Sensory afferent pathway

WebThe altered GI sensation in diabetes may be due to altered mechanoreceptor function and afferent pathways rather than being a central phenomenon. As most studies on GI sensory function in diabetes were performed in human beings, it is difficult to locate the origin in the peripheral organ and nerves. Web1 Jan 2011 · These effectors are regulated by parallel but distinct, effector-specific neural pathways that share a common peripheral thermal sensory input. The thermal afferent circuits include cutaneous thermal receptors, spinal dorsal horn neurons and lateral parabrachial nucleus neurons projecting to the preoptic area to influence warm-sensitive ...

Afferent nerve fiber - Wikipedia

Afferent neurons are pseudounipolar neurons that have a single process leaving the cell body dividing into two branches: the long one towards the sensory organ, and the short one toward the central nervous system (e.g. spinal cord). These cells do have sensory afferent dendrites, similar to those typically inherent in neurons. They have a smooth and rounded cell body located in the ganglia of th… WebLung sensory receptors with afferent fibers coursing in the vagus nerves are broadly divided into three groups: slowly (SAR) and rapidly (RAR) adapting stretch receptors and … WebThey convert external sensory stimuli like touch, pain, sense of heat, smell, as well as visual and auditory inputs into an internal electrical impulse.
