  2. Sensory neuron - Wikipedia

    en.wikipedia.org/wiki/Sensory_neuron

    Four types of sensory neuron. Sensory neurons, also known as afferent neurons, are neurons in the nervous system, that convert a specific type of stimulus, via their receptors, into action potentials or graded receptor potentials. [1] This process is called sensory transduction. The cell bodies of the sensory neurons are located in the dorsal ...

  3. Group A nerve fiber - Wikipedia

    en.wikipedia.org/wiki/Group_A_nerve_fiber

    This pathway describes the first-order neuron. Aδ fibers serve to receive and transmit information primarily relating to acute pain (sharp, immediate, and relatively short-lasting). This type of pain can result from several classifications of stimulants: temperature-induced, mechanical, and chemical.

    A neuron (also known as a neurone or nerve cell) is an excitable cell in the nervous system that processes and transmits information by electrochemical signaling. Neurons are the core components of the brain, spinal cord, and peripheral nerves. Soma; Axon; Myelin; Dendrite; Dendritic spine

  5. General somatic afferent fiber - Wikipedia

    en.wikipedia.org/wiki/General_somatic_afferent_fiber

    The general somatic afferent fibers (GSA or somatic sensory fibers) are afferent fibers that arise from neurons in sensory ganglia and are found in all the spinal nerves, except occasionally the first cervical.

    English: Complete neuron cell diagram. Neurons (also known as neurones and nerve cells) are electrically excitable cells in the nervous system that process and transmit information. In vertebrate animals, neurons are the core components of the brain, spinal cord and peripheral nerves.

  7. Free nerve ending - Wikipedia

    en.wikipedia.org/wiki/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 that often result ...

  8. Nociceptor - Wikipedia

    en.wikipedia.org/wiki/Nociceptor

    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.
