Example Question #151 : Muscles
Which make up the wrist and the body of the hand?
tarsals and phalanges
carpals and metacarpals
carpals and phalanges
tarsals and metatarsals
carpals and metacarpals
The carpals and metacarpals make up the wrist and the body of the hand, respectively. The tarsals and metatarsals make up the ankle and the body of the foot, respectively. The phalanges are the bones of the fingers and toes.
Example Question #151 : Muscles
If the efferent arteriole becomes constricted, what is likely to occur in the nephron?
Glomerular filtration rate will decrease due to a loss in blood pressure
The increased osmotic pressure will elevate glomerular filtration rate
Glomerular filtration rate will remain the same
Fluid backup will cause the nephron to rupture
The increased hydrostatic pressure will elevate glomerular filtration rate
The increased hydrostatic pressure will elevate glomerular filtration rate
The efferent arteriole carries blood away from the glomerulus, and so if it is constricted, the blood pressure behind it will increase. The raise in blood pressure will result in an increase in hydrostatic pressure, pushing additional fluid through the glomerulus i.e elevated glomerular filtration rate. While high hydrostatic pressure does cause damage to the nephron, the nephron rupturing is too extreme of a statement and requires assumptions that are not necessarily valid.
