Biopsychology- Spine, Brain, Nervous system

Question 1

What is the layout of the nervous system?

Answer 1

Nervous System— Central NS (CNS)- Brain & Spinal cord
/
Peripheral NS (PNS)—- Somatic NS
/
Autonomic NS (ANS)—- Sympathetic NS &
parasympathetic NS

Question 2

What is the main function of the central nervous system?

Answer 2

Integrate sensory info from peripheral NS- regulating the body’s physiological processes & coordinate (un)conscious activity in response to an input

Question 3

What is the main function of the spinal cord?

Answer 3

Relay info between the brain and the rest of the body

Question 4

What are 4 main areas of the brain?

Answer 4

1) Cerebrum
2) Cerebellum
3) Diencephalon
4) Brain stem

Question 5

What is the cerebrum divided up into?

Answer 5

4 lobes, with different primary functions

Question 6

What are the 4 lobes in the cerebrum?

Answer 6

1) Frontal lobe
2) Parietal lobe
3) Occipital lobe
4) Temporal lobe

Question 7

What does the frontal lobe do?

Answer 7

Involved in thought, speech, working memory

Question 8

What does the parietal lobe do?

Answer 8

Processes sensory info (touch, pain, temp etc)

Question 9

What does the occipital lobe do?

Answer 9

Processes visual info

Question 10

What does the temporal lobe do?

Answer 10

Involved in hearing & language comprehension

Question 11

Where are the 4 lobes in the cerebrum?

Answer 11

Frontal= Front top
Parietal= Middle top
Occipital= Back middle
Temporal= Middle bottom

Question 12

What does the diencephalon contain?

Answer 12

1) Thalamus
2) Hypothalamus

Question 13

What does the thalamus do?

Answer 13

Relay station for nerve impulses from senses

Question 14

What does the hypothalamus do?

Answer 14

Regulate body temp, hunger & thirst & links endocrine system and NS

Question 15

Where is the diencephalon?

Answer 15

On top of the brain stem

Question 16

Where is the cerebellum?

Answer 16

Beneath the back of the cerebrum

Question 17

Where is the cerebrum?

Answer 17

The main top bit with the lines in

Question 18

What does the cerebellum do?

Answer 18

Controls motor skills, balance & muscle coordination

Question 19

What are 2 subcomponents of the NS?

Answer 19

1) Central NS
2) Peripheral NS

Question 20

Where is the CNS?

Answer 20

Brain & spinal cord

Question 21

What are 2 subcomponents of the peripheral NS?

Answer 21

1) Somatic NS
2) Autonomic NS

Question 22

What are 2 subcomponents of the autonomic NS?

Answer 22

1) Sympathetic NS
2) Parasympathetic NS

Question 23

What is the function of the somatic NS & what neurons does it have?

Answer 23

Controls voluntary movement of skeletal muscles (limbs)- carries sensory info to & from CNS
Has sensory & motor neurons

Question 24

What is the function of the autonomic NS?

Answer 24

Governs involuntary activities of non-skeletal muscles & internal body systems (heartbeat & digestion0

Question 25

What is the function of the sympathetic NS?

Answer 25

Produces arousal, preparing body for rapid action

Question 26

What are 5 things the sympathetic NS does?

Answer 26

1) Increase HR
2) Dilated pupils
3) Reduces stomach activity
4) Expends energy
5) Fight or flight

Question 27

What is the function of the parasympathetic NS?

Answer 27

Reduces arousal, conserving energy & relaxing the body

Question 28

What are 5 things the parasympathetic NS does?

Answer 28

1) Increase stomach activity
2) Decrease HR
3) Contracted pupils (smaller)
4) Stores glucose
5) Conserves energy
