Part 2 Nervous System - Structure of a neuron

Question 1

What are neurons?

Answer 1

Neurons are specialized cells and nerve cells for communication

Question 2

How do neurons connect with each other?

Answer 2

Through neural networks

Question 3

What are the 6 structures that form a neuron?

Answer 3

• nucleus (contains genetic info)
• soma
• dendrites
• myelin
• axon
• axon terminals

Question 4

What is the function of the dendrites?

Answer 4

The dendrites receive information from other neurons which they carry from the synapse to the soma

Question 5

What is the function of the soma?

Answer 5

The soma controls the metabolism and maintenance of the neuron

Question 6

What is the function of the myelin?

Answer 6

The myelin is a white coating of fatty insulation covering the axon, it facilitates the transmissions passing through the axon

Question 7

What is the purpose of the axon?

Answer 7

It is the long fiber that carries information away from the cell

Question 8

What is the purpose of the Axon terminal?

Answer 8

The axon terminal discharges neurotransmitters that will travel through the synapse and connect with the dendrites of the post -synaptic neuron

Question 9

How is information transmitted between neurons?

Answer 9

Info is transmitted electrically within a neuron, and chemically through the synapses between neurons

Question 10

In what direction do the electrical impulses travel through the neuron?

Answer 10

From left to right

From the dendrites to axon-terminals
