The ANS stimulates smooth muscles, skeletal muscles and glands, whereas the somatic nervous system innervates skeletal muscles only.

A patient with diabetes comes into the doctor's office complaining of sexual dysfunction, dizziness upon standing, and sluggish eye pupil reactions. What is causing the patient's issues and how should it be treated?

Baroreceptors in the carotid sinus monitor blood pressure.

How would external stimulation of the carotid artery, such as carotid massage, affect the heart rate?

In what ways are the autonomic and the somatic nervous systems different?

The parasympathetic fibers of the _________ nerve stimulate many large glands in the head such as the nasal and lacrimal glands.

Discuss a way in which the sympathetic and parasympathetic divisions cooperate with each other.

Which of the following drug classes would be useful for smoking cessation products?

Which target organ receives dual innervation?

Which of the following appears to exert the most direct influence over autonomic functions?

The rami communicantes are associated only with the sympathetic division of the ANS.

Most blood vessels are innervated by the sympathetic division alone.
