To determine:
The relationship of muscle structure that is associated with endomysium, perimysium, and epimysium.
Introduction:
A muscle is containing connective tissue, nerves, and blood vessels. A framework of connective tissue is providing a distinct shape to their muscles.
Explanation of Solution
A muscular structure contains connective tissue that is present from the smallest to largest and deep to superficial. A muscle structure consists of three different structures, such as endomysium, perimysium, and epimysium.
Endomysium:
Endomysium is a thin sleeve loose connective tissue that helps to cover the muscle fiber. It allows blood capillaries and nerve fibers to attach with the muscle fiber. The application of muscle fiber depends upon the exchange of calcium, potassium, and sodium ions between the endomysial tissue fluid, muscle fiber, and nerve tissue.
Perimysium:
Perimysium is a thicker connective tissue sheath that helps to fold the muscle fibers into bundles. This folding is known as fascicles. Perimysium is responsible for carrying large nerve and blood vessels.
Epimysium:
Epimysium is a fibrous sheath that is used to cover the whole muscle. The outer surface of epimysium is known as fascia, and the inner surface lies between the fascicles to develop perimysium.
The endomysium, perimysium, and epimysium are three different connective tissue that is associated with the muscle structure. These three different connective tissue cover the muscle fiber in various ways such as endomysium, provide a room to blood capillaries and nerve tissue that attach with the connective tissue; Perimysium warps the muscle fiber into bundles; and, epimysium covers the entire muscles.
