MEDICAL PHYSIOLOGY

Detailed explanation-1: -Deep to the endomysium, each skeletal muscle cell is surrounded by a cell membrane known as the sarcolemma (You will see the prefixes sarc-and myo-quite a bit in this discussion, so you should understand that these are prefixes that refer to “muscle").

Detailed explanation-2: -Superficial fascia is found directly under the skin and superficial adipose layers. It can show stratification both grossly and microscopically. Traditionally, it is described as being made up of membranous layers with loosely packed interwoven collagen and elastic fibers.

Detailed explanation-3: -The papillary dermis is the superficial layer, lying deep to the epidermis. The papillary dermis is composed of loose connective tissue that is highly vascular.

Detailed explanation-4: -The correct answer is (b): Endomysium covers the individual muscle fibers, and the epimysium covers the whole muscle. Endomysium is the innermost layer and coves individual muscle fibers.
