Question

Which of the following is a modified apocrine sweat gland
A) Sebaceous gland
B) Mammary gland
C) Mucous gland
D) Poison gland

Answer 1

Hint: Modified apocrine sweat glands are activated via hormonal stimulation during puberty in human beings. However, these apocrine glands are present more frequently in other mammals as well. Also, various modifications in apocrine glands have resulted in the development of certain specialized glands which are secretory in nature.

Complete answer:
The modified apocrine glands include the following mentioned glands:
Ceruminous glands are the glands which are present below the epithelial layer in humans. The sebaceous glands along with this gland make up ear wax.
Ciliary glands are also referred to as the glands of Moll. These glands are present at the margins of the eyelids. These provide lubrication to eyeballs by producing secretions.
Mammary glands are milk secreting glands.
On the other hand, Sebaceous glands are the holocrine glands while mucous gland is a type of merocrine gland and poison gland is a modified salivary or oral gland.

Therefore, the correct answer is option “B” that is Mammary gland is a modified apocrine sweat gland.

Note: Apocrine sweat glands secrete fatty sweat in its tubules. These glands are usually linked to hair follicles. The walls of tubules contract under emotional stress conditions. These drive out fatty secretions towards the skin, where they are broken down to fatty acids. These apocrine glands are generally present in the genital regions as well as armpit regions in the human beings. These glands are known to include mammary glands, various mammalian scent glands and glands that secrete ear wax.
