Central Nervous System

Question 1

2. Down axon to terminal button at end of transmitting neurone

Answer 1

3. When impulse reaches button vesicles (sacs where neurotransmitters live) become stimulated

Question 2

3. When impulse reaches button vesicles (sacs where neurotransmitters live) become stimulated

Answer 2

4. Causes release of 1000’s of neurotransmitters

Question 3

4. Causes release of 1000’s of neurotransmitters

Answer 3

5. Neurotransmitters carry message across and into the synaptic gap (between button and dendrite).

Question 4

5. Neurotransmitters carry message across and into the synaptic gap (between button and dendrite).

Answer 4

6. Neurotransmitters are released and bind to the receptor cells (proteins specifically shaped) of the receiving neurone.

Question 5

6. Neurotransmitters are released and bind to the receptor cells (proteins specifically shaped) of the receiving neurone.

Answer 5

7. When enough have attached to the receptor cells, the receiving neurone will fire and the electrochemical is passed on

Question 6

1. Neurone activated by firing produced by action potential-electrochemical signal down axon.

Answer 6

2. Down axon to terminal button at end of transmitting neurone
