1

Know all the anatomical planes and directions and how they relate to the cortex and brainstem/spinal cord

look at images in book/notes

2

Unilateral

Bilateral

Contralateral

Ipsilateral

One side

Both sides

Oppsoite Side

Same side

3

CNS: brain and _____ :: PNS: ______ nerves & ganglia + ______ nervesganglia

spinal cord

cranial; spinal

4

What are the lobes of the cortex?

Frontal
Parietal
Temporal
Occiptal
(be able to identify)

5

What lobe is involved with motor planning and execution, language abilities and executive functioning?

The frontal Lobe

(think the front= the boss--> plans and executes)

6

What lobe processes somesthetic sensations (pain,temp,touch) from opposite side of body, spatial info, related selected attention and plays a role in language abilites?

the parietal lobe

7

What lobe is responsible for auditory processing and plays a role in semantic memory?

The temporal lobe

8

What lobe is responsible for processing visual info?

The occiptal lobe

9

_______ cortex: higher order processing :: _______ cortex : different regions responsible for sending out commands

Association; Primary

10

___________: first region of the cortex to receive incoming sensory info :: __________ : sends commands to the brainstem and spinal cord for execution of voluntary movements

primary sensory cortex

primary motor cortex

11

the _______ nervous system is made up of cranial and spinal nerves.

Peripheral

12

This artery supplies most of the outer (lateral) surface of the cortex such as the lateral frontal, temporal, parietal, and occipital cortex as well as the perisylvian language zone. It also supplies some deep inner structures such as the internal capsule and much of the basal ganglia.

The Middlle Cerebral Artery (MCA)

13

This artery supplies the medial frontal lobe, medial parietal lobe, and the ventral anterior frontal lobe.

The Anterior Cerebral artery (ACA)

14

This artery supplies the lower lateral surface of the temporal lobes, the lateral and medial surface of the occipital lobes, and portions and the thalamus.

Posterior Cerebral Artery (PCA)

15

Muscles of the limbs: _________ innervation :: muscles of the head and neck : _________ innervation

unilateral contralatera; bilateral

16

Upper motor neurons originate in the _______ and terminate /synapse on LMN's in either the _______or in the brainstem.

cortex; spinal cord

17

All UMN cross over to the ________ side before synapsing on LMN.

opposite

18

LMN originate in _______ or brainstem and terminate on the _______ they innervate.

spinal cord; muscles

19

All sensory information, except smell, passes through the _______ before reaching the cortex.

thalamus

20

Where are ganglia located?

Outside of the CNS

21

a collection of nerve cell bodies outside the central nervous =

ganglia

22

What two tracts make up the pyramidal system?

The corticospinal and corticobulbar

23

The ______ and ______ tracts are responsible for the execution of voluntary movements.

The corticospinal and corticobulbar

24

Where does the corticospinal tract originate?

It begins in the cerebral cortex

25

Where does the corticospinal tract decussate?

It decussates at the pyramids in the lower medulla

26

Where does the corticospinal tract terminate?

At different levels of the spinal cord

27

Where does the corticobulbar tract originate?

It begins in the cerebral cortex

28

Where does the corticobulbar tract terminate?

It terminates at different cranial nerve nuclei located at different levels of the brainstem

29

Where do the corticobulbar tracts cross over?

They cross over at the level of the cranial nerve nuclei that they innervate

30

All the muscles of the head and neck are innervated by what tract?

The corticobulbar tract

31

The extrapyramidal system can be subdivded into what 2 systems?

-indirect activation pathway
-control circuits: basal ganglia & cerebellum

32

Corticobulbar tracts innerve ______ motor neurons.

Upper

nuclei; brainstem

ganglia; brainstem
