Structure And Function Of Neurons

Question 1

1. Dendrites

Answer 1

These are where the neurotransmitter receptors are found
Once the receptor and neurotransmitter bind
Causes a new electrical impulse to occur

Question 2

2. Cell body

Answer 2

Includes the nucleus which contains the genetic material of the cell
provides instructions on the cells job

Question 3

3. Axon

Answer 3

Sends a nerve impulse (action potential) through the neuron to transmit a message to the next neuron

Question 4

4. Myelin sheath

Answer 4

Protects the axon and helps to speed up transmission of the message

Question 5

5. Nodes of Ranvier (the gap)

Answer 5

Speeds up the transmission of the impulse by forcing it to ‘jump’ across the gaps along the axon

Question 6

6. Terminal button (pre synaptic membrane)

Answer 6

The end of the neuron and they send the information through to the next neuron through the release of neurotransmitters
