  2. Anterolateral sulcus of medulla - Wikipedia

    en.wikipedia.org/.../Anterolateral_sulcus_of_medulla

    The anterolateral sulcus (or ventrolateral sulcus) is a sulcus on the side of the medulla oblongata between the olive and pyramid. The rootlets of the hypoglossal nerve (CN XII) emerge from this sulcus.

  3. Medullary pyramids (brainstem) - Wikipedia

    en.wikipedia.org/wiki/Medullary_pyramids_(brainstem)

    They each have an anterolateral sulcus along their lateral borders, where the hypoglossal nerve emerges from. Also at the side of each pyramid there is a pronounced bulge known as an olive. Fibers of the posterior column, which transmit sensory and proprioceptive information, are located behind the pyramids on the medulla oblongata.

  4. Hypoglossal nucleus - Wikipedia

    en.wikipedia.org/wiki/Hypoglossal_nucleus

    The hypoglossal nucleus is located between the dorsal motor nucleus of the vagus and the midline of the medulla. Axons from the hypoglossal nucleus pass anteriorly through the medulla forming the hypoglossal nerve which exits between the pyramid and olive in a groove called the anterolateral sulcus.

  5. 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 ]

  6. Olivary body - Wikipedia

    en.wikipedia.org/wiki/Olivary_body

    Each olivary body is located on the anterior surface of the medulla lateral to the pyramid, from which it is separated by the antero-lateral sulcus and the fibers of the hypoglossal nerve. Behind ( dorsally ), it is separated from the postero-lateral sulcus by the ventral spinocerebellar fasciculus .

  7. Hypoglossal nerve - Wikipedia

    en.wikipedia.org/wiki/Hypoglossal_nerve

    The hypoglossal nerve arises as a number of small rootlets from the front of the medulla, the bottom part of the brainstem, [1] [2] in the anterolateral sulcus which separates the olive and the pyramid. [3] The nerve passes through the subarachnoid space and pierces the dura mater near the hypoglossal canal, an opening in the occipital bone of ...

  8. 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.
