female anatomy Flashcards
What is the general function of the female repductive tract
Produce oocyte (gonad) - enable site of fertilisation (ampulla) - enable fetus nutriance + growth - enable birthing
What is the sections of the uterine tube + uterus
Uterine tube: lateral -> medial
-infundibulum (+fimbrea) -> ampulla (dilation, site fertilisation) -> isthmus
Uterus: Fundus + body
uterine wall:
perimetrium - outerconnective tissue
myometrium - smooth muscle, thickest layer, birthin
endometrium - grows + sheds
- stratum basal: stable inner layer
- straum functionalis: layer growns + shed during menstril cycle
What is the perinum divisions and the vulva
Perineum - urogenital triangle (vulva), anal triangle (anus)
Vulva:
mons pubis - pubic hair + adipose, at pubic symphisis
labia majora - latteral + larger
labia minora - medial + smaller
vestibule - space between labia minora
- vaginal opening
- urthra
- clitoris - glans, body, crura x2, + 2x bulbs
vestobule glands -
- major vestibule gland: stimulated with arrousal + lateral vaginal opening
- minor vestobule gland: adjacent to urethra secretion for lubrication
What is the sturcture of the cervix + the vagina
Cervix: central passage between uterus + vagina
- internal os -> cervical canal -> external os
- Secretes mucus regulate sperm movement: thickens when not wanted thins when wanted
- enters uterus at Fornix
Vagina: fibromuscular distendible copulation organ
- between rectum + urinary bladder
- run cervix to perineum
- contains rugae
What is the structure of the ovary
ovary = bilatteral structures posterior to uterus, held in place by ligaments
Medulla - enables blood supply, nerves, lyphatics
Cortex - location of oocytes + follicles: oocyte developes in the follicle
- oocyte relesed from ovary wall
- follicle -> corpus luteum, transient endocrine organ -> corpus albican (when no longer required)
What is the structure of the blood supply to the female reproductive system
Ovarian arteris - from aorta - travel with suspentory ligament
vaginal arteries - from internal iliac artery
uterine arteries - from internal iliac
- branching in myometrium -> arcuate arteries -> branch into endometrium -> radial arteries
- stratum basal - straight radial arteries
- stratum functionalis - spiral radial arteries
what is the structure of the the uterine ligament
ovarian ligament - between uterus and medial ovary
round ligament - between uterus -> through ingunal canal -> attaches to labia majora
suspentory ligament - attaches to the latteral ovary carrys blood vessles
board ligament - formed when 2 layers of peritoneum meets
mesovarian - around the ovarys
mesometrum - around the uterus
mesosalpinx - around the uterine tube
What are the pouches formed by the peritoneum
vesticouterine pouch - formed form the fold between uterus and urinary bladder
rectouterine pouch - formed from fold betwen rectum + uterus - posterior
what are the structures of the brests
Organ to provid infant with nourishment
Stimulated growth: 1st estradiol at puberty, 2nd progesterone at pregnacy
attached to pectoralis muscle by suspentory ligaments
Structures:
Lobe -> lobules -> alveolar -> lactiferous duct -> lactiferous sinus -> pore of nipple
