Exam IV part 2

Which of the following is not a result of parasympathetic stimulation?

A) dilation of pupils

What effect does the parasympathetic nervous system have on heart rate and blood pressure?

B) decreases heart rate and blood pressure

Sympathetic division stimulation causes ___________.

B) increased blood glucose, decreased GI peristalsis, and increased heart rate and blood pressure

Which is a uniquely sympathetic function?

B) regulation of body temperature

What do the parasympathetic and sympathetic nervous systems share in common?

C) Both systems are divisions of the autonomic nervous system.

Which of the following does not describe the ANS?

C) a system of motor neurons that innervates all muscle cells

Cardiovascular effects of the sympathetic division include all except:

C) dilation of the blood vessels serving the skin and digestive viscera

Preparing the body for the "fight-or-flight" response is the role of the ________.

C) sympathetic nervous system

The "resting and digesting" division of the autonomic nervous system is the ________.

As Lisa drive home she was suddenly alerted to the sound of a blaring horn and realized she had drifted off to sleep. Which nervous system division dominated when she was startled awake?

D) sympathetic nervous system

Compare and contrast the parasympathetic nervous system to the sympathetic nervous system. Include function name, nerves involved, alternate name for each, any exclusive innervations, and to antagonistic examples of effects.

The function name of the parasympathetic nervous system is rest and digest while the function name for the sympathetic nervous system is fight or flight. The alternate name for the PNS is the craniosacral nervous system and the alternate name for the SNS is the thoracolumbar nervous system. The nerves involved in the PNS are the oculomotor, facial, glossopharyngeal, vagus, and sacral nerves. The nerves involved in the SNS are the thoracic and lumbar nerves. Only sympathetic nerves are located in the skin, parasympathetic nerves will not be found in the skin. Two effects of the PNS are decreased heart rate and pupil constriction, while two effects of the SNS are increased heart rate and pupil dilation.
