  2. Medial lemniscus - Wikipedia

    en.wikipedia.org/wiki/Medial_lemniscus

    The medial lemniscus, also known as Reil's band or Reil's ribbon (for German anatomist Johann Christian Reil), is a large ascending bundle of heavily myelinated axons that decussate in the brainstem, specifically in the medulla oblongata. The medial lemniscus is formed by the crossings of the internal arcuate fibers.

  3. 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 ...

  4. Medial medullary syndrome - Wikipedia

    en.wikipedia.org/wiki/Medial_medullary_syndrome

    Medulla oblongata, shown by a transverse section passing through the middle of the olive. (Medial medullary syndrome can affect structures in lower left: especially #5, #6, #8.) Specialty: Neurology Diagnostic method: Ipsilateral signs and symptoms - flaccid (lmn) paralysis and atrophy of one half of tongue (hypoglossal nerve)

  5. 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 ...

  6. 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.

  7. Olivary body - Wikipedia

    en.wikipedia.org/wiki/Olivary_body

    The inferior olivary nucleus (or 'complex'), which is a part of the olivo-cerebellar system and is mainly involved in cerebellar motor-learning and function. The superior olivary nucleus, considered part of the pons and part of the auditory system, aiding the perception of sound. The inferior olive in itself is divided to 3 main nuclei:

  8. Hypoglossal nucleus - Wikipedia

    en.wikipedia.org/wiki/Hypoglossal_nucleus

    The hypoglossal nucleus is a cranial nerve nucleus, found within the medulla.Being a motor nucleus, it is close to the midline. In the open medulla, it is visible as what is known as the hypoglossal trigone, a raised area (medial to the vagal trigone) protruding slightly into the fourth ventricle.

  9. Medial longitudinal fasciculus - Wikipedia

    en.wikipedia.org/wiki/Medial_longitudinal_fasciculus

    The medial longitudinal fasciculus (MLF) is a prominent bundle of nerve fibres which pass within the ventral/anterior portion of periaqueductal gray of the mesencephalon (midbrain). [1] It contains the interstitial nucleus of Cajal , responsible for oculomotor control, head posture, and vertical eye movement.
