Muscle cells are grouped into muscle fascicles by enveloping perimysium connective tissue. Fascicles are bundled together by epimysium connective tissue. Muscle fascicles typically only contain one type of muscle cell (either type I fibres or type II fibres), but can contain a mixture of both types.

WebbThe size, number, and pattern of fascicles vary in different nerves and at different levels along their paths. Generally, their number increases and their size decreases at some distance proximal to the branching point. NEURONS. A neuron is the structural and functional unit of the nervous system. It includes the cell body, dendrites, and axon. WebbThe most striking feature of skeletal muscle fibers is the presence of striations, or lines, visible in longitudinal sections of the muscle. The striations are the result of the precise arrangement of actin and myosin into repeating units called sarcomeres that create a characteristic pattern of transverse bands.
