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.
