Question

Quizplus · Accepted Answer

The perimysium is the connective tissue sheath that surrounds and binds together bundles of muscle fibers. The epimysium and endomysium are also types of connective tissue surrounding muscles, but they surround the entire muscle and individual muscle fibers, respectively, rather than bundles of muscle fibers. The periosteum, on the other hand, is a connective tissue membrane that covers bones, not muscles.
