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.
medial vestibular nucleus (dorsal or chief vestibular nucleus) medulla (floor of fourth ventricle) corresponding to the lower part of the area acustica in the rhomboid fossa; [citation needed] the caudal end of this nucleus is sometimes termed the descending or spinal vestibular nucleus. This nucleus is sometimes termed the nucleus of Schwalbe.
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 ...
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 ...
The medial vestibular nucleus (Schwalbe nucleus) is one of the vestibular nuclei. It is located in the medulla oblongata . Lateral vestibulo-spinal tract (lateral vestibular nucleus “Deiters”)- via ventrolateral medulla and spinal cord to ventral funiculus (lumbo-sacral segments). ..
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.
Monday’s episode of The Voice was not only marked by mostly pretty damn good Blind Auditions, it might have also given us a sneak preview of Season 26’s finale. Reba McEntire was so determined ...
