Talk about the smooth muscle cells.

Smooth muscle cells (or fibers) are elongated fusiform (spindle-shaped) cells of variable size, depending on their localization. Each fiber contains only one centrally located ovoid nucleus containing one or 2 nucleoli. The sarcoplasm is acidophilic and low in myoglobin content. It presents two regions: one region where the major cell organelles are confined (Golgi, REG, mitochondria) at the 2 poles of the nucleus, and the other region (the peripheral cytoplasm) which is occupied by myofilaments which organization is different from that of the SSMC filaments and that do not form sarcomeres.
