Final Answer:
The endomysium is a connective tissue that surrounds the muscle fiber. The perimysium is a connective tissue that surrounds the muscle fascicle. Hence, the correct option is 1).
Step-by-step explanation:
The organization of skeletal muscles involves a hierarchical structure, with connective tissues playing crucial roles. The endomysium is the connective tissue that surrounds individual muscle fibers. Each muscle fiber is a single muscle cell, and the endomysium provides support and protection to these individual fibers. Therefore, the correct pairing is "muscle fiber" for the endomysium.
On the other hand, the perimysium is the connective tissue that surrounds bundles of muscle fibers known as muscle fascicles. Muscle fascicles are groups of muscle fibers bundled together by the perimysium, which provides structural organization and support to these fascicles. Consequently, the accurate match for the perimysium is "muscle fascicle."
Understanding these connective tissues and their respective roles is fundamental in comprehending the structural integrity and functionality of skeletal muscles. The endomysium and perimysium, along with the epimysium (connective tissue surrounding the entire muscle), work in concert to maintain the structural integrity of muscles and facilitate their coordinated contractions. Hence, the correct option is 1).
