Question

Name the connective tissue layers that surround each muscle fiber, fascicle, muscle, and group of muscles. (muscle cell\fiber, epimysium, perimysium, endomysium)

Answer 1

In skeletal muscles, each muscle fiber is surrounded by the endomysium, fascicles by the perimysium, and the entire muscle is encased in the epimysium; these layers also contribute to tendon formation.

Step-by-step explanation:

The skeletal muscle structure involves three connective tissue layers that play pivotal roles in providing support and compartmentalization for muscle fibers and groups of muscles. Each individual muscle fiber, also known as a muscle cell, is enclosed by a thin layer called the endomysium. Muscle fibers are grouped into bundles termed fascicles, which in turn are wrapped in a layer known as the perimysium.

Collectively, a number of fascicles are wrapped by a thicker layer called the epimysium, which covers the entire muscle. When muscles form groups, these layers extend and contribute to the formation of tendons that anchor muscles to bones, providing a robust framework for muscle movement and force distribution.
