Muscle fibers are multinucleated muscle cells surrounded by which connective tissue?

Explanation:
The surrounding tissue for each skeletal muscle fiber is the endomysium. This is a delicate layer of loose connective tissue that sits between the sarcolemma (the muscle fiber’s membrane) and the underlying basal lamina. The endomysium contains capillaries and nerves that supply each individual fiber and also houses satellite cells important for repair. Surrounding a group of fibers is the perimysium, which forms a fascicle, and the entire muscle is wrapped by the epimysium. So the endomysium is the connective tissue directly encasing each multinucleated muscle fiber.
