Flashcards in Chapter 3 pt.3 Deck (42):
1

What makes communication between cells possible?

neurotransmitters

2

What determines whether an NT will bind to a cell?

It's shapes/chemical composition

3

List the different type of neurotransmitters?

1. acetylcholine
2. serotonin
3. Norepinephrine
4. Dopamine

4

Which neurotransmitter is this: deals with movement

acetylcholine

5

Which neurotransmitter is this: deals with sleep & wakefulness. When this is low it can lead to depression.

serotonin

6

Which neurotransmitter is this: when this is low it can lead to depression.

norepinephrine

7

Which neurotransmitter is this: when this is low it can lead to schizophrenia or Parkinson's disease.

dopamine

8

Which neurotransmitter is this: changes underlie effects of cocaine and amphetamines

dopamine & norepinephrine

9

Why do certain drugs have an effect on us?

because their structure haas the same shape as an NT and can modify neuronal transmission!

10

What section of the brain is influenced by sedatives and alcohol?

GABA

11

What plays a role in the effects of narcotics?

Opiate receptors & dopamine

12

Structure of Nervous System: what are the two main sections of the nervous system?

1, Central Nervous System
2. Peripheral nervous system

13

Structure of Nervous System: what does the central nervous system consist of?

1. brain
2. spinal cord

14

Structure of Nervous System: what two systems are under the peripheral nervous system?

1. Somatic nervous system
2. autonomic nervous system

15

Structure of Nervous System: what are the two systems under the autonomic nervous system?

1. sympathetic nervous system
2. parasympathetic nervous system

16

Structure of the brain: what are the three main sections of the brain?

1. hindbrain
2. midbrain
3. forebrain

17

Structure of the brain: what are the structures of the hindbrain?

medulla
pons
cerebellum

18

Structure of the brain: which part of the hindbrain is responsible for breathing & circulation?

medulla

19

Structure of the brain: which part of the hindbrain is responsible for sleep and arousal?

pons

20

Structure of the brain: which part of the hindbrain is responsible for coordination of movement and sense of equilibrium

cerebellum

21

What is the first area of your brain affected by alcohol (not GABA)?

cerebellum

22

Structure of the brain: which section (of the three main sections) brain uses integration of sensory inputs?

midbrain

23

Structure of the brain: in the midbrain what to structures contribute to the integration of sensory inputs?

- inferior colliculus (auditory)
- superior colliculus (visual)

24

Structure of the brain:
In the midbrain which is responsible for auditory and visual senses, respectively.
1. inferior colliculus (________)
2. superior colliculus (_______)

inferior colliculus (auditory)
superior colliculus (visual)

25

Structure of the brain:
In the midbrain which is responsible for auditory and visual senses, respectively.
1. _________ colliculus (auditory)
2. _________ colliculus (visual)

1. inferior
2. superior

26

Structure of the brain: In the midbrain, what does the substantia Nigra do?

dopamine projections originate here

27

Structure of the brain: depletion of neurons in the Substantia Nigra causes __________

Parkinson's
