Human Brain Divisions
Ans: cerebrum, brainstem, diencephalon, cerebellum
Quiz What protects the brain?
Ans: skull, meninges, and BBB
Quiz Ventricles of the brain
Ans: cavities within the brain filled with cerebrospinal fluid; 2 lateral, 3rd ventricle, 4th ventricle
Quiz Meninges
Ans: 3 layers of connective tissue that cover and protect the CNS organs and enclose CSF.
Quiz Dura Mater
,Ans: thick, outermost layer of the meninges surrounding and protecting the brain and spinal cord
Quiz pia mater
Ans: the delicate innermost membrane enveloping the brain and spinal cord.
