Question

what is the perimysium?
a connective tissue sheath bundling many muscle fibers into a fascicle
a connective tissue sheath surrounding an entire muscle
the plasma membrane of an individual muscle cell
a layer of loose connective tissue layer surrounding each individual muscle cell

Explanation:

The perimysium is a connective - tissue sheath that bundles multiple muscle fibers together to form a fascicle. The other options describe other muscle - related structures: the connective tissue sheath surrounding an entire muscle is the epimysium, the plasma membrane of an individual muscle cell is the sarcolemma, and the layer of loose connective tissue surrounding each individual muscle cell is the endomysium.

Answer:

A. A connective tissue sheath bundling many muscle fibers into a fascicle
