Lecture Quiz Questions (for final exam)

Question 1

T/F: The sympathetic division of the viscerosensory system conveys innocuous information from the viscera.

Answer 1

False

• The sympathetic division conveys pain information
• The parasympathetic division conveys innocuous sensory information`

Question 2

T/F: Visceral pain is poorly localized and often referred to along a dermatome of the somatic nervous system secondary to “cross talk” between the visceral and somatic sensory systems

Answer 2

True

Question 3

T/F: The blood vessels of the skin and skeletal muscles of the body wall and limbs are innervated by only the sympathetic division of the ANS.

Answer 3

True

Question 4

Which of the following statements correctly describes the structural components of the parasympathetic division of the ANS? Select all that apply.

A. Pre-ganglionic neurons are located in cranial visceromotor nuclei & at sacral levels of the spinal cord.
B. Pre-ganglionic neurons are located in the intermediolateral cell column at the levels of T1-L2.
C. Post-ganglionic neurons are located in ganglia in the head region and intramural ganglia.
D. Post-ganglionic neurons are located in the sympathetic chain of ganglia.
E. Acetylcholine is the neurotransmitter that allows communication between the pre and post-ganglionic neurons, as well as between the post-ganglionic neurons and the target tissue.

Answer 4

A, C, E

Question 5

Your patient sustained a neck injury that damaged the right superior cervical ganglion. You anticipate seeing which of the following clinical signs. Select all that apply.

A. left facial flushing
B. right facial flushing
C. right ptosis
D. right pupil constriction
E. left anhidrosis

Answer 5

B, C, D

• deficits of the cervical ganglion are seen ipsilateral to the injury

Question 6

T/F: In order to empty the bladder there needs to be contraction of the smooth muscle of the bladder wall (detrusor muscle), relaxation of the internal urethral sphincter, and contraction of the external urethral sphincter.

Answer 6

False

The external sphincter must RELAX not CONTRACT.

Question 7

Which of the following statements best describes the micturition reflex?

A. Decreased firing rate of the sensory afferents of the bladder wall results in increased parasympathetic outflow, increased sympathetic outflow, and inhibition of the somatic motor neurons resulting in bladder voiding.
B. Increased firing rate of the sensory afferents of the bladder wall results in increased parasympathetic outflow, decreased sympathetic outflow, and inhibiton of the somatic motor neurons resulting in bladder voiding.
check
C. Increased firing rate of the sensory afferents of the bladder wall results in decreased parasympathetic outflow, increased sympathetic outflow and inhibition of the somatic motor neurons resulting in bladder voiding.
D. Decreased firing rate of the sensory afferents of the bladder wall results in decreased parasympathetic outflow, decreased sympathetic outflow and excitation of the somatic motor neurons resulting in bladder voiding.

Answer 7

???

Question 8

T/F: Baroreceptors are located in the carotid sinus and the aortic arch and increased tension in the walls of these arteries causes a reduction in the firing rate of these receptors.

Answer 8

False

• Vessels will increase not decrease their firing rate

Question 9

Which of the following statements correctly describes what will happen during an acute episode of hypertension?

A. Baroreceptors will decrease their firing rate resulting in an increase in parasympathetic outflow and a decrease in sympathetic outflow producing the vasodepressor response.
B. Baroreceptors will increase their firing rate resulting in an increase in parasympathetic outflow and a decrease in sympathetic outflow producing the vasodepressor response.
check
C. Baroreceptors will decrease their firing rate resulting in an decrease in parasympathetic outflow and an increase in sympathetic outflow producing the vasopressor response.
D. Baroreceptors will increase their firing rate resulting in an decrease in parasympathetic outflow and a increase in sympathetic outflow producing the vasopressor response.

Answer 9

B. Baroreceptors will increase their firing rate resulting in an increase in parasympathetic outflow and a decrease in sympathetic outflow producing the vasodepressor response.
