Question

identify the highlighted structures.

Explanation:

The image appears to be a histological section of muscle tissue. The highlighted structure's yellow - orange color and appearance suggest it could be collagen fibers in the endomysium or perimysium, which are connective tissue components in muscle. Collagen provides strength and support to the muscle tissue.

Connective tissue (likely collagen fibers in endomysium/perimysium)
