Functionally, the mammary glands produce milk; structurally, they are modified sweat glands. Mammary glands, which are located in the breast overlying the pectoralis major muscles, are present in both sexes, but usually are functional only in the female.

What type of gland is the mammary gland?
It is also a vital accessory organ of the female reproductive system. Type: It is an apocrine type of gland. In these glands, the apical part of the cells and a part of the cytoplasm are lost in the secretion. Situation: The mammary gland is situated in the pectoral region in the superficial fascia.
What are modified mammary glands?
The mammary glands, or breasts, are actually modified sebaceous glands (sweat) that are designed to secrete milk. On average, each breast weighs 200–300 g. They are composed of glandular tissue, fat, and supporting or stromal tissue. Each breast is organized into 12–25 triangular shaped lobes.
Are mammary glands modified Holocrine glands?
Mammary glands, which secrete milk, are apocrine type. ... Sebum secreting sebaceous glands on facial skin are holocrine type. Secretory cell with its product gets dislodged from basal membrane and cells are regularly lost inside the gland producing sebum.
Is mammary an endocrine gland?
These cases illustrate that the mammary gland is not just a gland which delivers milk in response to certain stimuli, but that it also transmits humoral signals, i.e., the mammary gland is an endocrine gland.
Why mammary gland is modified sweat gland?
Functionally, the mammary glands produce milk; structurally, they are modified sweat glands. ... Each lobe consists of lobules that contain the glandular units. A lactiferous duct collects the milk from the lobules within each lobe and carries it to the nipple.
Why breast is called modified sweat gland?
Mammary glands or breasts are actually sweat glands that have been modified according to hormonal stimulation. ... The presence of the female hormone estrogen is responsible for the growth and development of the female breasts. In most males, the glandular tissue within the breast remains rudimentary.
Are mammary glands endocrine or exocrine?
Exocrine Glands
These glands include the sweat, sebaceous, and mammary glands and, the glands that secrete digestive enzymes.
Do amphibians have mammary glands?
Within the animal kingdom, there are many classes of animals that do not have mammary glands such as insecta or insects, amphibia or amphibians, mollusca or molluscs, crustacea or crustaceans, and chelicerata or chelicerates. ... Amphibians include frogs and salamanders; molluscs include snails, clams and squid.
Are salivary glands holocrine?
Merocrine glands, such as salivary glands, pancreatic glands, and eccrine sweat glands, are comprised of secretory cells that excrete products through exocytosis (into the epithelial-walled ducts and then to lumen) without causing any damage or loss in the secretory cell. ... holocrine gland.
What is an example of holocrine glands?
Examples of holocrine glands include the sebaceous glands of the skin and the meibomian glands of the eyelid. The sebaceous gland is an example of a holocrine gland because its product of secretion (sebum) is released with remnants of dead cells.
Are sebaceous glands holocrine?
Sebaceous glands are holocrine glands that open through a sebaceous duct into the infundibulum of primary hair follicles. Sebaceous glands secrete an oily emulsion called sebum.
Which type of epithelium is found in parts of mammary glands?
The mammary gland is like a modified sweat gland. Each of theses lobes is a compound tubular acinar gland. The acini empty into ducts, that are lined by cuboidal, or low columnar epithelial cells, and surrounded by myoepithelial cells.
Are salivary glands endocrine or exocrine?
comparison with endocrine gland
Salivary glands and sweat glands are examples of exocrine glands. Both saliva, secreted by the salivary glands, and sweat, secreted by the sweat glands, act on…
Is the mammary gland part of the reproductive system?
The female reproductive system includes the ovaries, fallopian tubes, uterus, vagina, vulva, mammary glands and breasts. These organs are involved in the production and transportation of gametes and the production of sex hormones.
