Reproductive System Flashcards
Prostate shape, size and appearance (4)
- size of kiwifruit
- mass of 7-16g
- base (superior surface) and apex (inferior surface)
- smooth capsule surface
Prostate Location (3)
- male pelvic region
- midline and deep in pelvis
- close to pelvic floor
Prostate Zones (3)
- transitional (surrounds urethra)
- central (surrounds ejaculatrory ducts
- peripheral (wraps lateral and posterior surfaces)
Prostate relations (4)
- superior = urinary bladder
- inferior = urethra
- anterior = pubic symphysis
- posterior = rectum
Prostate blood supply + drainage (2)
- supply = inferior vesicle arteries
- drainage = visceral venous plexus to internal iliac veins
Prostate Lymphatics (3)
- obturator nodes
- external illiac nodes
- internal illiac nodes
Uterus Location (2)
- female pelvis (midline, true)
- expansion due to pregnancy into false pelvis and abdomen
Uterus shape, size and appearance (5)
- 7.5cm long, 5cm wide
- pear shaped
- rounded fundus (fallopian tubes attach)
- cervix inserts into vagina
- smooth surface
Uterus Ligaments (5)
- ligaments keep stable position without restricting
- broad ligament = attaches to pelvis bones
- uterosacral ligament = attaches to sacral bones
- cardinal ligaments = attach cervix to pelvic bones
- round ligaments = attach to vulva
Uterus Relations (4)
-Anterior = small intestine
- posterior = rectum
- inferior = urinary bladder
- lateral = pelvis bones
Uterus Blood supply and drainage (4)
- complex
- supply = uterine arteries + ovarian arteries
- drainage = venous return by ovarian veins
Uterus Lymphatic drainage (4)
- complex
- upper = paraaortic nodes
- lower = external iliac nodes
- can expand during pregnancy
Breast location (4)
- paired structures
- external structures attached to anterior chest wall
- 2nd to 6th ribs (sup/inf border)
- lateral edge of sternum to mid axilla axis (lat border)
Breast shape, size, appearance (5)
- hemispherical shape
- raised area = nipple
- areola = pigmented area around nipple
- vary greatly in size
- tissue extends obliquely into axilla (tail)
Breast Relations (3)
- posterior = anterior chest wall
- medial = sternum
- lateral = axilla
Breast Blood Supply and drainage (2)
- medial supply/drainage = internal thoracic
- lateral supply/drainage = axillary
Breast Lymphatic drainage (3)
- complex
- divided into lateral and medial drainage
- strong connection to axillary and upper limb drainage
Uterus 3 layers
- endometrium (mucosa of variable thickness due to cycle)
- myometrium (thick smooth muscular layer)
- perimetrium (visceral layer of peritoneum)
Perimetrium construction + function (3)
-functions as encasing capsule
- outer epithelial layer
- supported by connective tissue layer
Myometrium construction + function (4)
- functions to allow for stretching to accommodate fetus and contraction for delivery
- outer longituadally arranged muscle fibers
- middle circularly arranged muscle fibers
- deep longituadally arranged muscle fibers
Endometrium construction + function (3)
- functions to change in thickness as part of menstral cycle
- permanent layer of simple columnar epithelium (stratum basalis)
- changing layer of stratum functionalis
Uterus internal blood distribution (3)
- main supply is rich
- up to 3 orders of branching
- smallest vessels atrophy and regrow on a cyclical basis to build up thicker layer of endometrium
Breast construction (5)
- pockets of adipose tissue
- supported and compartmentalized by suspensory ligaments
- 15 - 20 lobes
- lobules contain clusters of alveoli
- ductal network from alveoli draining to nipple
