Explanation / Answer

please find the answer

a.)Dura mater- outermost menix

b.)Pia mater –middle meninx

c.)Arachnoid mater- structure that project through dura mater into arachnoid mater

d.)First and second ventricles - The lateral ventricles

e. )Aperture -connect to third and fourth ventricle

f )Superior sagittal sinus- collect venous and Cerebrospinal fluid

g )Fourth ventricle -ventrical located between brainstem and cerebellum

h )Cerebral aqueduct- ventricle associated with diencephalon

i )Third ventricle – mennix follow every convotution of brain

j )Arachnoid villus- passageway for cerebrospinal fluid between fourth ventrical and subarachnoid space.

k )Subarachnoid space- located between the arachnoid membrane and pia mater

l )Interventricular foramenia- conncet the lateral ventrical and third ventrical
