1. Which of the following statements is false?
I. Outer cortex and inner medulla are the two zones in kidney
II. Medulla is divided into about 8 to 18 renal pyramids
III. Pyramid projects into calyx
IV. Inwards extension of cortex between the pyramids is called renal column of Bertini.
I and IV
II and IV
IV
None
Each kidney has how many nephrons?
About 2 millions
About 1 million
About 5000
About 50000
Renal corpuscle or Malpighian body is –
Glomerulus only
Glomerulus along with Bowman’s capsule
Bowman’s capsule
Glomerulus with afferent arteriole
Which one of the following is a tube that carries urine from kidney to the urinary bladder?
Loop of Henle
Ureter
Urethra
Uvula
The DCTs of many nephrons open into a straight tube called –
PCT
Loop of Henle
Collecting duct
Bowman’s capsule
Which of the following statements is false?
Renal tubule starts with a double walled cup like structure called Bowman’s capsule
In majority of nephrons, the loop of Henle is too short and such nephrons are cortical nephrons
Juxta medullary nephron has long loop of Henle
None
Vasa recta is –
L-shaped
S-shaped
U-shaped
J-shaped
In glomerulus, afferent arteriole –
Is wider than efferent arteriole
Is narrower than efferent arteriole
And efferent arteriole have similar diameter
Is narrow than efferent capillaries
Which of the following is incorrect?
Blood vessel leading to glomerulus is called efferent arteriole
Vasa recta, peritubular capillaries, Glomerulus all have blood
Cortical nephron has no or highly reduced vasa recta
Vasa recta runs parallel to the Henle’s loop in juxtamedullary nephrons
The layers between the blood in glomerular capillary and Bowman’s space are –
Tunica media + Cuboidal epithelium + Basement’s membrane
Endothelium + Epithelium of Bowman’s capsule + Basement membrane between the 2 layers
Endothelium of glomerular blood vessel + Endothelium of Bowman’s capsule + Parietal layer of Bowman’s
Cuboidal epithelium + Epithelium of Bowman’s capsule + Basement membrane between the 2 layers
