5) Nerves and blood vesselsthat service a muscle fiber arelocated in the connectivetissues of itsA) myofibrils. B) sarcolemma. C) sarcomere. D) endomysium. E) perimysium.

D. endomysium

Explanation:

The muscle tissues are surrounded by connective tissues which in turn protect them. A sheet or band of irregular connective tissue that supports and surrounds muscles is called fascia. From fascia, three distinct layers of connective tissues originate that protect the skeletal muscles. These three layers are epimysium, perimysium, and endomysium.

Endomysium extends into the interior of each fascicle. It serves to separates individual muscle fibers from one another. The endomysium is mostly reticular fibers but also has blood vessels, lymphatic vessels, and the associated nerves.
