Anatomy of the Nervous System

Front

What is the primary function of the Vagus nerve (CN X)?

Back

The Vagus nerve (CN X) is primarily responsible for parasympathetic control of the heart, lungs, and digestive tract.

Front

What is a parasympathetic effect on heart rate?

Back

A parasympathetic effect decreases heart rate.

Front

What is the role of the parasympathetic division of the ANS?

Back

The parasympathetic division promotes 'rest and digest' functions, enhancing digestive activity and conserving energy.

Front

What organ is primarily affected by damage to the celiac ganglion?

Back

The stomach is primarily affected by damage to the celiac ganglion.

Front

What neurotransmitter is associated with sympathetic responses such as increased heart rate and sweating?

Back

Norepinephrine is the neurotransmitter associated with sympathetic responses.

Front

What are the main divisions of the Autonomic Nervous System (ANS)?

Back

The main divisions of the ANS are the sympathetic and parasympathetic divisions.

Front

What is the effect of the sympathetic division on the respiratory system?

Back

The sympathetic division causes bronchodilation, increasing airflow to the lungs.

Front

What is the primary function of the sympathetic division of the ANS?

Back

The sympathetic division prepares the body for 'fight or flight' responses, increasing heart rate and energy mobilization.

Front

What is the effect of parasympathetic stimulation on digestive activity?

Back

Parasympathetic stimulation increases digestive activity.

Front

What is the role of acetylcholine in the autonomic nervous system?

Back

Acetylcholine is the primary neurotransmitter used by the parasympathetic division.
