Zona reticularis, zona fasciculata, zona glomerulosa
-
Zona glomerulosa, zona reticularis, zona fasciculata
A
Correct answer
Explanation
Zona glomerulosa is the outermost layer of adrenal cortex. It is the major site for aldosterone synthesis and secretion, which is responsible for regulation of blood pressure. Zona fasciculata is the middle layer, which is responsible for secretion of glucocorticoids like cortisole, corticosterone, etc. The innermost layer is zona reticularis, which is responsible for secretion of androgens.

Wolfring glands
-
Zeis glands
A
Correct answer
Explanation
The meibomian glands or tarsal glands are a special kind of sebaceous gland at the rim of the eyelids inside the tarsal plate, responsible for the supply of meibum which is an oily substance that prevents evaporation of the eye's tear film.

Zeis glands
D
Correct answer
Explanation
Ciaccio glands or wolfring glands are small, tubular, accessory lacrimal glands found in the lacrimal caruncle of the eyelid. They are located in the upper border of the tarsus approximately in the middle between the extremities of the tarsal glands. Sometimes, they are situated slightly above the tarsus.

-
Testes
C
Correct answer

theria
-
utheria
-
metatheria
-
prototheria
D
Correct answer
Explanation
Prototherians (monotremes like platypus and echidna) have mammary glands that lack nipples. Milk is secreted onto specialized skin patches and the young lap it up. Theria includes all live-bearing mammals, Eutheria are placental mammals (with nipples), and Metatheria are marsupials (also have nipples). Option B has a typo ('utheria' should be 'eutheria').
