Skeletal (or striated) muscle consists of muscle fibers, which are long, cylindrical multinucleated cells with diameters of 10-100 μm. During embryonic muscle development, mesenchymal myoblasts (L. myo, muscle) fuse, forming myotubes with many nuclei. Myotubes then further differentiate to form striated muscle fibers. Elongated nuclei are found…[Read more]

The Cerebellum The cerebellum, important for coordination, appears as a highly ordered tissue with distinct layers including the cell dense granular layer and the fiber rich but sparsely cell populated molecular layer, between which the large Purkinje cells (specialized neuronal cells) are located.

Cerebellum is one of the primary structures in the hindbrain. It is located under the occipital and temporal lobes of the cerebral cortex. It is an integrak structure for the transmission of sensory signals to mthe motor portions of the brain. It coordinates voluntary movements and maintains posture, balance, coordination, and speech.

Smooth muscle, also called involuntary muscle, muscle that shows no cross stripes under microscopic magnification. It consists of narrow spindle-shaped cells with a single, centrally located nucleus. Smooth muscle tissue, unlike striated muscle, contracts slowly and automatically. It constitutes much of the musculature of internal organs and the…[Read more]
