Honors Peripheral Nervous System

Front

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

Back

The two main divisions are the Sympathetic and Parasympathetic nervous systems.

Front

What is the primary function of the sympathetic nervous system?

Back

The sympathetic nervous system activates the body's fight-or-flight response during high-stress emergencies.

Front

What is the role of the parasympathetic nervous system?

Back

The parasympathetic nervous system promotes the rest-and-digest response, helping to conserve energy and maintain homeostasis.

Front

What type of neurons carry messages away from the central nervous system?

Back

Motor neurons carry messages away from the central nervous system.

Front

What neurotransmitter is used by the somatic nervous system to activate voluntary skeletal muscles?

Back

Acetylcholine (Ach) is the neurotransmitter used to activate voluntary skeletal muscles.

Front

What is the autonomic nervous system responsible for?

Back

The autonomic nervous system is responsible for regulating involuntary bodily functions, including heart rate, digestion, and respiratory rate.

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

What is the function of the motor neurons in the peripheral nervous system?

Back

Motor neurons transmit signals from the central nervous system to muscles, enabling movement.

Front

What is the difference between the somatic and autonomic nervous systems?

Back

The somatic nervous system controls voluntary movements, while the autonomic nervous system regulates involuntary functions.

Front

What physiological changes occur during the activation of the sympathetic nervous system?

Back

Physiological changes include increased heart rate, dilated pupils, and redirected blood flow to muscles.
