breathing rate, constricting pupils | PARASYMPATHETIC NERVOUS SYSTEM |
| Prepares the body for fight or flight response | SYMPATHETIC NERVOUS SYSTEM |
| Instructs glands to release hormones directly into the bloodstream and these are carried to target organs | ENDOCRINE SYSTEM |
| In large quantities | How are hormones produced? |
| Also known as master gland. Secretes hormones which stimulates other glands to secrete further hormones. | PITUITARY GLAND |
| Relay info between the brain and the body to regulate body processes such as breathing and digestion | What is the role of the spinal cord? |
| Brain and spinal cord | What does the CNS consist of? |
| Parasympathetic and sympathetic | What is the autonomic nervous system divided into? |
| Bloodstream | Where are hormones released into? |
| Stimulatating/controlling hormone release from the pituitary gland. Hypothalamus is the control system which regulates endocrine system | WHAT IS THE HYPOTHALAMUS RESPONSIBLE FOR? |
| Process where nerve impulse passes across synaptic cleft from one neurone to another | SYNAPTIC TRANSMISSION |
| Them substances playing role in NS function by transmitting nerve impulses across synapse | NEUROTRANSMITTERS |
| To carry messages across the body | WHY DO SENSORY NEURONES HAVE LONGER DENDRITES? |
| Relay messages between sensory and motor neurones | RELAY NEURONS |
| Segments the axon to speed up the electrical impulse by forcing it to jump across gaps in axon | NODES OF RANVIER |
| Excitatory and Inhibitory | WHAT ARE THE TYPES OF NEUROTRANSMITTER? |
| Send switch on signal to post synaptic neuron to ensure more positive charge and neuron likely to fire and send electric impulse | Excitatory Neurotransmitters |
| Sends switch off signals so more negative charge and less likely to fire and send electric signal | INHIBITORY NEUROTRANSMITTERS |
| Both inhibitory and excitatory potential | WHAT CAN A NERVE CELL RECIEVE? |
| Sum up the excitatory and inhibitory input, if mostly excitatory then likely so, if not less likely | HOW DO YOU DETERMINE THE LIKELIHOOD OF A NEURON FIRING? |
| Dopamine | EXAMPLE OF EXCITATORY NEUROTRANSMITTER |
| Serotonin | EXAMPLE OF INHIBITORY NEUROTRANSMITTER |
