Neurology. Small fiber peripheral neuropathy is a type of peripheral neuropathy that occurs from damage to the small unmyelinated and myelinated peripheral nerve fibers. These fibers, categorized as C fibers and small Aδ fibers, are present in skin, peripheral nerves, and organs. [1] The role of these nerves is to innervate some skin ...
nerve fiber. Anatomical terms of neuroanatomy. [edit on Wikidata] Group C nerve fibers are one of three classes of nerve fiber in the central nervous system (CNS) and peripheral nervous system (PNS). The C group fibers are unmyelinated and have a small diameter and low conduction velocity, whereas Groups A and B are myelinated.
Free nerve ending. 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 ...
The other two classes are the group B nerve fibers, and the group C nerve fibers. Group A are heavily myelinated, group B are moderately myelinated, and group C are unmyelinated. [1] [2] The other classification is a sensory grouping that uses the terms type Ia and type Ib, type II, type III, and type IV, sensory fibers. [1]
C tactile afferents are nerve receptors in mammalian skin that generally respond to nonpainful stimulation such as light touch. For this reason they are classified as ‘low-threshold mechanoreceptors’. As group C nerve fibers, they are unmyelinated and have slow conduction velocities. They are mostly associated with the sensation of pleasant ...
A nociceptor (from Latin nocere 'to harm or hurt'; lit. 'pain receptor') is a sensory neuron that responds to damaging or potentially damaging stimuli by sending "possible threat" signals [1][2][3] to the spinal cord and the brain. The brain creates the sensation of pain to direct attention to the body part, so the threat can be mitigated; this ...
Cutaneous innervation refers to an area of the skin which is supplied by a specific cutaneous nerve. Dermatomes are similar; however, a dermatome only specifies the area served by a spinal nerve. In some cases, the dermatome is less specific (when a spinal nerve is the source for more than one cutaneous nerve), and in other cases it is more ...
4.1%-12.4% (12-month prevalence, US adults) [1] Neuropathic pain is pain caused by a lesion or disease of the somatosensory nervous system. [2][3] Neuropathic pain may be associated with abnormal sensations called dysesthesia or pain from normally non-painful stimuli (allodynia). It may have continuous and/or episodic (paroxysmal) components.
