Question:
Describe the development of the different parts of the neurocranium(brain case)-(Chondrocranium)
Author: Nontoe NonoeAnswer:
-The chondrocranium portion of the neurocranium initially develops as several separate cartilage models which ossify and fuse together over time through endochondral ossification -The bones rostral (i.e. anterior) to the sella turcica are called the prechondral chondrocranium and derive from neural crest cells which have migrated here during earlier development -The bones caudal to the sella turcica are called the chondral chondrocranium and derive from the paraxial mesoderm in the region -These segments ossify relatively early in life and are thus expected to be affected more by genetic influences than the environment. -
