HAP 14: Autonomic Nervous System Review

Front

What is the role of the sympathetic nervous system?

Back

The sympathetic nervous system prepares the body for 'fight or flight' responses during threatening situations, increasing heart rate, dilating pupils, and inhibiting salivation.

Front

What is the role of the parasympathetic nervous system?

Back

The parasympathetic nervous system promotes 'rest and digest' functions, decreasing heart rate, increasing salivation, and enhancing digestion.

Front

What does 'craniosacral' refer to in the context of the autonomic nervous system?

Back

The term 'craniosacral' refers to the parasympathetic division, indicating that its nerve fibers exit the central nervous system near the head (cranial) and the sacral region of the spine.

Front

What is the Autonomic Nervous System (ANS) a part of?

Back

The Autonomic Nervous System is part of the Peripheral Nervous System, which controls involuntary bodily functions.

Front

What physiological response is associated with decreased respiration?

Back

Decreased respiration is primarily associated with the parasympathetic nervous system, which promotes relaxation and restorative processes.

Front

What is the primary neurotransmitter used by the sympathetic nervous system?

Back

The primary neurotransmitter used by the sympathetic nervous system is norepinephrine (noradrenaline).

Front

What is the primary neurotransmitter used by the parasympathetic nervous system?

Back

The primary neurotransmitter used by the parasympathetic nervous system is acetylcholine.

Front

How does the sympathetic nervous system affect heart rate?

Back

The sympathetic nervous system increases heart rate to prepare the body for action.

Front

How does the parasympathetic nervous system affect digestion?

Back

The parasympathetic nervous system enhances digestion by increasing peristalsis and glandular secretions.

Front

What is the 'fight or flight' response?

Back

The 'fight or flight' response is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival, primarily mediated by the sympathetic nervous system.
