Neurotransmitters and Their Functions

What is the primary role of neurotransmitters in the nervous system?

• To store energy

• To produce hormones

• To transmit signals between neurons

• To digest food

Which process involves the reabsorption of neurotransmitters by the neuron that released them?

• Degradation

• Synthesis

• Reuptake

• Diffusion

What determines whether Acetylcholine acts as an excitatory or inhibitory neurotransmitter?

• The type of receptor it binds to

• The amount of Acetylcholine released

• The presence of other neurotransmitters

• The temperature of the body

In which part of the brain are dopamine-producing cell bodies primarily located?

• Cortex

• Cerebellum

• Midbrain

• Hippocampus

What effect does low dopamine levels have in Parkinson's disease?

• Slow movements

• Rapid movements

• Hallucinations

• Increased heart rate

Which neurotransmitter is primarily associated with the fight or flight response?

• Serotonin

• Dopamine

• GABA

• Norepinephrine

Low levels of which neurotransmitter are linked to depression?

• Serotonin

• Norepinephrine

• Glutamate

• Dopamine

What is the primary function of GABA in the nervous system?

• To inhibit excessive neuronal activity

• To excite neurons

• To promote digestion

• To increase heart rate

Which neurotransmitter is known for forming strong bonds and trust?

• Serotonin

• Nitric Oxide

• Oxytocin

• Glutamate

What is unique about Nitric Oxide as a neurotransmitter?

• It is a soluble gas

• It is only found in the gut

• It inhibits neuronal activity

• It is stored in synaptic vesicles
