Question 1
Emphysema is characterized by overdistention and destruction of which of the following
structures?
Trachea
Bronchi
Bronchioles
Terminal bronchioles
Alveolar ducts
CORRECT ANSWER
alveolar ducts
Question 2
Intercellular passage of ions from the luminal surface of the intestines to the lamina
propria is prevented by the presence of ?
Desmosomes
Belt desmosomes
Hemidesmosomes
Gap junctions
Tight junctions/zonula occludens
CORRECT ANSWER
Tight junctions/ Zonula occludens
1
, Water is prevented from passing through the epithelial cells because of the zonula
occludens. They are sealants in between the surface of cells except in the sertoli cells.
Question 3
A diurnally secreted biogenic amine synthesized in pinealocytes is?
Dopamine
Epinephrine
Norepinephrine
Melatonin
Serotonin
CORRECT ANSWER
melatonin
Question 4
In the renal cortex, the labyrinth of the capillaries that carry resorbed glucose out of the
kidney arises directly from?
Afferent arterioles
Arcuate arteries
Capsular plexus
Efferent arterioles
Interlobular arteries
CORRECT ANSWER
efferent arterioles
2
, The proximal convoluted tubules carry reabsorbed glucose out of the kidney and the
glucose is reabsorbed in the vasa recta which is connected directly from efferent
arterioles
Question 5
Proliferation of uterine endometrium depends on?
Cortisol
Estrogen
Luteinizing hormone
Progesterone
Prolactin
CORRECT ANSWER
Estrogen
Menses, proliferative phase- estrogen, secretory phase- progesterone
Question 6
What stimulates the Secretory phase?
CORRECT ANSWER
Progesterone
Question 7
Which of the following cell types are found exclusively in the basal compartment of
seminiferous tubules?
3
, Primary spermatocytes
Secondary spermatocytes
spermatids
Spermatogonia
Spermatozoa
CORRECT ANSWER
Spermatogonia
Sertoli cells, tight junctions, spermatogonia- only cells found in the basal compartment
Everything else is in the adluminal compartment
Question 8
A suitable marker for determining that cells have differentiated into epidermal epithelial
tissue is expression of?
Desmin
Keratin
Vimentin
Histone H variant
CORRECT ANSWER
Keratin
Intermediate filaments associated with your epithelial cells is always keratin
Desmin and vimentin are always associated with your muscle tissues
