Final answer:
A muscle fiber is the same as a myocyte, which is a cell composed of myofibrils and enclosed by the sarcolemma.
Step-by-step explanation:
A muscle fiber can be correctly identified as a myocyte. Muscle fibers, or myocytes, are the cells that make up skeletal muscle tissue. Each muscle fiber is enclosed by a plasma membrane known as the sarcolemma, with a cytoplasm called the sarcoplasm. Muscle fibers contain myofibrils, which are composed of sarcomeres, the basic contractile units of muscle tissue. A fascicle, on the other hand, is a bundle of muscle fibers, and is a larger unit than an individual muscle fiber.
