The connective tissue covering that encloses the sarcolemma of an individual muscle fiber is called the (a) epimysium, (b) perimysium, (c) endomysium, (d) periosteum.

To determine:
The name of the connective tissue that encloses the sarcolemma of individual muscle fiber as a covering is:
Epimysium
Perimysium
Endomysium
Periosteum
Answer to Problem 1MC
Solution:
(c) Endomysium: The sarcolemma of the muscle fiber of an individual is covered by the endomysium connective tissue.
Explanation for the correct answer:
The sarcolemma is a sheath, in the form of a tube that envelops the skeletal muscles. The muscle fiber is covered by three layers, namely, perimysium, epimysium, and, endomysium. Furthermore, it is endomysium (“endo” referring to inside) layer that is the innermost layer and forms the immediate covering of the muscle fiber. This layer helps in excitation and contraction of muscle fibers. Thus option (c) is considered as correct option.
Explanation of Solution
Explanation for the incorrect answers:
Option (a) is given as epimysium. Epimysium is the connective tissue that encloses the whole muscle, whereas endomysium wraps the sarcolemma of the individual muscle fiber. Thus option (a) is considered as an incorrect answer.
Option (b) is given as perimysium. Perimysium is the connective tissue that wraps the bundles of muscle fibers (fascicles), whereas endomysium wraps the sarcolemma of the individual muscle fiber. Thus option (b) is considered as an incorrect answer.
Option (d) is given as periosteum. The periosteum is a membrane that covers the bones outer surface, except at the surfaces of joints. Thus not involve in wrapping of muscle fiber of an individual. So option (d) is considered as an incorrect answer.
Hence, option (a), (b) and (d) are the incorrect options.
Thus it is concluded that endomysium is a connective tissue that encloses the sarcolemma of the muscle fiber of an individual.
