Question

Each muscle fibre is directly surrounded by connective tissues called the ______

a. perimysium
b. fascia
c. endomysium
d. epimysium

Answer 1

Each muscle fiber is encased in a thin connective tissue layer known as the endomysium, which directly surrounds the fiber and provides support and nutrients. Option c is correct.

Step-by-step explanation:

Each muscle fiber is directly surrounded by connective tissues called the endomysium. Inside each skeletal muscle, muscle fibers are organized into individual bundles, each called a fascicle, which are covered by a layer of connective tissue called the perimysium.

The skeletal muscle fibers are then wrapped in another connective tissue called the epimysium. The function of these tissues is to support and protect muscle fibers, allow them to withstand the forces of contraction, provide pathways for nerves and blood vessels, and anchor the muscles to tendons.
