Question

Describe human mammary glands.

Answer 1

Mammary glands: 

• In Prototheria, human beings and other primates, the mammary glands are modified apocrine sweat glands. In remaining mammals, they are modified compound alveolar sebaceous glands. 
• Each mammary gland has a teat through which the mammary gland opens out. The area around the teat is darkly pigmented which is called as areola mammary. 
• The mammary glands secrete the milk. The milk contains mainly carcinogen, lactoglobulin, lactoalbumin, lactose and fats. In human beings, there is a pair of mammary glands on the thorax.
