Front

Which neurotransmitter is known for its inhibitory effects and helps regulate anxiety and stress?

Back

Front

What neurotransmitter is primarily associated with feelings of pleasure and reward?

Back

Dopamine is the neurotransmitter commonly associated with feelings of pleasure and reward.

Front

What is the function of the somatic nervous system?

Back

The somatic nervous system controls voluntary movements and transmits sensory information to the central nervous system.

Front

What is the role of the autonomic nervous system?

Back

The autonomic nervous system regulates involuntary bodily functions, such as heart rate and digestion.

Front

What are the two branches of the autonomic nervous system?

Back

The autonomic nervous system has two branches: the sympathetic and parasympathetic nervous systems.

Front

What is the function of the sympathetic nervous system?

Back

The sympathetic nervous system prepares the body for 'fight or flight' responses during stressful situations.

Front

What is the role of the parasympathetic nervous system?

Back

The parasympathetic nervous system promotes 'rest and digest' activities, conserving energy and promoting relaxation.
