Biopsychology - Structure and Functions of Neurons

Question 1

What is the function of a Dendrite?

Answer 1

• Where the neurotransmitter receptors are found
• Once the receptor and neurotransmitter bind, it causes an electrical impulse

Question 2

What is the function of the Cell Body?

Answer 2

• Includes the nucleus where the genetic material of the cell can be found

Question 3

What is the function of the Myelin Sheath?

Answer 3

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

Question 4

What is the function of Nodes of Ranvier?

Answer 4

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

Question 5

What is the function of the Axon?

Answer 5

• Sends a nerve impulse through the neuron to transmit a message to the next neuron

Question 6

What is the function of the Terminal Button?

Answer 6

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