The Medulla Oblongata is a cone-shaped, neuronal cluster in the hindbrain. It is the lowest part of the brainstem located in front of the cerebellum and is connected to the midbrain by the pons moving down to the spinal cord. The main compositions of Medulla Oblongata are cranial nerve nuclei IX-to-XII, white matter tracts, and gray matter.
It helps in transmitting messages between the spinal cord and various sections of the brain. It is responsible for controlling various autonomic functions in the body, such as digestion, blood vessel functions, heart vessel functions, breathing, sneezing, and swallowing.
Features of Medulla Oblongata
Some features of medulla oblongata are as follows:
Median Fissures – These are the shallow groves situated along the posterior and anterior regions of the medulla.
Pyramid – These are two circular masses situated on the opposite areas of the anterior median fissure. The medulla is connected to the spinal cord, cerebral cortex, and pons with the nerve fibers.
Olive – These are coupled oval structures on the surface of medulla comprising never fibers connecting the medulla to the cerebellum and pons.
Fasciculus Gracilis – The bundle of the nerve fiber tract extends to the medulla from the spinal cord.
Medulla Oblongata Location
The Medulla Oblongata is located at the lowest part of the brain stem. It is one of the imperative parts of the brain that helps to regulate numerous important functions of the body. Any damage caused to Medulla is very difficult and sometimes impossible to fix.
