Question	Answer
Which is true of a neuron with a resting potential?	The sodium pump has moved Na+ to the outside of the plasma membrane.
Which neuron could transmit a nerve impulse the fastest?	A large-diameter neuron with myelin
Stimulus-gated channels open in response to	Sensory stimuli
Severe depression can be caused by a deficit in certain brain synapses of:	Amines
A synaptic knob would be located on a(n):	axon
The neurotransmitter(s) that inhibit(s) the conduction of pain impulses is(are):	enkephalins
When current leaps across an insulating myelin sheath from node to node, the type of impulse conduction is called:	saltatory conduction.
Excitatory neurotransmitters are most likely to:	initiate an action potential.
Movement of the membrane potential away from zero (below the usual RMP) is called	hyperpolarization
The part of the brain that can directly influence or inhibit the release of hormones from the pituitary is the:	hypothalamus.
Acetylcholine can stimulate _____ receptors.	nicotinic
How does a dually innervated autonomic effector differ from a singly innervated autonomic effector?	A dually innervated effector receives input from both sympathetic and parasympathetic pathways. A singly innervated autonomic effector receives input from only the sympathetic division.
T/F: The parasympathetic and sympathetic divisions always act with a cooperative influence, and through summation of the impulses, the effect can be increased.	false
Damage to the _____ nerve could make the diaphragm unable to function.	phrenic
Nerve impulses over the _____ nerve cause increased peristalsis and decreased heart rate.	vagus
Which of the following is a description of the principle of autonomic antagonism as it relates to the autonomic nervous system?	If sympathetic impulses tend to stimulate an effector, parasympathetic impulses tend to inhibit it.
In comparison with the nervous system, the regulatory effects of the endocrine system are:	slow to appear but long-lasting.
The receptors responsible for sensing crude and persistent touch are the:	Ruffini corpuscles.
When a small amount of one hormone allows a second hormone to have its full effect, the phenomenon is called:	permissiveness.
Dynamic equilibrium depends on the functioning of the	crista ampullaris.
The sequence of auditory ossicles in the middle ear starting at the tympanic membrane and ending at the oval window is: Correct!	malleus, incus, and stapes.
Movement of hair cells in the organ of Corti against the _____ membrane can stimulate nerve impulse condition.	tectorial
The clear and potassium-rich fluid that fills the labyrinth is	endolymph.
Which of the following statements is not true of the pineal gland?	Melatonin is stimulated by the presence of sunlight.
The mechanisms of which three hormones work together to regulate blood volume?	aldosterone, ANH, and ADH
_____ is used to determine the volume percentage of red blood cells in whole blood.	Hematocrit
A hematocrit of 56% would be an indication of:	polycythemia.
Which are the two baroreceptors that are located near the heart?	aortic baroreceptors and carotid baroreceptors
If damaged, which valve could allow blood to leak back into the right atrium?	Tricuspid
Inhibition of sympathetic vasoconstrictor impulses is considered a major mechanism of	vasodilation.
The chemoreceptors in the carotid bodies are particularly sensitive to:	hypercapnia.
Recognition of antigens by antibodies occurs when an	antigen’s epitopes fit into and bind to an antigen molecule’s antigen-binding site.
The ingestion and destruction of microorganisms or other small particles is called	phagocytosis.
The function of which antibody is basically unknown?	IgD
Molecules formed by the reactions of the complement cascade assemble themselves on the enemy cell’s surface, which results in	cytolysis.
Chemotaxis is the process by which a cell navigates toward the source of the chemotactic factor by way of	detecting and then moving toward higher concentrations of the factor.
Pyrogen molecules trigger the fever response by promoting the production of	prostaglandins.
The movement of phagocytes from blood vessels to an inflammation site is called	diapedesis.
The lymphatic system serves various functions in the body. The two most important functions of this system are	fluid balance and immunity.
The vital capacity is equal to the sum of the:	inspiratory reserve volume, tidal volume, and expiratory reserve volume.
Which of the following would you expect to happen to cellular respiration during exercise?	Increased cellular respiration occurs during exercise, causing a rise in plasma PCO2, which is detected by central chemoreceptors in the brain and perhaps peripheral chemoreceptors in the carotid sinus and aorta to cause an increase in respiration rate.
The term used to describe the volume of air exchanged during normal inspiration and expiration is:	Tidal volume
The PCO2 in the atmosphere is:	less than in the alveolar air.
Standard atmospheric pressure is _____ mm Hg.	760
Which of the following constitutes total lung volume?	Residual volume and vital capacity
Which of the following combinations in arterial blood could cause an increase in the respiratory rate?	Increased PCO2, decreased arterial pressure, decreased pH, decreased PO2
Which of the following is not a regulated process associated with the functioning of the respiratory system?	Control of cell metabolism rate
Which gas law deals with the solubility of gases in solution?	Henry
The function of the vibrissae in the vestibule is to:	provide an initial “filter” to screen particulate matter from air that is entering the system.
The enterogastric reflex causes:	inhibition of gastric peristalsis.
The hormone thought to be a messenger causing release of digestive enzymes from the intestinal mucosa is:	vasoactive intestinal peptide.
Which of the following is a disaccharide?	Sucrose
The sodium cotransport or coupled transport acts to transport sodium ions and glucose molecules _____ the GI lumen.	passively out of
The hormone that stimulates the release of bicarbonate substance from the pancreas is:	secretin
Hydrolysis refers to:	using water to split larger compounds into smaller ones.
The substances absorbed into the lymph capillaries are:	glycerol and fatty acids.
Which phase(s) of gastric secretion is(are) stimulated by the sight, taste, and smell of food?	Cephalic phase
Which blood vessel carries absorbed food from the GI tract to the liver?	portal vein
Polysaccharides are hydrolyzed into disaccharides by enzymes known as:	amylase
