3.1. The Nervous System Flashcards
1
Q
What are the 4 lobes of the cerebrum?
A
- Frontal
- Temporal
- Occipital
- Parietal
2
Q
What is the frontal lobe responsible for?
A
speech, thought, learning
3
Q
What is the temporal lobe responsible for?
A
hearing, memory
4
Q
What is the occipital lobe responsible for?
A
vision
5
Q
What is the parietal lobe responsible for?
A
sensory info
6
Q
What is the role of the cerebellum?
A
- Controls motor skills/ balance
- If damaged, problems in speech and/or language
7
Q
What makes up the diencephalon?
A
- Thalamus
- Hypothalamus
8
Q
What does the thalamus do?
A
relays nerve impulses from senses to the brain
9
Q
What does the hypothalamus do?
A
- Regulates body temp, hunger and thirst
- Links to the endocrine system
10
Q
What is the role of the spinal cord?
A
- Relays info between the body and the brain to regulate processes and coordinate voluntary movements
- Circuit of cells perform involuntary reflex movements
- If your spinal cord is damaged, nerves below the damage may be cut off and will be unable to function
11
Q
Which nervous systems make up the peripheral nervous system?
A
- Somatic nervous system
- Autonomic nervous system
12
Q
What is the role of the somatic nervous system?
A
- Controls skeletal system and muscles
- Receives info from sensory receptors -> skin/ legs
- Voluntary movement
13
Q
What is the role of the autonomic nervous system?
A
- Controls essential life maintaining processes
- Breathing, heart rate, digestion
- Involuntary movement
14
Q
What is the role of the sympathetic nervous system?
A
- Activated when a threat arises
- AKA fight vs flight
- Noradrenaline/ adrenaline
15
Q
What is the role of the parasympathetic nervous system?
A
- For normal body functioning
- Relaxes body after the emergency has passed
- AKA rest of digestion
- Acetylcholine
