A patient is given a drug that blocks the effects of ACh at the NMJ. This drug will…
cause impulse transmission from the nerve to the skeletal muscle cell.
True or False?
False
A patient is given a drug that blocks the effects of ACh at the NMJ. This drug will…
prevent calcium release from the SR
True or False?
True
A patient is given a drug that blocks the effects of ACh at the NMJ. This drug will…
cause skeletal muscle contraction
True or False?
False
The drug would inhibit muscle contraction by preventing ACh action at the NMJ, thus blocking signal transmission.
A patient is given a drug that blocks the effects of ACh at the NMJ. This drug will…
prevent myosin from binding to actin
True or False?
True
A patient is given a drug that blocks the effects of ACh at the NMJ. This drug will…
prevent ACh release from the nerve
True or False?
False
A patient is exposed to a toxin that blocks the action of ACh esterase ( a cholinesterase inhibitor). The toxin will…
prevent the breakdown of ACh
True or False?
True
A patient is exposed to a toxin that blocks the action of ACh esterase ( a cholinesterase inhibitor). The toxin will…
cause contracted muscle paralysis
True or False?
True
A patient is exposed to a toxin that blocks the action of ACh esterase ( a cholinesterase inhibitor). The toxin will…
prevent skeletal muscle relaxation
True or False?
True
A patient is exposed to a toxin that blocks the action of ACh esterase ( a cholinesterase inhibitor). The toxin will…
prevent skeletal muscle relaxation
True or False?
True
A patient is exposed to a toxin that blocks the action of ACh esterase ( a cholinesterase inhibitor). The toxin will…
increase the amount of ACh at the NMJ
True or False?
True
A patient is given a drug that blocks PTH activity. This drug…
causes osteoclast activity to increase
True or False?
False
A patient is given a drug that blocks PTH activity. This drug…
causes osteoblast activity to decrease
True or False?
False
A patient is given a drug that blocks PTH activity. This drug…
decreases blood calcium
True or False?
True
A patient is given a drug that blocks PTH activity. This drug…
decreases bone breakdown
True or False?
True
A patient is given a drug that blocks PTH activity. This drug…
would be beneficial if blood calcium levels were too high
True or False?
True
The distal part of the thigh is closer to the hip than to the knee.
True or False?
False
The proximal part of the arm is closer to the elbow than to the shoulder
True or False?
False
The heart is medial to the lungs
True or False?
True
The abdomen is inferior to the thorax.
True or False?
True
The 3rd finger is lateral to the 4th finger.
True or False?
True
The 2nd toe is medial to the 4th toe.
True or False?
True
Diffusion requires a concentration gradient.
True or False?
True
Synaptic vesicles are on the presynaptic side of the NMJ.
True or False?
True
Bone is a type of connective tissue
True or False?
True
Muscle tissue is one of four basic tissue types.
True or False?
True
The epidermis is the most superficial layer of the skin.
True or False?
True
Osteoblasts build bone
True or False?
True
Osteoclasts tear down bone
True or False?
True
A decrease in blood calcium causes PTH secretion to decrease in response.
True or False?
False
An increase in calcitonin secretion causes blood calcium to increase.
True or False?
False
Abnormally low PTH secretion would decrease bone density.
True or False?
False
The pleura surrounds the lungs.
True or False?
True
The pericardium surrounds the heart.
True or False?
True
