PATHOLOGY

Detailed explanation-1: -To accomplish this, a nucleus in the medulla called the nucleus of the solitary tract receives information from stretch receptors in blood vessels. These receptors—called baroreceptors—can detect when the walls of blood vessels expand and contract, and thus can detect changes in blood pressure.

Detailed explanation-2: -Within this region, discrete groups of neurons act to generate and maintain the sympathetic vasomotor tone and arterial blood pressure. The medulla oblongata also contains the main site integrating signals arising from high-and low-pressure baroreceptors and chemorecep tors afferents.
