The medulla oblongata helps regulate breathing, heart and blood vessel function, digestion, sneezing, and swallowing. This part of the brain is a center for respiration and circulation. Sensory and motor neurons (nerve cells) from the forebrain and midbrain travel through the medulla.

Additionally, what structures are found in the medulla? The Medulla Oblongata Characteristic structures of the medulla include the pyramid (containing corticospinal fibers), olivary eminence, pre- and post-olivary sulci, restiform body, and tubercles formed by the gracile and cuneate nuclei and fibers of the spinal trigeminal tract.

Besides, what does the medulla oblongata consist of?

The medulla consists of both myelinated (white matter) and unmyelinated (gray matter) nerve fibres, and, similar to other structures in the brainstem, the white matter of the medulla, rather than lying beneath the gray matter, is intermingled with the latter, giving rise to part of the reticular formation (a network of

What happens when medulla is damaged?

The medulla oblongata connects our brain and our spinal cord with most of our sensory and motor fibres either crossing into the brain or finishing at this level (Farrell & Dempsey 2013). Damage to the medulla oblongata can result in: Difficulty swallowing. Loss of gag and cough reflex.
