Free nerve endings receptors
WebThe sensory receptors of the crude touch, pain and temperature senses are bare or free nerve endings. That is, they are unencapsulated, do not end on or near specialized tissue, and may be mechanoreceptors, nociceptors or thermoreceptors. WebReceptors possess structural differences at the dendrite ends of sensory neurons. Those with unencapsulated free nerve endings include pain, cold, and heat receptors; those …

A 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 in pain.
