  2. Medial medullary syndrome - Wikipedia

    en.wikipedia.org/wiki/Medial_medullary_syndrome

    Medial medullary syndrome, also known as inferior alternating syndrome, hypoglossal alternating hemiplegia, lower alternating hemiplegia, [1] or Dejerine syndrome, [2] is a type of alternating hemiplegia characterized by a set of clinical features resulting from occlusion of the anterior spinal artery.

  3. Medulla oblongata - Wikipedia

    en.wikipedia.org/wiki/Medulla_oblongata

    Blood to the medulla is supplied by a number of arteries. [3] Anterior spinal artery: This supplies the whole medial part of the medulla oblongata. Posterior inferior cerebellar artery: This is a major branch of the vertebral artery, and supplies the posterolateral part of the medulla, where the main sensory tracts run and synapse. It also ...

  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. Reticular formation - Wikipedia

    en.wikipedia.org/wiki/Reticular_formation

    The medial reticular formation and lateral reticular formation are two columns of nuclei with ill-defined boundaries that send projections through the medulla and into the midbrain. The nuclei can be differentiated by function, cell type, and projections of efferent or afferent nerves.

  6. Medullary pyramids (brainstem) - Wikipedia

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

    Having crossed over at the middle line, they pass down in the posterior part of the lateral funiculus as the lateral corticospinal tract. The other 10% of the fibers stay uncrossed in the anterior corticospinal tract. The pyramidal decussation marks the border between the spinal cord and the medulla oblongata. [1]

  7. Raphe nuclei - Wikipedia

    en.wikipedia.org/wiki/Raphe_nuclei

    However, studies also show feedback loops from numerous areas of the brain controlling the serotonergic neurons located in the nucleus raphe dorsalis, including the orbital cortex, cingulate cortex, medial preoptic area, lateral preoptic area, and several areas of the hypothalamus.

  8. Corticospinal tract - Wikipedia

    en.wikipedia.org/wiki/Corticospinal_tract

    The lateral corticospinal tract neurons cross the midline at the level of the medulla oblongata, and controls the limbs and digits. [1] [3] The lateral tract forms about 90% of connections in the corticospinal tract; [2] the vast majority cross over in the medulla, while the rest (about 2-3%) remain ipsilateral. The anterior corticospinal tract ...

  9. Internal arcuate fibers - Wikipedia

    en.wikipedia.org/wiki/Internal_arcuate_fibers

    Upon decussation (crossing over) from one side of the medulla to the other, also known as the sensory decussation, they are then called the medial lemniscus. The internal arcuate fibers are part of the second-order neurons of the posterior column-medial lemniscus system , and are important for relaying the sensation of fine touch and ...
