Nervous System Embryology and Development
Nervous System Embryology and Development of Nervous System is explained. This video provides a comprehensive overview of the neural tube, its subdivisions, and the development of the brain.
Dr. Aizaz from medicovisual.com begins by explaining the formation of the neural tube and its two main parts: the primordial brain and the primordial spinal cord. He then delves into the primary brain vesicles – prosencephalon, mesencephalon, and rhombencephalon – which further divide into secondary brain vesicles.
The video illustrates the craniocaudal folding of the neural tube and highlights the cervical and cephalic flexures. It further explains the development of the pontine flexure and its role in the formation of the metencephalon and myelencephalon.
Dr. Aizaz then details the structures formed by each secondary brain vesicle: the telencephalon giving rise to the cerebral hemispheres and lateral ventricles, the diencephalon forming the thalamus and third ventricle, the mesencephalon becoming the midbrain with the central aqueduct, the metencephalon developing into the cerebellum and pons, and the myelencephalon forming the medulla oblongata. The video concludes by explaining the mnemonic "Today Dixie Miss Met My Spicy Cock" to help viewers remember the order of these structures.
