Cervix
layers of the uterus (3)
Perimetrium

Perimetrium
bulk of uterus – three layers of muscle that contract under influence of oxytocin during labor.
Myometrium
highly vascular mucosa
Endometrium
shed during menstruation
Stratum functionalis
deeper, permanent layer, gives rise to new stratum functionalis
Stratum basalis
form from ectodermic tissue early in utero. they then remain in a halted stage of development until a rise in estrogen at puberty produces a marked increase in their size. the size increase occurs mainly because of an increase of connective tissue plus deposition of fat.
Breasts
has approximately 20 small openings through which milk is secreted
Nipple
is composed of smooth muscle that is capable of erection on manual or sucking stimulation. on stimulation, it transmits sensations to the posterior pituitary gland to release oxytocin.
Nipple
acts to constrict milk gland cells and push milk forward into the ducts that lead to the nipple.
Oxytocin
The skin surrounding the nipples is darkly pigmented out to approximately 4 cm
Areola
The area appears rough on the surface because it contains many sebaceous glands
Montgomery's tubercles
