afferent nerve การใช้

• Afferent nerve endings without mechanoreceptor cells are called free nerve endings.
• Sensory afferent nerves trigger a systemic sympathetic activation leading to marked vasoconstriction.
• It then travels along the afferent nerves toward the central nervous system.
• Paresthesia coverage depends upon which afferent nerves are stimulated.
• A single afferent nerve fibre branches to innervate up to 90 such endings.
• Ganglia house the cell bodies of afferent nerves.
• See Wikipedia articles Nerve and Afferent nerve fiber.
• Afferent nerve fibers responsible for sensory stimulus detection and feedback are especially sensitive to stimulation.
• This results from the specialized mechanoreceptor cells that are superimposed upon the afferent nerve fibers.
• The parasympathetic reflex loop consists of afferent nerve endings which originate under the inner lining of the bronchus.
• A single taste bud is innervated by several afferent nerves, while a single efferent fiber innervates several taste buds.
• All of the axons in the dorsal root, which contains afferent nerve fibers, are used in the transduction of somatosensory information.
• The region of the basilar membrane supplying the inputs to a particular afferent nerve fibre can be considered to be its receptive field.
• Motor nerves are often paired with sensory nerves, which are bundles of afferent nerve fibers that travel from the PNS to the CNS.
• They are abundant in highly sensitive skin like that of the fingertips in humans, and make synaptic contacts with somatosensory afferent nerve fibers.
• Afferent nerve fibers are excited or inhibited depending on whether the hair cells they arise from are deflected in the preferred or opposite direction.
• The medial reticular formation and lateral reticular formation are two columns of neuronal nuclei with ill-defined boundaries that send projections through the afferent nerves.
• To produce this reflex, branches of the afferent nerve fibers cross from the stimulated side of the body to the contralateral side of the spinal cord.
• Afferent nerves in the parasympathetic and sympathetic systems of the autonomic nervous system differently innervate various organs that maintain homeostasis such as the heart and the face.
• Muscle spindle discharges are sent to the spinal cord through afferent nerve fibers, where they activate monosynaptic and polysynaptic reflex arcs, causing the muscle to contract.
