Embryology, Anatomy and Breast histology

The development of the mammary glands begins in the embryonic stage with a thickening of the epidermis, forming the mammary ridge, which extends from the axillary to the inguinal region.

Embryology, Anatomy and Breast histology

Histology

2 Main tissues: Epithelial tissue and conjunctive tissue
It is made up of a fabric adipose and glandular

They are supported by ligaments called Cooper's ligaments

In infancy the secretory tissue is drained by middle a ductal system which stores the milk.

The lobes end through a tubular system in the galactophore ducts that discharge at the level of the nipple.

epithelial tissue lines the inside of the ducts galactophores

Embryology

Retromammillary region occurs intrauterinely
the first indication of the breast glands is a thickening of the epidermis

the mammary line at seven weeks of gestation extend to both sides of the body

Between 5th and 6th month their training begins

It occurs in both sexes

It goes from the axillary region to the inguinal region.

It is called the mammary ridge.

Form 8 aligned mammary foci sequentially, called milk line

The 4th focus will be the adult breast as it evolves the rest of the foci will atrophy

Towards the end of intrauterine life, the shoots epithelial cells canalize and form milk ducts

Anatomy

Located on the pectoralis major muscle and serratus anterior
Each mom is between 15 and 20 sections called lobes

are distributed like the petals of a daisy

Each lobe has many smaller lobules that end in tiny bulbs that produce milk.

The lobes, lobules and bulbs are joined by fine ducts called pipelines.

These ducts lead to the nipple

Fat fills in the gaps between the lobes and the ducts.

Each breast also contains vessels blood vessels and vessels that carry lymph

lymphatic vessels lead to organs small denominated lymph nodes

they are clusters that meet in many other parts of the body.

Located in the center of a dark area of skin called areola.
