Anatomy and Physiology Test 2
A heavyset middle-aged insurance salesman who doesn't exercise often accepts his friend's
invitation to a pickup basketball game. When attempting a jump shot, he falls to the ground in pain,
grasping at the calf of his leg. There is an enormous bulge in his leg immediately below the knee, and
he is unable to plantar flex that foot. Most likely he has injured his ___ and the bulge is ___. -
correct answer Calcaneal Tendon
Triceps Surae
Which of the following best describes the resting membrane potential (RMP)? - correct answer The
intracellular environment is negatively charged
A clinician induces contraction of the gastrocnemius and soleus and notices that the foot does not
plantar flex as expected. Which of the following would be a logical diagnosis? - correct answer
Ruptured calcaneal tendon
The absence or inhibition of acetylcholinesterase at a synapse would lead to which of the following?
- correct answer Tetanus
To stimulate muscle contraction, acetylcholine is released from the ___________ into the synaptic
cleft. - correct answer Synaptic knob
Carpal tunnel pressure is sometimes relieved by surgically excising part or all of which structure? -
correct answer Flexor Retinaculum
Tennis elbow is a common term describing injury to which of the following? - correct answer
Extensor carpi radialus longus
In order for a peripheral nerve fiber to regenerate it must have - correct answer The soma and at
least some neurilemma intact
Which of the following would be caused by contraction of smooth muscle? - correct answer Goose
bumps
When the voltage of a plasma membrane shifts from +35mV towards 0 mV, we say the cell is -
correct answer Repolarizing
, Epidural anesthesia is introduced in the epidural space between the ___ to block pain signals during
pregnancy. - correct answer Dural sheath and vertebral bones
A male sustains a crushing injury to his foot. After weeks of care, he begins to notice that he cannot
bend the little toe on his right foot. A logical diagnosis would be - correct answer atrophy of the
flexor digiti minimi.
In lifting a heavy weight from the floor, one should use the power of the ___ in order to avoid
muscle strain in the lower back. - correct answer Knee and hip extensors
Which of these happens first in an adrenergic synaptic transmission? - correct answer G protein
dissociates from the NE receptor
Drugs called calcium channel blockers may be used to lower blood pressure by causing arteries to
vasodilate. These drugs - correct answer prevent calcium from entering smooth muscle, thus
allowing the muscle to relax.
In comparison to skeletal muscle, smooth muscle - correct answer Contracts are relaxes more
slowly
The most important mechanism for transmitting qualitative information is - correct answer The
labeled line code
If a bee sting on the right thigh causes a quick involuntary reaction of the right arm, this would be an
example of - correct answer An intersegmental reflex
Which of the following structures is the richest in lipid content? - correct answer White matter
A skeletal muscle generates the greatest tension when it is - correct answer Partially stretched
before being stimulated
An Olympic sprinter readies for a race. After the sound of the starting gun, he propels himself
forward from the starting block and immediately grimaces in pain, grabbing for the back of his thigh.
Within 48 hours he begins noticing extensive bruising on the back of his thigh extending into the
