Biological Psychology

Question 1

What are the four lobes of the brain?

Answer 1

• Frontal lobe
• Parietal lobe
• Occipital lobe
• Temporal lobe

Question 2

Where is the frontal lobe?
What is it’s function?

Answer 2

Behind forehead.
Controls person’s behaviour, personality and emotions and is involved in intellectual activities such as planning and organisation

Question 3

Where is the temporal lobe?
What is it’s function?

Answer 3

Behind the ears. Bottom of brain
Holds the bulk of our memories and our ability to understand and speak

Question 4

Where is the parietal lobe?
What is it’s function?

Answer 4

Top of the brain.
Responsible for our perception and special awareness as well as manipulating objects and spelling.

Question 5

Where is the occipital lobe?
What is it’s function?

Answer 5

Back of the brain.
Responsible for sight.

Question 6

What does the cerebellum control?

Answer 6

Muscle movement, balance and coordination

Question 7

What does the brain stem include?
What does it control?

Answer 7

Midbrain, medulla, pons.
Controls breathing, heart rate, consciousness, blood circulation, basic motor responses. Relays sensory information and regulates sleep-wake cycle.

Question 8

What is neurotransmission?

Answer 8

Process by which one neurone communicates with another

Question 9

What are neurotransmitters?

Answer 9

Chemicals that pass messages between neurones.

Question 10

What are vesicles?

Answer 10

Tiny sacs containing molecules of neurotransmitter chemicals

Question 11

How does synaptic transmission occur?

Answer 11

• action potential reaches end of pre-synaptic neurone
• triggers the release of neurotransmitters from vesicles
• neurotransmitters diffuse across synapse
• at the dendrite in post-synaptic neurone , neurotransmitters bind to to receptors
• chemical message converted back to electrical impulse and continues to the next neurone
• the neurotransmitters are reabsorbed into pre- synaptic neurone

Question 12

ORDER THE STATEMENTS:

1 - this triggers the release of neurotransmitters from vesicles (which merge with membrane to open
2 - chemical message converted back to electrical impulse and the message continues to the next neurone in the chain
3 - neurotransmitters diffuse across synapse
4 - the neurotransmitters are then reabsorbed back into pre- synaptic neurone
5 - at the dendrite in the neighbouring neurone, the neurotransmitters bind to to receptors in the post-synaptic neurone
6 - electrical impulse (action potential) reaches terminal buttons at the end of the pre-synaptic neurone
