Flashcards in CNS and PNS overview pwrpt Deck (24):
1

Telencephalon includes ....

Cerebral hemispheres

2

Diencephalon includes....

hypothalamus and thalamus

3

Mesencephalon includes...

midbrain

4

Metencephalon includes...

Pons and Cerebellum

5

Rhombencephalon includes..

Medulla

6

Five major subdivisions of the forebrain are

Frontal, parietal, occipital, Temporal, Limbic

7

Basal Ganglia important for what?

Smoothing out motor movements of the limbs and axial musculature during body movement.

8

What is the Thalamus involved in?

Relay center for all external sensory information being passed to the forebrain

9

Spinal cord ends at what level

T12 - L1 vertebrae

10

Gray matter located where in the spinal cord?

Centrally

11

White matter located where in the spinal cord

Peripherally

12

Corticospinal (Pyramidal) pathway is motor only

Know it in detail

13

Spinothalamic tract does what

Serves as a sensory pathway for pain and temperature

Know it in detail

14

Where would the cell body of this spinothalamic pathway lie...remember it is sensory.
And what would this cell body look like

Lies in Dorsal Root Ganglion

Pseudounipolar

Know these in detail

15

Posterior Dorsal Column is what

Sensory pathway that informs the brain of the position of body parts in space

16

The Autonomic nervous system is regulated by what>

Hypothalamus and Thalamus

17

Most of the neurons of the autonomic nervous system originate where

Hypothalamus and Thalamus

18

How many Cervical cord segments are there

8

19

How many cervical vertebrae are there?

7...there is one more cervical cord segment than cervical vertebra, this is because the cervical spinal cord segments start before the vertebrae and end below it.

20

Thoracic spinal cord contains how many segments

12

21

Lumbar spinal nerves

5

22

Sacral spinal nerves

5

23

8, 12, 5, 5

cervical, thoracic, lumbar, sacral

24

Autonomic nervous system is regulated by what areas of the brain

Hypothalamus and Thalamus
