Question

a. sarcolemma c. fascia
b. endomysium d. epimysium

Answer 1

C
Skeletal muscle fibers are multinucleated and surrounded by an electrically polarized membrane called the sarcolemma. The endomysium, the first of three connective tissues in muscles, surrounds the sarcolemma. The entire skeletal muscle consists of bundles of muscle fibers that form a fascicle. The fascicle is surrounded by the second layer of connective tissue called the perimysium. The epimysium, a coarse irregular connective tissue connects to the perimysium and surrounds the muscle. The entire muscle is surrounded by a layer of areolar tissue called fascia that covers the epimysium. Muscles are surrounded and divided by fibrous envelopes called fascia.
