Nerve Endings:

Nerve endings communicate with the brain about internal/external and voluntary/involuntary experiences in the environment. Nerve endings refer to the very tip of a nerve fiber, which is the end of a neuron’s (nerve cell’s) axon. Both the nerve ending and the neuron’s terminal axon describe the point where a nerve transmits signals to another cell, with this difference: nerves are bundles of neurons wrapped together, forming a larger fiber that transmits signals along a pathway. They are complex structures where multiple neurons converge at a single point to interact with a target tissue. Also see Neurons and Neuron Endings
