Nervous System

Question 1

Central Nervous System (CNS)

Answer 1

The brain and the spinal cord

Question 2

Peripheral Nervous System (PNS)

Answer 2

Connects brain & spinal cord to rest of the body. Made up of autonomic and somatic

Question 3

Sympathetic Nervous System

Answer 3

Flight or fight response.
Vigorous activity
Releases norepinephrine

Question 4

Autonomic Nervous System

Answer 4

Controls heart & intestines. Made of sympathetic and parasympathetic

Question 5

Somatic Nervous System

Answer 5

Sense organs, connections from CNS to muscles and vice versa

Question 6

Parasympathetic Nervous System

Answer 6

Vegetative state/ non emergency. Low heart rate and high digestive activity. Releases serotonin

Question 7

Hindbrain

Answer 7

Includes: pons, medulla, and cerebellum

Affects support, balance, and coordination

Neurotransmitters: dopamine, norepinephrine, serotonin synthesized in hindbrain.

Question 8

Thalamus

Answer 8

Relay station of sensory info (1st stop) & decides what becomes conscious and what does not go to the cortex.

Input

Question 9

Hypothalamus

Answer 9

Involved in motivated behaviors

4 Fs: food, fornicating, fight, & flight & sleep

Question 10

Basal ganglia

Answer 10

Learning of simple automatic sequences/ habits

Output

Can overpower frontal lobe

Involved in addiction

Answer 13

What pathway (ventral)
Where pathway (dorsal)

Question 14

What/ Ventral pathway

Answer 14

From occipital to temporal lobe. “What is it?” Uses memory

Question 15

Where / Dorsal pathway

Answer 15

From occipital to parietal lobe
Where is it?
Spatial representation

Question 16

Temporal lobe

Answer 16

Auditory and visual memory

Areas:
STG: language, auditory processing 
ITG: object recognition

Answer 21

Deals with behavior

Made of : Dorsolateral, orbitofrontal, and ventrolateral

Question 22

Answer 22

Decision making, working memory, planning

Well connected to parietal lobe
Organization

Upper *

Question 23

Orbitofrontal

Answer 23

Moral judgment, control and understanding of emotions, anticipation of consequences, social norms

Well connected to limbic system and amygdala

*above eyes

Question 24

Answer 24

Inhibition, attention. Reorienting

*lower

Question 25

Insula

Answer 25

Self awareness, regulation of body homeostasis

Question 26

Neglect syndrome

Answer 26

Disorder related to parietal lobe damage. Caused by stroke Cannot see part of the visual field Ie. person only eating half the plate, only copying half of a picture

Question 27

Damage of cerebellum

Answer 27

Ataxia (degeneration) of the cerebellum- look as if intoxicated Could be due to long term use of alcohol
