The medulla oblongata or simply medulla is a long stem-like structure which makes up the lower part of the brainstem. [1] It is anterior and partially inferior to the cerebellum . It is a cone-shaped neuronal mass responsible for autonomic (involuntary) functions, ranging from vomiting to sneezing . [ 2 ]
Rift Royale is a battle royale game developed by Easy.gg, the developers behind BedWars and Islands. The game was inspired by Fortnite Battle Royale, and was an attempt to create an "awesome competitive game" within the Roblox platforms limitations. In August 2022, the game was shut down following a mass wave of exploiters rendering the game ...
In the medulla oblongata, the arcuate nucleus is a group of neurons located on the anterior surface of the medullary pyramids. These nuclei are the extension of the pontine nuclei. [1] They receive afferents from the corticospinal tract. [citation needed] They in turn project efferents into the cerebellum through the inferior cerebellar ...
The area postrema, a paired structure in the medulla oblongata of the brainstem, [1] is a circumventricular organ having permeable capillaries and sensory neurons that enable its dual role to detect circulating chemical messengers in the blood and transduce them into neural signals and networks.
The ventral portion of the medulla oblongata contains the medullary pyramids. These two ridge-like structures travel along the length of the medulla oblongata and are bordered medially by the anterior median fissure. They each have an anterolateral sulcus along their lateral borders, where the hypoglossal nerve emerges from.
The nucleus ambiguus controls the motor innervation of ipsilateral muscles of the soft palate, pharynx, larynx, and upper esophagus. Lesions of nucleus ambiguus result in nasal speech, dysphagia, dysphonia, and deviation of the uvula toward the contralateral side.
The ventrolateral medulla, part of the medulla oblongata of the brainstem, plays a major role in regulating arterial blood pressure and breathing. It regulates blood pressure by regulating the activity of the sympathetic nerves that target the heart and peripheral blood vessels .
