WebSensory neurons can have either (a) free nerve endings or (b) encapsulated endings. Photoreceptors in the eyes, such as rod cells, are examples of (c) specialized receptor cells. These cells release neurotransmitters onto a bipolar …
Nerves: Types, Function & Anatomy - Cleveland Clinic
WebWhen a nerve sends an electrical impulse: The signal travels down the axon, the “wiring” connection of the nerve. The message converts to a chemical signal at the end of the nerve called the axon hillock. The chemical releases molecules called neurotransmitters, into a space that bridges the space between one neuron to another.
Free nerve ending - Wikipedia
WebA free nerve ending (FNE) or bare nerve ending, is an unspecialized, afferent nerve fiber sending its signal to a sensory neuron. Afferent in this case means bringing information from the body's periphery toward the brain. They function as cutaneous nociceptors and are essentially used by vertebrates to detect noxious stimuli that often result ...
