These types have an stimulating effect on the neurons. it will increase the likelihood that the neuron will fire action potential

• Inhibitory

• Excitatory

GABA is a

• Excitatory

• Inhibitory

This is produced in stressful situations

• Adrenaline

• Serontin

• Dopamine

• Glutamate

It is important in controlling mood and can affect the happiness levels of an individual.

• Serontin

• Dopamine

• Adrenaline

• GABA

Match the following

• excitatory ,too much = high blood Pressure

• GABA

• Involved in muscle movement and memory

• Endorphins

• It is important in controlling mood and

• Acetylcholine

• Regulates communication between brain cells

• Serotonin

• Known as the 'feel-good' neurotransmitter

• Dopamine

Organize these options into the right categories

Groups:

(a) Excitatory

,

(b) Inhibitory

• Acetylcholine

• GABA

• Acetylcholine

• Norepinephrine

• Norepinephrine

• Serotonin

• Dopamine

• Glutamate

supports cognitive functions such as memory formation and learning. This is known as the most abundant neurotransmitter, which is found in the central nervous system.

• Norepinephrine

• Glutamate

• GABA

• Serotonin

It is especially prevalent during the fight-or-flight response, aiding in alertness.

• GABA

• GLUTAMATE

• Norepinephrine

• DOPAMINE

Only certain neurotransmitters can unlock a message channel in certain receptors in the post-synaptic neuron This is called

Communication between neurons can be described as a lock-and-key process. This is because the

• lock-and-key process refers to the specific interaction between neurotransmitters and receptors.
• lock-and-key process is only applicable to muscle cells, not neurons.
• lock-and-key process is a metaphor and not a scientific concept.
• lock-and-key process involves electrical signals instead of chemical interactions.
