Short section of the brain stem between the diancephalon and the pons. Functions include regulation of the heart respiratory and central nervous systems including consciousness and the sleep cycle. Namely they are the medial longitudinal fasciculus MLF and the medial trigeminal spinal and lateral lemnisci.

This video Brain Stem. Area posterior to the. The brainstem or brain stem is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord.

Neurons in and around the solitary tact and nucelus ambiguus respond by increasing respiration. The medulla oblongata helps regulate breathing heart and blood vessel function digestion sneezing and swallowing. Superior and inferior colliculi.

Conduit of ascending and descending tracts. It contains numerous cranial nerve nuclei and is traversed by multiple tracts between the brain and spinal cord. The pons is a major structure in the upper part of your brainstem.
