Question

Many axons are bundled together into fascicles and surrounded by which connective tissue layer?

Answer 1

Axons bundled into fascicles within a nerve are surrounded by the perineurium, a connective tissue layer that provides protection and support.

Step-by-step explanation:

Many axons bundled into fascicles within a nerve are surrounded by a layer of connective tissue known as the perineurium. This protective layer is similar to the perimysium in muscle tissue, which covers muscle fascicles. The nerve itself has multiple layers of protective coverings, including the epineurium on the outside and the endoneurium surrounding individual axons, ensuring their protection and the efficient transmission of nerve signals.
