1

Central Nervous System

Responsible for thought, perception, feeling and autonomic body functions
(Brain, brainstem, spinal cord)

2

Peripheral Nervous System

Responsible for transmitting commands from the brain to the body and receiving feedback from the body
(Cranial Nerves, peripheral Nerves)

3

Efferent Nerves

Leave the brain and convey commands to other parts of the body

4

Afferent Nerves

Send signals to the brain

5

Diencephalon

Filters unneeded information before reaching cerebral cortex

6

Midbrain

Responsible for regulating LOC, including patterns of sleep and wakefulness

7

Brainstem

Controls pulse, pressure, and respiratory rate and pattern

8

Pons

Controls respiratory rate and depth

9

Medulla Oblongata

Controls pressure and pulse rate

10

Limbic System

Where rage and anger are generated

11

Hypothalamus

Where pleasure, thirst and hunger are found

12

Pituitary Glands

Receives information from the hypothalamus and then sends chemical to the adrenal glands to release epi and norepi

13

Adrenal Glands

Release epinephrine and norepinephrine

14

Cerebellum

Manages complex motor activity unconsciously (tree of life)

15

Synapse

Connects to the cell by chemicals called neurotransmitters. Doesn't physically touch the nerve cell

16

Neurotransmitter

Dopamine, acetylcholine, epinephrine, serotonin
These chemicals send signals from one nerve cell to the other

17

Axon

Bridge that connects the synapse to the nucleus

18

Myelin

A sheath that surrounds the nerve cell allowing the cell to transmit its signal consistently without "shorting out"

19

Vitals for Increased Intercranial Pressure

Decreased HR, Decreased RR, Increased BP

20

Trismus

Clenched teeth

21

Ptosis

Drooping, sagging, or prolapse of a part of the body
(Bell palsy, stroke)

22

Coma

State where patient does not respond to painful stimuli

23

Supra orbital Foramen

Notch near bridge of nose used to elicit pain

24

Decorticate Posturing

Contractions of arms towards their chest and point their toes
Indicative of damage directly below cerebral hemisphere

25

Decebearate Posturing

Contract arms and wrists outwards and point their toes
Indicative of damage near the brainstem

26

GCS

Eyes Opening-
4 Spontaneous
3 Voice
2 Pain
1 None
Verbal-
5 Oriented
4 Disoriented
3 Innapropiate Words
2 Incompetent
1 None
Motor-
6 Obeys
5 Localizes
4 Withdraws
3 Decorticate
2 Deceberate
1 None

27

Hallucinations

Hear voices, see snakes, feel insects, all that are within their mind

28

Delusions

Thoughts or perceived abilities that are not based on reality

29

Psychosis

Patient can not tell what is real or inside his mind

30

Corneal Reflex

Tap between the eyes to determine gag reflex
