1

What is the most energy demanding tissue in the body?

Central Nervous System

2

The cerebral aterial circle is also known as:

Circle of Willis

3

In which species do we find Rete Mirabile, a modification of the internal carotid arteries?

Feline, ruminant, porcine

4

What are the 3 main arteries that supply the brain?

2 internal carotid arteries and 1 basilar artery

5

The _________ artery is the result of the union of bilateral vertebral arteries after they pass into the braincase

basilar artery

6

What is the name for the space created by dural reflections of the meninges?

dural sinuses

7

What is the primary blood supply to the spinal cord?

ventral spinal artery

8

What is the secondary blood supply to the spinal cord?

dorsal spinal arteries

9

What is the venous system within the epidural space?

Internal verterbral venous plexus

10

What is the deepest layer of the meninges?

Pia mater

11

What is the middle layer of the meninges?

arachnoid layer (mater)

12

___________ is between the arachnoid layer and pia mater; contains CSF

subarachnoid space

13

The ____________ is located in the pia mater of the spinal cord and connects the pia mater to the arachnoid and dura mater

denticulate ligament(s)

14

What are the two layers of the dura mater of the cranial meninges?

periosteal & meningeal

These two layers separate to create the dural sinuses

15

Is production of CSF an active or passive process?

ACTIVE.

16

What is hydrocephalus?

When excessive accumulation of CSF results in an abnormal widening of the ventricles

17

Lesions associated with the visual cortex of the occipital lobe may produce __________

cortical blindness

18

Which lobe is responsible for perception and innervation of visual information?

occipital lobe

19

Which lobe integrates sensory information to produce a 3D "map" of the body's location in space and its relation to objects in that space?

parietal lobe

20

Unilateral lesions of the parietal globe produce:

hemineglect

21

Which lobe contains sensory and motor cortices with regions that plan and initiate movement?

frontal lobe

22

Which lobe is responsible for perception and interpretation of olfactory information?

piriform lobe

23

Lesions of which lobe result may result in loss of smell?

piriform lobe

24

Which lobe is responsible for perception and interpretation of auditory information?

temporal lobe

25

True or false: Destruction of the left auditory cortex will result in deafness in the right ear.

False.

It won't result in deafness in either ear. Multiple decussations allow info from both cochlea to reach both auditory cortices.

SO, both auditory cortices must be destroyed for deafness to occur

26

Which portion of the limbic system is responsible for homeostasis and circadian rythym?

hypothalamus

27

Which portion of the limbic system is responsible for emotional memory (ex: signs of fear even if auditory cortex is damaged)

amygdala

28

Which portion of the limbic system is responsible for converting short term memory to long term memory?

hippocampus

29

Which portion of the limbic system is responsible for emotional behavior and conscious proprioception?

thalamus

30

Functions to arouse the cortex; controls consciousness and requires a functional cortex:

ARAS

Ascending Reticular Activating System
