Nerve fibers are specialized structures that transmit electrical signals in the nervous system, facilitating communication between the brain, spinal cord, and peripheral tissues. They play a crucial role in conveying sensory information, such as touch and pain, as well as motor commands to muscles. Nerve fibers can be classified into different types based on their diameter and conduction speed, influencing their specific functions in reflex actions and voluntary movements. Overall, their primary function is to ensure rapid and efficient signal transmission, enabling coordinated bodily responses.
No, a nerve fiber cannot survive without its cell body or axon. The cell body provides nutrients and support to the axon, while the axon is responsible for transmitting signals. Without either of these components, the nerve fiber would no longer function.
Arevbranching fibers at the end of the axon that lead the nervous impulse from the axon to the synapse
Regeneration of a nerve fiber in the peripheral nervous system (PNS) is possible if the cell body of the nerve remains intact and the nerve fibers are only partially damaged. In this case, the Schwann cells in the PNS can guide the regrowth of the nerve fibers. However, regeneration is a slow process and may not always result in full recovery of function.

The reason why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves is owing to nerve plexuses. These are networks of nerves all tangled together and found mostly in the limbs.

Basically, a nerve is a fiber that connects the brain and spinal cord with various parts of the body (aka - receptor organs).
