Sensory nerve - wikipedia Sensory nerve Sensory nerve Details Identifiers Latin nervus sensorius TA A14. 2.00. 022 FMA 5868 Anatomical terms of neuroanatomy ( edit on Wikidata ) A sensory nerve, also called an afferent nerve, is a nerve that carries sensory information toward the central nervous system ( CNS ). It is a cable - like bundle of the afferent nerve fibers coming from sensory receptors in the peripheral nervous system ( PNS ). A motor nerve carries information from the CNS to the PNS, and both types of nerve are called peripheral nerves. Afferent nerve fibers link the sensory neurons throughout the body, in pathways to the relevant processing circuits in the central nervous system. Afferent nerve fibers are often paired with efferent nerve fibers from the motor neurons ( that travel from the CNS to the PNS ), in mixed nerves. Stimuli cause nerve impulses in the receptors and alter the potentials, which is known as sensory transduction. Contents 1 Spinal cord entry 2 Nerve damage 3 References 4 External links Spinal cord entry Afferent nerve fibers leave the sensory neuron from the dorsal root ganglia of the spinal cord, and motor commands carried by the efferent fibers leave the cord at the ventral roots. The dorsal and some of the ventral fibers join as spinal nerves or mixed nerves. Nerve damage This section needs additional citations for verification.

( January 2017 ) Damage to the sensory nerve causes a wide range of symptoms because of the amount of functions performed by the nerve. Traumatic injuries and other damages to the sensory nerves can lead to peripheral neuropathy, which in turn can lead to things such as chronic liver disease, kidney disease, cancer, vitamin B deficiency, etc. The ability to feel pain or changes in temperature can be affected by damage to the fibers in the sensory nerve. This can cause a failure to notice injuries such as a cut or that a wound is becoming infected. There may also be a lack of detection of heart attacks or other serious conditions. The lack of detection of pain and other sensations is a particularly large problem for those with diabetes, which contributes to the rate of lower limb amputations among this population. Overall, the poor sensation and detection may lead to changes in skin, hair, joint, and bone damage over the years for many people.

Question: where are sensory and motor fibers located in the skin
Answer: A sensory nerve, also called an afferent nerve, is a nerve that carries sensory information toward the central nervous system (CNS). It is a cable-like bundle of the afferent nerve fibers coming from sensory receptors in the peripheral nervous system
