curvature’s effect:
ventral means toward the base or bottom of the brain
dorsal means toward the top or surface of the brain
TEL DIE MES(sen) MET MY
- tel+die = prosencephalon, forebrain
- mes = midbrain
- met+mye = rhombencephalon, hindbrain
, 1: Skull, meninges and vasculature
The skull
the brain is embedded with 3 cranial fossa:
- anterior
- middle
- posterior
sphenoid ridges = divide anterior and middle cranial fossa
petrous ridges of temporal bone = separate the middle and posterior ridges
