What is the role of sympathetic nerves in the autonomic nervous system?

Back

Sympathetic nerves prepare the body for 'fight or flight' responses, such as dilating pupils and increasing heart rate.

Front

True or False: The autonomic nervous system's sympathetic division is responsible for increasing heart rate during stressful situations.

Back

True

Front

What branch of the nervous system does the autonomic nervous system belong to?

Back

The autonomic nervous system is a branch of the peripheral nervous system.

Front

What is the function of parasympathetic nerves in the autonomic nervous system?

Back

Parasympathetic nerves promote 'rest and digest' functions, such as stimulating digestion and slowing the heart rate.

Front

What term describes the phenomenon where most vital organs receive instructions from both sympathetic and parasympathetic divisions?

Back

Dual innervation.

Front

What is the primary function of the autonomic nervous system?

Back

The autonomic nervous system regulates involuntary bodily functions, including heart rate, digestion, and respiratory rate.

Front

What are the two main divisions of the autonomic nervous system?

Back

The two main divisions are the sympathetic division and the parasympathetic division.

Front

How do sympathetic and parasympathetic divisions work together?

Back

They work together to maintain homeostasis by balancing the body's responses to stress and relaxation.

Front

What physiological changes occur during a sympathetic response?

Back

Increased heart rate, dilated pupils, and inhibited digestion.

Front

What physiological changes occur during a parasympathetic response?

Back

Decreased heart rate, constricted pupils, and stimulated digestion.
