Neural transmittion

Question 1

define neural transmisstion

Answer 1

the tranfer of information between neurons

Question 2

define dendrite

Answer 2

the finger like cells found on the end of a neuron, they are receiving or input portions of a neuron

Question 3

define axon

Answer 3

the portion of a nerve cell that carries nerve impulses away from the cell body

Question 4

define cell body

Answer 4

the speherical part of the cell that contains the nucleus

Question 5

define synapse

Answer 5

the gap between the neurons is called a synapse

Question 6

steps to neural transmission

Answer 6

densdrites recive an chemical signal, which is then converted into an electrical signal. This is sent through the cell body donw to the axon. This electrical impulse travels donw the axon assisted by the mylin sheath until it reaches the axon terminal. This is where it is converted into a chemical signal in the form of a neurotransmitter to continue ots journey.

Question 7

define neurotransmitters

Answer 7

chemicals that pass across the synapse triggering an action potential in the next neuron

Question 8

effect of neurotransmitters

Answer 8

• seritonin
• dopamine

Answer 9

it regulate mood, anxiety, appetite, sleep cycle and body tempertaure and low levels can lead to depression
