A&P 2 FINAL Questions with Verified
Answers
True or False: if false, explain why the statement is false:
Sensory neurons send messages from the central nervous system to the peripheral -
ANSWERSFalse; motor neurons send messages from the central nervous system to
the peripheral
Match the following phases of an action potential with correct description
Resting potential; Depolarization; Repolarization; Afterpolarization
A. Sodium and potassium gates are closed
B. Potassium rushes out of the neuron
C. Undershoot of the potential
D. Sodium rushes into the neuron - ANSWERSResting potential - A. sodium and
potassium gates are closed
Depolarization - D. Sodium rushes into the neuron
Repolarization - B. Potassium rushes out of the neuron
Afterpolarization - C. Undershoot of the potential
True or False: If false, explain why the statement is false -
The peripheral nervous system consists of the brain and spinal cord - ANSWERSFalse,
the central nervous system consists of the brain and spinal cord
Match each of the following brain regions with the correct description
Hippocampus; Thalamus; Hypothalamus; Amygdala; Basal ganglia
A. Involved in emotions such as rage and anger
B. Regulates planning motor movements and motor learning
C. Involved in retrieval and storage of memories
D. Central relay station for sensory impulses
E. Maintains homeostasis - ANSWERSHippocampus - C. Involved in retrieval and
storage of memories
Thalamus - D. Central relay station for sensory impulses
Hypothalamus - E. Maintains homeostasis
Amygdala - A. Involved in emotions such as rage and anger
Basal ganglia - B. Regulates planning motor movements and motor learning
Fill in the blank:
The __ root contains the axons of sensory neurons, while the __ root contains the
axons of motor neurons - ANSWERSDorsal; Ventral
, Explain how the sympathetic and parasympathetic nervous system have opposite
effects on visceral organs - ANSWERSThe sympathetic system accelerates the
heartbeat, dilates the bronchi, and increases the breathing rate. Sympathetic activates
the digestive tract since digestion is not an immediate necessity when in danger.
Parasympathetic stimulation causes the pupil of the eye to constrict and helps the
lenses of the eye to focus on nearby objects; it promotes digestion of food. The
parasympathetic acts to slow heart rate.
Which the following is NOT one of the eye muscles responsible for eye movements?
A. Anterior rectus
B. Superior oblique
C. Inferior rectus
D. Lateral rectus - ANSWERSA. Anterior rectus
A patient comes to the doctors office complaining of some hearing loss. The doctor
finds the patient has significant cerumen buildup. Would this be an example of
conduction deafness or nerve deafness? - ANSWERSThe patient is suffering from
conduction deafness. It occurs from the damage to the outer and middle ear structures,
the buildup can partially block sound waves entering the external acoustic meatus.
Which cells serve as stem cells in the gustatory system that divide and differentiate into
new supporting cells that then form gustatory cells? - ANSWERSBasal cells
Fill in the blank:
The ___ valve controls the flow of blood form the right atrium into the right ventricle. The
___ valve controls the flow of blood from the left atrium into the left ventricle. -
ANSWERSTricuspid; Mitral
Which vessels contain the largest amount of blood in the cardiovascular system? -
ANSWERSVeins have compliance, stretch with little recoil. Therefore, veins have the
largest amount of blood.
Which of the following is NOT a type of Granulocyte?
A. Eosinophils
B. Basophils
C. Neutrophils
D. B-Cells - ANSWERSD. B-cells
Why is the SA node known as the pacemaker of the heart? - ANSWERSIt begins the
electrical impulses necessary for cardiac cycle
Which of the following cardiovascular conditions is sometimes called a "silent killer"?
A. Hypertension
B. Edema
