Embryology, Anatomy and Breast histology

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

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

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.

Embryology

Retromammillary region occurs intrauterinely

the first indication of the breast glands is
a thickening of the epidermis

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

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

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.
