Medulla oblongata, simplified sections of internal structure

This video is part of a playlist of videos on the internal structure of the brain stem. The playlist uses simplified sketches that are gradually drawn for the purpose of description. Internal structure at the following section levels is described: Level of the inferior olivary nucleus (open medulla) Level of medial lemniscal decussation (closed medulla) Level of the decussation of pyramids (closed medulla) Spinal cord For each fiber tract the location, function, origin and destination are summarized. Each nucleus is identified in terms of location, function and connections. Thus the session correlates anatomical structures seen in the medulla with those of the pons, midbrain and spinal cord. For this purpose, a section of the spinal cord has also been added. 00:00 Introduction 01:00 The pyramids – corticospinal fibers 03:50 Arcuate nucleus 04:20 Olive and inferior olivary complex 05:05 Cerebellar peduncles 06:09 Cranial nerves emerging from the medulla oblongata 06:39 Fasiculus and nucleus gracilis and cuneatus 09:17 Decussation of the medial lemniscus 10:14 Spinal nucleus and tract of the trigeminal nerve 11:24 Anterior and posterior spinocerebellar fibers 13:43 Spinothalamic fibers 15:31 Spinotectal tract 15:52 Vestibulocochlear nuclei 17:21 Nucleus ambiguus 18:02 Reticular formation 18:21 Hypoglossal nucleus 18:46 Dorsal nucleus of the vagus nerve 19:17 Nucleus of the tractus solitarius 20:14 Medial longitudinal fasciculus 20:43 Tectospinal tract 21:17 Extrapyramidal fibers 21:43 Lateral medullary syndrome 22:58 Medial medullary syndrome After completion of this video session, it is expected that you will be able to Develop a three-dimensional picture of the gross anatomy of the medulla oblongata and its internal structure. Locate the positions of cranial nerve nuclei and the paths taken by the major ascending and descending nerve tracts Assess the signs and symptoms presented by the patient and identify the exact location of a lesion affecting the brain stem. Correlate the signs and symptoms of medial and lateral medullary (Wallenberg) syndromes with the nuclei and nerve tracts involved by the vascular lesions.
