1

Cerebrospinal fluid

Clear colorless liquid composed of water protecting brain and spinal cord from injuries

2

Ventricles

4 csf filled cavities within the brain

3

Nuclei

Collection of neuronal cell bodies

4

Medulla respirator center

Adjusts the basic rhythm of breathing

5

Vomitting center

Causes vomiting

6

Deglution center

Swallowing

7

Cardiovascular center

Regulates rate and force of heartbeat

8

Cerebral cortex

Superficial layer of cerebellum

9

Gyri

Folds

10

How is the brain protected?

By skull and cerebral Fluid

11

Describe blood supply to brain

Blood flow to the brain via internal carotid and vertebral arteries

12

Structures of diencephalon

Thalamus, hypothalamus, epithalamus, and 3rd ventricle

13

Structure of brain stem

Medulla oblangata, pons, and mid brains

14

Functions of hypothalamus

Control Ans produce hormones emotional and behavioral patterns regulate eating and drinking control body Temp regulate states of consciousness

15

Blood brain barrier

Tight junction holding together and thick basement membrane surrounding capillaries

16

Function of cerebrospinal Fluid

Shock absorption, maintaining homeostasis, oxygen delivery

17

Sensory areas of cerebral cortex

Touch vision hearing taste smell

18

Associations areas of cerebral cortex

Mental picture recognizing objects faces noises odors and personality

19

Motor areas of cerebral cortex

Voluntary muscle contraction and control speech

20

Function of midbrain

Conveys motor impulses send sensory impulses and regulates auditory/visual reflex

21

Function of reticular formation

Regulates muscle tone alerts of sensory signals response of waking up

Function of thalamus

Relay station for sensory impulses

23

Olfactory

Sensory smell
