Free nerve ending

Index Free nerve ending

A free nerve ending (FNE) or bare nerve ending, is an unspecialized, afferent nerve fiber ending of a sensory neuron. [1]

16 relations: Afferent nerve fiber, Axon, Cutaneous receptor, Free nerve ending, Group A nerve fiber, Group C nerve fiber, Mechanoreceptor, Nerve, Nociception, Nociceptor, Sensory neuron, Skin, Stimulus modality, Stratum granulosum, Thermoreceptor, Vertebrate.

Afferent nerve fiber

Afferent nerve fibers refer to axonal projections that arrive at a particular region; as opposed to efferent projections that exit the region.

Axon

An axon (from Greek ἄξων áxōn, axis) or nerve fiber, is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses known as action potentials, away from the nerve cell body.

Cutaneous receptor

The cutaneous receptors are the types of sensory receptor found in the dermis or epidermis.

Group A nerve fiber

Group A nerve fibers are one of the three classes of nerve fiber as generally classified by Erlanger and Gasser.

Group C nerve fiber

Group C nerve fibers are one of three classes of nerve fiber in the central nervous system and peripheral nervous system.

Mechanoreceptor

A mechanoreceptor is a sensory receptor that responds to mechanical pressure or distortion.

Nerve

A nerve is an enclosed, cable-like bundle of axons (nerve fibers, the long and slender projections of neurons) in the peripheral nervous system.

Nociception

Nociception (also nocioception or nociperception, from Latin nocere 'to harm or hurt') is the sensory nervous system's response to certain harmful or potentially harmful stimuli.

Nociceptor

A nociceptor is a sensory neuron that responds to damaging or potentially damaging stimuli by sending “possible threat” signals to the spinal cord and the brain.

Sensory neuron

Sensory neurons also known as afferent neurons are neurons that convert a specific type of stimulus, via their receptors, into action potentials or graded potentials.

Skin

Skin is the soft outer tissue covering vertebrates.

Stimulus modality

Stimulus modality, also called sensory modality, is one aspect of a stimulus or what we perceive after a stimulus.

Stratum granulosum

The stratum granulosum (or granular layer) is a thin layer of cells in the epidermis.

Thermoreceptor

A thermoreceptor is a non-specialised sense receptor, or more accurately the receptive portion of a sensory neuron, that codes absolute and relative changes in temperature, primarily within the innocuous range.

Vertebrate

Vertebrates comprise all species of animals within the subphylum Vertebrata (chordates with backbones).
