What does the epimysium blend into to form the tendon?

• A. A connective tissue to form the tendon
• B. A circular muscle layer
• C. A nerve sheath
• D. A muscle fiber bundle

Answer: (A)

The epimysium is the outermost layer of connective tissue around a whole muscle, and its collagen fibers extend beyond the muscle to merge with the tendon. This continuity creates a continuous sheet of dense connective tissue that forms the tendon, the structure that transmits the muscle’s pulling force to bone. The idea that the epimysium blends into a connective tissue to form the tendon fits because tendons are made of dense regular connective tissue organized to withstand tension. The other options don’t fit this idea: there isn’t a circular muscle layer forming the tendon, a nerve sheath isn’t involved in attaching muscle to bone, and a muscle fiber bundle is wrapped by perimysium, not formed from the epimysium itself.
