  2. Medulla oblongata - Wikipedia

    en.wikipedia.org/wiki/Medulla_oblongata

    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 ]

  3. Posterior inferior cerebellar artery - Wikipedia

    en.wikipedia.org/wiki/Posterior_inferior...

    A disrupted blood supply to posterior inferior cerebellar artery due to a thrombus or embolus can result in a stroke and lead to lateral medullary syndrome. Severe occlusion of this artery or to vertebral arteries could lead to Horner's Syndrome as well.

  4. Brainstem - Wikipedia

    en.wikipedia.org/wiki/Brainstem

    The medulla oblongata, often just referred to as the medulla, is the lower half of the brainstem continuous with the spinal cord. Its upper part is continuous with the pons. [11]: 1121 The medulla contains the cardiac, dorsal and ventral respiratory groups, and vasomotor centres, dealing with heart rate, breathing and blood pressure.

  5. Lateral medullary syndrome - Wikipedia

    en.wikipedia.org/wiki/Lateral_medullary_syndrome

    Human brainstem blood supply description. PICA is#12. It is the clinical manifestation resulting from occlusion of the posterior inferior cerebellar artery (PICA) or one of its branches or of the vertebral artery, in which the lateral part of the medulla oblongata infarcts, resulting in a typical pattern. The most commonly affected artery is ...

  6. Area postrema - Wikipedia

    en.wikipedia.org/wiki/Area_postrema

    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.

  7. Anterior inferior cerebellar artery - Wikipedia

    en.wikipedia.org/wiki/Anterior_inferior...

    The anterior inferior cerebellar artery (AICA) is one of three pairs of arteries that supplies blood to the cerebellum. It arises from the basilar artery on each side at the level of the junction between the medulla oblongata and the pons in the brainstem .

  8. Cardiovascular centre - Wikipedia

    en.wikipedia.org/wiki/Cardiovascular_centre

    This function is so significant to normal functioning of the circulatory system that the cardiovascular centre is considered a vital centre of the medulla oblongata. [ 2 ] [ 3 ] Hormones like epinephrine and norepinephrine can affect the cardiovascular centre and cause it to increase the rate of impulses sent to the sinoatrial node , resulting ...

  9. Aortic body - Wikipedia

    en.wikipedia.org/wiki/Aortic_body

    The aortic bodies give feedback to the medulla oblongata, specifically to the dorsal respiratory group, via the afferent branches of the vagus nerve (cranial nerve X). [1] [3] The medulla oblongata, in turn, regulates breathing and blood pressure.
