Lecture 25

Question 1

What are the two types of neurotransmitters?

Answer 1

• Excitatory

- Inhibitory

Question 2

What are examples of Excitatory neurotransmitters?

Answer 2

• Acetcholine

- Glutamate

Question 3

What do excitatory neurotransmitters do?

Answer 3

Cause depolarisation

Question 4

What is an example of Inhibitory neurotransmitters?

Answer 4

GABA

Question 5

What do inhibitory neurotransmitters do?

Answer 5

Causes hyperpolarisation

Question 6

What are the two types of synaptic integration?

Answer 6

• Spatial

- temporal

Question 7

What are the two types of synaptic integration?

Answer 7

• Spatial

- temporal

Question 8

What are the two types of synaptic integration?

Answer 8

• Spatial

- temporal

Question 9

What happens at spatial summation?

Answer 9

Depolarisation from inputs at different spaces travel along the membrane to the axon hillock

Question 10

What happens at temporal summation?

Answer 10

Recieves lots of inputs in a small amount of time

Question 11

What happens at temporal summation?

Answer 11

Recieves lots of inputs in a small amount of time

Question 12

When will the aaction potential be generated?

Answer 12

When the depolarisations reach the threshold potential

Question 13

What are the two types of synaptic networks?

Answer 13

• Divergence

- Convergence

Question 14

What is the divergence network?

Answer 14

One pre-synaptic axon splits to more than 1 axon terminals (different directions from one point)

Question 15

What is the convergence network?

Answer 15

Multiple axons approaching one cell

Question 16

What is the advantage of the divergence network?

Answer 16

It allows control of intensity of a signal

Question 17

What is the advantage of the convergance network?

Answer 17

If one connection is removed, transmission of signal still works
