Ch. 14 Module 4: Sections 14.07-14.09 Dynamic Study Module

Which of the following is correctly matched for heart muscle?

Parasympathetic decreases heart rate and sympathetic increases rate and force of the heartbeat

For the levels of ANS control, match the following: "E."

Reflexes for urinat ion, defecation, erection, and ejaculation

For the levels of ANS control, match the following: "D."

Regulates pupil size, heart, blood pressure, airflow, salivation, etc.

For which of the following targets is the sympathetic division the major actor, even at rest?

Smooth muscle of blood vessels

For the levels of ANS control, match the following: "C."

The boss: Allows for overall integration of the ANS

The parasympathetic nervous system innervates which of the following targets?

Iris

Which of the following is true?

Most autonomic disorders reflect exaggerated or deficient controls of smooth muscle activity.

Which letter represents an area where biofeedback studies have shown that voluntary cortical control of visceral activities is possible? While this capability is untapped in most people, this would allow for self control over heart rate and blood pressure.

A

Select the effector that does not receive innervation from the parasympathetic division.

Adrenal medulla

With respect to the sympathetic and parasympathetic divisions, which of the following is matched correctly?

All of the listed responses are matched correctly.

Which letter represents the specific system that causes the skin to turn red after taking a very warm shower or sitting in a Jacuzzi?

C

Which letter represents the system that causes ejaculation of semen by the penis or reflex contractions of the vagina?

C

Which letter represents the system that innervates adipose tissue to stimulate fat breakdown?

C

Which letter represents the system that is responsible for widespread and prolonged effects that require time to "come down" from?

C

Which letter represents the system that most specifically regulates blood vessel diameter?

C

Which letter represents the system that most specifically regulates the release of renin from the kidney?

C

Which letter(s) represents the system that (1) increases the metabolic rate of body cells; (2) raises blood glucose levels; and (3) mobilizes fats for use as fuels.

C

For the levels of ANS control, match the following: "A."

Cerebral cortex modifies ANS activity by acting through limbic system structures

Which letter represents the system that stimulates erection of the male penis or female clitoris during sexual excitement?

D

For the levels of ANS control, match the following: "B."

Emotional responses of the limbic system to danger and stress signal the hypothalamus to activate the sympathetic system to fight-or-flight status

In some cases of trauma to the spinal cord, the normally cooperative innervation of the reproductive organs will be interrupted by disruption of the sympathetic nervous system. Unopposed parasympathetic activity in the reproductive system would result in what sign in males?

Erection of the penis

Match the following homeostatic imbalance of the ANS with its cause: Raynaud's disease.

Exaggerated vasoconstriction response to cold or emotional stress (occurs in fingers and toes)

Match the following parasympathetic action with its target organ: Stimulates muscles.

Eye

Match the following parasympathetic action with its target organ: Excites.

Gallbladder

Which of the following is true with regards to localized versus diffuse effects of the autonomic nervous system?

Hormones released by the adrenal medullary cells into the blood require destruction by the liver and thus are relatively long lasting.

Which of the following effects of the sympathetic and parasympathetic divisions is true?

In blood coagulation, the parasympathetic nervous system has no effect (no innervation) and the sympathetic nervous system increases coagulation. OR In the lungs, the parasympathetic nervous system constricts bronchioles and the sympathetic nervous system dilates bronchioles. OR In the kidney, the parasympathetic nervous system has no effect (no innervation) and the sympathetic nervous system promotes renin release; causes vasoconstriction; decreases urine output.

Which of the following examples of dual innervation is incorrect?

In the liver, the parasympathetic nervous system increases glucose uptake from blood and the sympathetic nervous system stimulates release of glucose to blood.
