Notochord location

WebChordates have a notochord that expands from the animal's head to its tail, towards its back, and dorsal to its digestive region. It has a semi-flexible structure to muscles which help the animal to move. The notochord is developed between the digestive tube and the nerve cord; it provides rigid skeletal support and a flexible location. WebIn the adult brain the location of the neuroporus rostralis corresponds to the lamina terminalis, the neuroporus caudalis to the filum terminale. In defective closures of the rear neuroporus the malformation of a deformity arises known as spina bifida. If the closure of the anterior neuroporus fails to occur an anencephaly results.

WebNotochord remnants may have overlapping features in terms of their location and appearance; however, differen-tiation is crucial because the proper treatment and management may differ drastically. Familiarity with notochord development aids in understanding the characteristic locations of notochordal remnants. Research into the notochord has played a key role in understanding the development of the central nervous system. By transplanting and expressing a second notochord near the dorsal neural tube, 180 degrees opposite of the normal notochord location, one can induce the formation of motor neurons in the dorsal tube. Motor neuron formation generally occurs in the ventral neural tube, while the dorsal tube generally forms sensory cells.
