Breast is composed of:

A. Glandular tissues only

B. Connective tissue only

C. Connective and fatty tissues

D. Glandular and fatty tissues

Correct Answer:D. Glandular and fatty tissues

Explanation

Breast is composed of the following structures:

Glandular tissue (Mammary glands)
- Contains 15–20 lobes arranged in a circular manner
- Each lobe has many smaller lobules that produce milk
Lactiferous ducts
- Tubes that carry milk from lobules to the nipple
Adipose (fat) tissue
- Fills spaces around lobes and ducts
- Determines the size and shape of the breast
Connective tissue (Fibrous tissue)
- Provides support and structure
- Includes Cooper’s ligaments that maintain shape
Nipple and Areola
- Nipple: Opening for lactiferous ducts
- Areola: Pigmented region around the nipple with sebaceous glands (Montgomery glands)
Blood vessels, lymph vessels, and nerves
- Rich blood supply
- Lymphatic drainage mainly to axillary lymph nodes

Breast = Glandular tissue + Ducts + Fat + Fibrous tissue + Nipple & Areola + Blood & lymph supply

Other Options Details

Here is the description of all the options:

This option refers to a structure composed entirely of glandular tissue, which contains secretory cells.
Glandular tissues are responsible for producing secretions such as milk (in mammary glands), hormones (in endocrine glands), or enzymes (in digestive glands).
If something is made only of glandular tissue, it means there is no support tissue like fat or connective tissue.

This structure consists entirely of connective tissue, which provides support, strength, and structure to organs.
Examples of connective tissue include ligaments, tendons, cartilage, and fibrous tissues.
If something is composed only of connective tissue, it means it has no glandular or fatty components.

This refers to a composition that includes both connective tissue (for support and structure) and fatty tissue (adipose tissue for storage and cushioning).
Fatty tissue also helps maintain shape and provide insulation.
Such a combination is commonly found in areas that require support and protection, such as the breast.

This structure contains a combination of glandular tissue (responsible for secretion) and fatty tissue (which gives shape and protection).
Example: the human breast is mainly composed of glandular and fatty tissues, along with small amounts of connective tissue.
Fat increases after puberty and pregnancy while glandular activity increases during lactation.
