afferent fiber การใช้

• They contain both preganglionic parasympathetic fibers as well as visceral afferent fibers.
• The cell bodies of somatic sensory afferent fibers lie in ganglia throughout the spine.
• Visceral afferent fibers go to spinal cord following pathway of pelvic splanchnic nerve fibers.
• It is composed entirely of afferent fibers.
• Signals from these cells are also transmitted along afferent fibers and on to the brain.
• They also contain visceral afferent fibers.
• Because these afferent fibers are also part of a reflex arc, lordosis can be triggered reflexively.
• Afferent fibers from the body and columns of the fornix polysynaptically excite both superficial and deep neurons.
• They are less sensitive than the encapsulated afferent fibers and generally function in the perception of pain.
• These cells are in contact with afferent fibers that are responsible for transmitting signals to the brain.
• These afferent fibers project onto the spinal cord and synapse with the spinal interneurons called Ib inhibitory interneurons.
• The inferior cerebellar peduncle receives input from afferent fibers from the vestibular nuclei, spinal cord and the tegmentum.
• Nerve fibers for taste are supplied by the chorda tympani branch of cranial nerve VII via special visceral afferent fibers.
• Neurons of the cingulum receive afferent fibers from the parts of the thalamus that are associated with the spinothalamic tract.
• Sensation from the bladder is transmitted to the central nervous system ( CNS ) via general visceral afferent fibers ( GVA ).
• Specialized receptor cells called mechanoreceptors often encapsulate afferent fibers to help tune the afferent fibers to the different types of somatic stimulation.
• Specialized receptor cells called mechanoreceptors often encapsulate afferent fibers to help tune the afferent fibers to the different types of somatic stimulation.
• Impressions are made on the peripheral afferent fiber-endings; these create sensations which are transmitted to the center of the nervous system.
• Briefly, ion channels of the transient receptor potential ( TRP ) family, are found in the nerve endings of primary afferent fibers.
• Mechanoreceptors also help lower thresholds for action potential generation in afferent fibers and thus make them more likely to fire in the presence of sensory stimulation.
