Neurotransmitters - Edrolo

Question 1

GABA

Answer 1

The most prominent inhibitory neurotransmitter in the nervous system that plays an essential role in motor control and the regulating anxiety. GABA stands for gamma amino butyric acid.

Question 2

Excitatory neurotransmitter

Answer 2

Neurotransmitters that cause a post synaptic Neuron to fire (reach action potential) and hence stimulate a response. The most prominent excitatory neurotransmitter in the Nervous System is glutamate which has a role in memory. Dopamine is another excitatory neurotransmitter important for drive, motivating and motor movement.

Question 3

Inhibitory neurotransmitter

Answer 3

Inhibitory neurotransmitters are those that inhibit a post synaptic neuron from firing and hence inhibit a response.The most prominent inhibitory neurotransmitter in the nervous system is gamma amino butyric acid (GABA). GABA is essential for motor control, vision and decreasing anxiety. Serotonin is another inhibitory neurotransmitter important for stabilising mood.

Question 4

Glutamate

Answer 4

The most prominent excitatory neurotransmitter in the nervous system that plays an essential role in memory formation, learning and movement.

Question 5

Lock and key process

Answer 5

A process in which a neurotransmitter a ects target cells by acting as a ‘key’ by binding to a speci c receptor molecule which acts as ‘lock’.

Question 6

Serotonin

Answer 6

An inhibitory neurotransmitter which plays an important role in stabilising mood.
