Summary Introduction

Introduction:

The mammary glands are the specialized, paired structures located on the chest. These organs have the main function to secrete milk to feed the young ones. These organs are also present in males but in females, they are more developed. Progesterone is the hormone that helps in the development of breasts. Prolactin helps form milk and is secreted from the anterior pituitary.

Answer to Problem 1DYKB

The correct answer is option (b) they are modified apocrine glands.

Explanation of Solution

Explanation/justification for the correct answer:

Option (b) is mammary glands are modified apocrine glands. These glands are found in both males and females but get activated only in females during pregnancy and lactation periods. Hence, this option is correct.

The explanation for the incorrect answers:

Option (a) is they release their secretion onto the hair follicle. Apocrine sweat glands secrete their secretions into the hair follicles. There are no hair follicles in mammary glands. Hence, this option is incorrect.

Option (c) is the product packaged in vesicles and released through exocytosis. In mammary glands, the secretion does not occur by exocytosis. Hence, this option is incorrect.

Option (d) is the product they secrete that acts as a lubricant and is waterproof. Ceruminous glands produce products that act as a lubricant and are waterproof. An example of such a product is ear wax. Hence, this option is incorrect.
