BIOL 3103 Test 2 review

What do all olfactory receptor cells have?

• cilia

• G-protein coupled receptors

• dissolved odorants that bind to a receptor and initiate an action potential.

• none of these

• all of these

Of the following, which does NOT help regulate the release of Ca2+?

• Calsequstrin

• Ryanodine

• Sarcolemma

• All of these help regulate Ca2+ release

Which sense does NOT proceed through the thalamus?

• Olfaction

• Gustatory

• Auditory

• Both A and B

True or False: Hair cells are only apart of the auditory system.

• True

• False

An increase in the delivery of oxygen (not binding) to tissue cells is increased by:

• higher (less acidic) pH

• increased CO2 production

• no oxygens being bound to hemoglobin

• non of the above

How does the pleural cavity affect the lungs?

• it helps the lungs remain elastic

• it prevents them from collapsing by using negative pressure

• It helps the lungs fill by using positive pressure

Which of the following is a function of the respiratory system?

True or False: The thalamus is involved in the processing of all sensory information.

• True

• False

If you only had parasympathetic control of cardiac output, you would no longer have control over:

• heart rate and stroke volume

• heart rate

• stroke volume

• you would still have control over both

If you increase the amount of extracellular K+ on the apical side of the auditory hair cells, what would the effect on hair cell function be?

• Decrease the likelihood of action potentials

• increase the likelihood of action potentials

• no effect

• it depends on where the hair cells are concentrated.
