Question

Skeletal muscles are invested with distinct layers of connective tissue. What are the layers of connective tissue that surround skeletal muscles?

1) Endomysium, perimysium, and epimysium
2) Muscle fibers
3) Large blood vessels and nerves
4) None of the above

Answer 1

Skeletal muscles are invested with distinct layers of connective tissue that surround and support the muscle fibers. These layers include endomysium, perimysium, and epimysium.

Step-by-step explanation:

Skeletal muscles are invested with distinct layers of connective tissue that surround and support the muscle fibers. These layers include:

1. Endomysium: This is the innermost layer of connective tissue that surrounds each individual muscle fiber. It provides support and nutrients to the muscle fiber.
2. Perimysium: This is the middle layer of connective tissue that surrounds and bundles together groups of muscle fibers called fascicles. It also contains blood vessels and nerves that supply the muscle fibers.
3. Epimysium: This is the outermost layer of connective tissue that surrounds the entire skeletal muscle. It provides protection and stability to the muscle as a whole.
