1

Central Nervous System

Brain & spinal cord

2

Peripheral nervous system

Everything outside CNS
-somatic
-autonomic

3

Somatic nervous system

Bring info in and output to motor movements (skeletal muscles)
VOLUNTARY mvmt

4

Autonomic NS divisions

-sympathetic
-parasympathetic
-enteric

SMOOTH muscle

5

Sympathetic NS

Fight or flight

-synapses in ganglia-->organs

6

Parasympathetic NS

Rest and digest

-synapses straight to organs

7

Enteric NS

"Brain in your gut"
-maintains smooth muscle of gut
*Human Microbiome Project (HMP)

8

Rostral

Towards front end
(Towards face)

9

Caudal

Towards back/tail
(Toward back of head)

10

Dorsal

Towards top
(Top of head)

11

Ventral

Towards bottom/belly
(Towards feet)

12

Medial

Towards midline

13

Lateral

Away from midline

14

Forebrain

Telencephalon
Diencephalon

15

Midbrain

Mesencephalon

16

Hindbrain

Metencephalon
Myelencephalon

17

Nucleus

Cluster of neurons INSIDE CNS that perform similar function

18

Ganglia

Cluster of neurons OUTSIDE CNS that perform a similar function

19

Brain stem

Myelencephalon
Metencephalon
Mesencephalon
Diencephalon

20

Lateral ventricle

Telencephalon

21

Third ventricle

Diencephalon

22

Cerebral Aquaduct

Mesencephalon

23

4th ventricle

Metencephalon
Myelencephalon

24

Central canal

Caudal part of neural tube

25

Medulla

-Within Myelencephalon
-Contains nucleus of the solitary tract (NTS
-function: mediates many things (taste, hearing, balance, face/neck muscles) AND regulate BP/respiration/digestion

26

Nucleus of the solitary tract

Part of the medulla
Receives input from Vagus nerve

27

Cerebellum

-Within Metencephalon
-"Little brain"
-FUNCTION: compare what brain tells muscle to do and what it actually does

28

Pons

-Within metencephalon
-many crossings of fibers going to cerebellum
-contains locus coeruleus

29

Locus Coeruleus

Within the pons
*Major NOREPINEPHRINE circuit
(Reinforcement and arousal)

30

Central gray

Within Mesencephalon
Important in pain
