The Mammary Glands

2.2K
The female breast is a hemispheric projection of variable size positioned anterior to the pectoralis major and serratus anterior muscles. A fascia layer composed of dense, irregular connective tissue connects it to these muscles.
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...

Tissues

Cells with similar structure and function are grouped into tissues. A group of tissues with a specialized function is called an organ. There are four main types of tissue in vertebrates: epithelial, connective, muscle, and nervous.

Tissues

68.4K
Tissues are a group of cells that share a common embryonic origin. Microscopic observation reveals that the cells in a tissue share morphological features and are arranged in an orderly pattern to perform specific functions. From an evolutionary perspective, tissues appear in more complex organisms. Although there are many types of cells in the human body, they are organized into four broad categories of tissues: epithelial, connective, muscle, and nervous. Each of these categories is...

Plant Cells and Tissues

65.8K
Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be combined with other tissues to form organs such as flowers, fruit, stem, and leaves. Two major types of plant tissue include meristematic and permanent tissue.

Plant Tissue Culture

40.7K
Plant tissue culture is widely used in both primary and applied science. Applications range from plant development studies to functional gene studies, crop improvement, commercial micropropagation, virus elimination, and conservation of rare species.

Tissue Membranes01:27

Tissue Membranes

8.4K
A tissue membrane is a thin layer of cells that covers the outside of the body, the organs, internal passageways that lead to the exterior of the body, and the lining of the moveable joint cavities. There are two basic types of tissue membranes— connective tissue and epithelial membranes.
Connective Tissue Membranes
The connective tissue membrane is formed solely from connective tissue. These membranes encapsulate organs, such as the kidneys, and line our movable joints. A synovial...

Summary

Ectopic breast tissue, found along the embryonic milk ridge, can present as a complete accessory breast, aberrant breast tissue, or polythelia. While rare, this tissue can develop tumors like fibroadenoma or carcinoma.

Area of Science:

  • Embryology
  • Human Anatomy
  • Pathology

Background:

  • Ectopic breast tissue is a congenital anomaly.
  • It can manifest in various forms, including accessory breast, aberrant breast tissue, and polythelia.
  • Its typical location is along the embryonic milk ridge.

Purpose of the Study:

  • To describe the anatomical locations and variations of ectopic breast tissue.
  • To highlight the potential for neoplastic development within ectopic breast tissue.

Main Methods:

  • Review of anatomical and pathological literature.
  • Analysis of case reports and clinical observations.

Main Results:

  • Ectopic breast tissue follows the embryonic milk ridge from axilla to vulva.
  • Common sites include the axilla, breast, and surrounding areas.
  • Tumors such as fibroadenoma and carcinoma can arise from ectopic breast tissue.

Conclusions:

  • Ectopic breast tissue is a recognized anatomical variation.
  • Understanding its distribution and potential for pathology is crucial for clinical diagnosis and management.
