Question 3

Special connective tissues that cover brain

Answer 3

Meninges

3 layers of meninges

Answer 4

Dura mater (superficial; tough mother); Arachnoid mater (spider like); Pia Mater (directly on top of brain; delicate)

Question 5

Subdural space

Answer 5

in between dura mater and Arachnoid mater; where venous structures drain blood from brain

Question 6

Answer 6

Subarachnoid space, & brain ventricles; produced by choroid plexuses in lateral ventricles and released by ciliated ependymal cells (also found in central canal of spinal cord)

Question 6

Organization of brain

Answer 6

Superficial gray matter (cerebral cortex) -> intermediate white matter -> deep gray matter (basal nuclei)

Answer 7

in between Arachnoid mater and pia mater; cerebral spinal fluid
