What are the different parts of Medulla Oblongata?

Medulla Oblongata along with the lower olive, pyramids and pony form an area of ​​the brain known as the brain stem. This area is responsible for the processes of the autonomic nervous system that controls heart rate, breathing, sensitivity to pain, vomiting and vasomotor reflexes. Because the part of the brain stem that connects PONS with the mix, Medulla Oblongata would easily be confused to the backbone tissue if it was not for a clear pyramidal structure on its sides. Medulla Obrongata is mainly formed by white and gray matter; It also contains communication tracts that carry messages between hemispheres and between brain and spinal cord. Since the whole structure measures less than 1.2 inches (3 cm) in length, the individual functions of most of its microscopic elements are not well known. These are found both deep within medulla and on its surface. The deepest fibers are the most common and connect the cores of Funiculus gracilis, Funiculus cuneatus and a remmonial body to Raphe.

Raphe is located just above the pyramids in the middle of the MeDully Oblongata. It consists of a thick mixture of neurons and nerve fibers. Its fibers spread in many ways, some of which connect to the fourth chamber floor.

Sometimes considered the most unclean part of the pinks, the fourth chamber can also be considered the highest part of Medully Obrongata. The hypoglossal nucleus and core of the ambiguous are found in it, as well as the point of origin of both hypoglossal and glossopharyngeal additional nerves. This diamond -shaped structure has a floor and roof. The roof consists of a medullary velo and the floor consists of a fossil fossils formatio reticularis.

formatio reticularis is an unusual structure located behind the olive and pyramids. It consists of bundles of nerve fibers arranged to an angle of 90 degrees together. They join olive, spinal cord, funiculus cuneatus and funiculus gracilis.

Gray matter is located throughout the side of Medully. In it lies a large amountHe knows vital cores that are used to transmit sensory information from the peripheral nervous system. Gray matter also contains many cranial nerves.
