2. Soma
3. Axon
4. Myelin sheath
5. Axon terminal
6. Synaptic gap

Question 2

Define: dendrite

Answer 2

Receives incoming information

Question 3

Define: soma

Answer 3

The body of the neuron which sends neural impulses down the axon

Question 4

Define: Myeline sheath

Answer 4

Protective case of the axon which aids the speed of neural transmission (MS caused by its deterioration)

Question 5

Define: axon terminal

Answer 5

The points at the end of axons which the chemical substance is released to enable communication between neurons

Question 6

Define: synaptic gap

Answer 6

A microscopic space that neurotransmitters travel across when they are released by one neuron and received by another.
