Question

T/F

Layers of connective tissue that extend into muscle and form compartments within the muscle are fascicles.

Answer 1

Fascicles are muscle fiber bundles surrounded by perimysium, not layers of connective tissue themselves, so the statement is false. The three types of connective tissue in muscle are endomysium, perimysium, and epimysium.

Step-by-step explanation:

The statement is false. Fascicles are indeed bundles of muscle fibers within skeletal muscle but they are not layers of connective tissue themselves. Instead, fascicles are surrounded by a type of connective tissue known as perimysium. This connective tissue compartmentalizes the muscle fibers into fascicles and works in conjunction with epimysium that envelops the entire muscle and endomysium that encases each individual muscle fiber. These three layers of connective tissue provide structure to the muscle, facilitate its contraction, and carry blood vessels and nerves throughout the muscle.
