Medulla oblongata is derived from ?
Ans. is d i.e., MyelencephalonNervous system develops from ectoderm (neuroectoderm). Nervous system develops from neural tube which in turn develops by process of neurulation, i.e. formation of neural plate and its infolding into neural tube. Structures formed from neural tube are :?A) From cranial pa (enlarged cephalic pa)Gives rise to brain. Developmental pas are :i) Forebrain (prosencephalon)Telencephalon : Cerebral hemisphere and lateral ventricle.Diencephalon : Optic cup and stalk (gives rise to retina), pituitary, thalamus, hypothalamus, epithalamus, pineal gland, and third ventricle.ii) Midbrain (mesencephalon)Cerebral aqueduct.iii) Hindbrain (rhombencephalon)Metencephalon : Cerebellum, ponsMyelencephalon Medulla oblongataB) From caudal paGives rise to spinal cord.
