Solution(By Examveda Team)

Mammary glands originate from Ectoderm.
A mammary gland is an exocrine gland in humans and other mammals that produces milk to feed young offspring. It is directed by hormonal guidance from sex steroids.
The basic components of a mature mammary gland are the alveoli (hollow cavities, a few millimeters large), which are lined with milk-secreting cuboidal cells and surrounded by myoepithelial cells.
