Muscle fibers within the fascicle are surrounded by endomysium (320x). connective tissue, therefore, enclose and separate all parts of a skeletal muscle. This arrangement allows the parts to move somewhat independently. Also, many blood vessels and nerves pass through these layers.hese sections contain bundles of skeletal muscle fibers called fascicles (fasciculi). Each muscle fiber within a fascicle (fasciculus) lies within a layer of connective tissue in the form of a thin covering called endomysium (figs. 9.2 and 9.3).
a. skeletal muscle: multinucleated, striated; attached to bones producing locomotion, general support and posture; producing heat. Contraction is voluntary, and not long-sustained. b. Cardiac muscle: found only in the heart and responsible for contraction of cardiac tissue and distribution of blood.
