WebReflexes may be classified into somatic and visceral (autonomic) based on motor response. Somatic reflexes involve the contraction of voluntary (skeletal) muscles whereas visceral reflexes involve the secretion of glands or the contraction of smooth muscles. In this lab, we will explore both somatic and visceral reflexes. WebFacilitation refers to the partial excitation of neurons caused by various reflexes, including somato-somatic, somatovisceral, viscerocutaneous, viscerosomatic, and viscero …
WebSchematic diagram of the reflex pathways for the somato-somatic and somato-autonomic reflexes (from Sato A. et al. 1997 []).Somatic stimulation of limb tissues elicits reflexes mediated primarily at the supraspinal level (in the brain), whereas somatic stimulation within the distribution of the thoracolumbar spinal nerves (the trunk region) has the potential to … WebIt is essential for the osteopathic physician to understand and have committed to memory the somatic regions that are likely to be effected by viscero-somatic reflexes resulting from visceral pathology ( Click here to open the sympathetic drill exercise).
