PATHOLOGY

Detailed explanation-1: -Your medulla oblongata is the bottom-most part of your brain. Its location means it’s where your brain and spinal cord connect, making it a key conduit for nerve signals to and from your body. It also helps control vital processes like your heartbeat, breathing and 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.

Detailed explanation-3: -Increased activity of the rostral ventrolateral medulla (RVLM) neurons is transmitted to the intermediolateral (IML) cell column of the spinal cord, where peripheral sympathetic nerves to the heart, arterioles and kidneys are activated, thus increasing blood pressure (BP).
