WebYour 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. Appointments 866.588.2264 Appointments & Locations WebJan 1, 2010 · Caudal to the pons is the medulla, containing the nuclei for cranial nerves IX, X, XI, XII and a portion of V. Ascending spinocerebellar tracts form the inferior cerebellar peduncle at this level. The ascending sensory tracts from the body (posterior columns) terminate in the posterior column nuclei (gracilis, cuneatus) in the lower medulla. WebJul 25, 2024 · The tectum of the medulla involves the inferior medullary velum, which is the most inferior posterior part of the fourth ventricle. The tegmentum consists of the inferior olivary nucleus and the cranial nerve nuclei of IX, X, XI, XII. The basis, most ventral layer, has the pyramid decussation at the medulla. ow22sq
