Answer:
b. muscle fascicle
c. muscle fiber
d. myofibril and. sarcomere
Explanation:
When muscle contracts, the myosin and actin filaments slide antiparallel to one another hence shortening the distance between the adjacent Z-lines of a sarcomere (a functional unit of striated muscle). Technically, nonetheless, the filaments do not shorten. A chain of sarcomeres make up a myofibril. Myofibrils bound together in bundles around a sarcolemma make up a muscle fiber. Several muscle fibers bundled together in an endomysium make up a fascicle. Several fascicles bound together in a perimysium make up a muscle. A muscle has blood vessels and innervated nerves that serve the cells and are bound overall by an epimysium.
The blood vessels and nerves in the muscle do not contract.
