Question 6

function of meninges

Answer 6

protection, forms a supporting framework for arteries, veins, and venous sinuses, enclosed fluid filled cavity

Question 7

what makes up the brainstem?

Answer 7

medulla oblongata, pons, and midbrain

Question 8

Medulla oblongata function

Answer 8

conduction pathway for ascending and descending nerve fibers. control center for vital organs (respiration rate, heart rate, vasodilation and constriction), cranial nerves 9-12 are located here

Question 9

Pons

Answer 9

relay center for nerve fibers going from cerebrum and cerebellum.
Plays a role in sleep and respiration
cranial nerve 5 passes through and cranial 6-8 are at the junction of medulla oblongata and pons

Answer 12

cranial nerve I and II

Question 13

Reticular formation

Answer 13

clusters of nuclei scattered throughout stem. play a role in arousing and maintaining consciousness

Question 14

diencephalon

Answer 14

makes up all of the thalamuses

Question 15

what happens in the diencephalon

Answer 15

influences mood and body motions associated with strong emotions, all sensation except olfaction passes through thalamus to get to cerebrum

Question 16

subthalamus

Answer 16

smallest region of thalamus, nuclei have motor functions
