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)

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)
