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
Summary
Breast = Glandular tissue + Ducts + Fat + Fibrous tissue + Nipple & Areola + Blood & lymph supply
Other Options Details
Here is the description of all the options:
A. Glandular tissues only
- 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.
B. Connective tissue only
- 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.
C. Connective and fatty tissues
- 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.
D. Glandular and fatty tissues
- 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.
