Flashcard on the Nervous System

Front

What is the autonomic nervous system responsible for?

Back

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

Front

What is NOT a function of the autonomic nervous system?

Back

Voluntary muscle movement is NOT regulated by the autonomic nervous system; it is controlled by the somatic nervous system.

Front

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

Back

The two main divisions are the sympathetic nervous system and the parasympathetic nervous system.

Front

What is the primary function of the sympathetic nervous system?

Back

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

Front

Which hormone is primarily associated with the 'fight or flight' response?

Back

Epinephrine (also known as adrenaline) is the primary hormone released during the 'fight or flight' response.

Front

Where do sympathetic nervous system (SNS) cell bodies originate in the spinal cord?

Back

SNS cell bodies originate in the thoracic and lumbar regions of the spinal cord.

Front

What is the role of the parasympathetic nervous system?

Back

The parasympathetic nervous system promotes 'rest-and-digest' activities, conserving energy and facilitating bodily functions.

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 homeostasis?

Back

Homeostasis is the process by which the body maintains a stable internal environment despite external changes.

Front

What is the effect of the sympathetic nervous system on digestion?

Back

The sympathetic nervous system decreases digestive processes to redirect energy to more critical functions during stress.
