Detailed Internal Structure of Medulla Oblongata

This video provides a very detailed description of internal features of medulla oblongata using easy sketches. The video starts with general overview and orientation of medulla oblongata. Later on, it explains the structures present at levels of decussation of pyramids, level of decussation of lemnisci, also known as the great sensory decussation, and the level of olives. This video emphasizes on various nuclei and tracts present at each level of medulla as well as the nerves emerging from medulla. At the end, it clinically correlates medullary disorders and its manifestations. 0:15 Overview 1:01 Pyramids 2:08 Level of decussation of pyramids 3:51 Arcuate nucleus 4:20 Level of the olives 7:03 Nucleus gracilis and cuneatus 9:17 Levels of great sensory decussation 10:15 Trigeminal nuclei 12:05 Anterior spinocerebellar tract 13:43 Spinothalamic tract 15:05 Spinal lemniscus 15:52 Vestibulocochlear nuclei 17:22 Nucleus ambiguus 18:02 Reticular formation 18:21 Hypoglossal nucleus 18:48 Dorsal vagus nucleus 19:18 Tractus solitarius 20:14 Medial longitudinal fasciculus 20:43 Tectospinal tract 21:44 Clinical correlation
