Impaired afferent pathways
WitrynaThe primary afferent neurons in this pathway are pseudounipolar neurons in the posterior root ganglia, whose central processes enter the posterior horn and synapse on second-order neurons located primarily in laminae III and IV (nucleus proprius) as well as area X, bordering the central canal.

Together with the medial lemnicus, it is one of the most important sensory pathways of the nervous system. It is responsible for the transmission of pain, temperature, and crude touch to the somatosensory region of the thalamus.
Witryna20 mar 1994 · This is the first report on a case of Shy-Drager syndrome complicated with SIADH and bilateral vocal cord paralysis. In this case, SIADH is caused by impaired afferent pathways from baroreceptors to the hypothalamus, which transfer inhibitory stimuli on ADH secretion.

WitrynaConsidering the complex innervation of most viscera by spinal and vagal afferent pathways, these neuroanatomic findings provide an explanation for why regional blocks or nerve dissections often result in only partial or temporary effects. ... Impaired function of viscera, such as decreased transit of material in the gut, may significantly ... Witrynadiagonal: efferent pathway lesion, i.e., middle-ear abnormality or seventh-nerve paralysis (when the lesion is proximal to the innervation of the stapedius) 4. vertical: afferent pathway lesion, i.e., eighth-nerve lesion with sufficient hearing impairment that the stapedius reflex cannot be elicited, i.e., vestibular neuroma. 5.

WitrynaThe term ‘arterial baroreceptor reflex ’ is used to refer to a variety of physiological responses elicited by changes in baroreceptor afferent activity. While the baroreceptor reflex is often used in specific reference to the reflexive change in ABP and heart rate brought about by changing autonomic outflow to the heart and vasculature, there are … shutdown guestWitryna4 kwi 2024 · Generally, one could speculate that fewer tonic neurons on afferent pathways might be a measure of a decreased afferent nerve activity in vivo. On the other hand, tonic and thus likely fast responding units might also subserve the sensitivity of afferent neural pathways. the oxford hotel denver phone numberWitrynaAfferent pathway function may be impaired by some factors, which should be considered by both clinicians and parents.
