Solution
The correct option is B Perimysium Perimysium is a sheath of connective tissue that groups muscle fibers into bundles or fascicles. The perimysium plays a role in transmitting lateral contractile movements.
Epimysium is a layer of connective tissue, which ensheaths the entire muscle and protects muscles from friction against other muscles and bones. It is composed of dense irregular connective tissue.
The endomysium is a wispy layer of areolar connective tissue that ensheaths each individual myocyte (muscle fiber, or muscle cell).
