Structure of A Neuron

Question 1

Dendrites

Answer 1

Are the bushy branches at the receiving end of a neuron. During neural communication, the end of the dendrites, known as receptor sites, receive the neural message before it is sent to the cell body (soma) for processing

Question 2

Axon

Answer 2

The axon is the long stick-like part of the neuron that extends down from the body of the cell to the end. It is responsible for transmitting the electrical impulse down from the receiving end of the neuron to the sending end.

Question 3

Myelin

Answer 3

The myelin of a neuron is the fatty and protein substances that looks like small fatty bubbles along the axon. It functions to insulate the neuron, which helps to protect the axon and the insulates the messages from interference. This also importantly helps to increase the speed of the electrical impulse from one end of the neuron to the other.

Question 4

Axon terminals

Answer 4

The axon terminals are the sending end of the neuron, meaning they are responsible for the release of the neural message (in the form of chemicals) into the synapse. This is enabled by conducting electrical energy away from the cell body and sending it down the neuron
