Ligaments: all ligaments are primarily dense regular CT in structure Ovarian ligament Cord like portion of broad ligament Attaches upper portion of uterus to medial/inferior surface of ovary Broad ligament: Fold of the peritoneum Encloses & anchors ovaries, uterine tubes, and uterus to sides & floor of pelvic cavity Suspensory ligament Small fold of peritoneum Attaches lateral/superior surface of ovary to pelvic wall Contains ovarian artery & vein
Slide 6-

Know the ligament locations on a diagram
Slide 7-

Ovaries: female gonads Paired glands Size & shape of almonds Function: Produce ova through process of oogenesis Produce & secrete female hormones
Slide 8-

Ovaries: female gonads Tunica albuginea Dense CT layer on surface of ovary Provides structure & support Stroma Interior tissues of ovary composed of cortex & medulla Functional tissue of ovary Cortex Superficial layer Contains ovarian follicles Medulla Deep layer Contains larger BV, LV, & NF

Uterine tubes (Fallopian tubes, oviducts) Fallopian tubes Paired tubular structures Function: Passageway for sperm to reach egg Site of fertilization Passageway for fertilized egg to reach uterus

Slide 12-

Parts of Fallopian tube Infundibulum: funnel shaped portion located closest to ovary Funnels/receives egg into Fallopian tube Fimbria: finger like projections at end of infundibulum No physical connection to uterus Function: lined with cilia: movement creates current to draw egg into infundibulum
Slide 13-

Uterus Structure: 3” x 2” and approx. 1.75-3.5 oz Hollow, muscular pear shaped Function: receives fertilized embryo protect, nourish & remove wastes for the developing child
Slide 14-

Uterine structures Fundus: dome shaped top portion Entry point of uterine tubes Body: upper 2/3 of uterus Contains uterine cavity Hollow interior of body – contain developing child Cervix: Lower 1/3 of uterus – tubular “neck” Muscular opening into vagina Closes to hold baby in uterus

Uterine wall - layers Perimetrium: outer serosa (serous membrane) – simple squamous & areolar CT Reduce friction from surrounding organs Myometrium: middle layer – 3 layers of smooth muscle Contract during childbirth to push child out of body Contract slightly to shed functional layer of endometrium during menses
Slide 17-

Uterine wall - layers Endometrium: Highly vascularized inner layer Two layers: functional layer : discharged during menses basal layer: permanent layer

Vaginal structure Vagina: fibromuscular tube 3-3.5 inches long Highly distensible (stretchy) Functions: Conveys uterine secretions, such as menstrual fluids. Receives erect penis Open channel for birth
Slide 21-

Vaginal structure Fornix: shallow recess (pockets) between vaginal wall & cervix protrusion Allows for expansion of cervix & vaginal canal during birth Allow physician to palpate AP organs/provide surgical access Hymen: elastic epithelial membrane fold Partially blocks opening to vagina

External Genitalia
Slide 24-

Vulva – aka Pudendum Structures surrounding the openings of the urethra and vaginal canal
Slide 25-

Structures of the vulva Labia minora: longitudinal folds of CT Encloses vestibule Protects openings to vagina and urethra Labia majora: homologous to scrotum: skin, adipose, smooth muscle Encloses and protects labia minora & other vulvar structures
Slide 26-

Structures of the vulva Mons pubis: rounded elevation of adipose tissue over pubic symphysis Protective structure
Slide 27-

Structures of the vulva Clitoris: homologous to penis: Produces feelings of pleasure Composed of erectile tissue - Does not have a duct through it Prepuce: skin fold Covers & protects clitoris
Slide 28-

Female Glands Vestibular glands (aka. Bartholin’s glands) Located postero-lateral to the vaginal opening - homologous to bulbourethral glands Secretion: Mucus Function: vaginal lubrication & protection Mammary glands Modified sweat glands in the breast tissue Secretion: milk Functions: lactation: synthesis, secretion, and ejection of milk
Slide 29-

Trace the pathway from origin of sperm until it exits the male system Slide 16.2c Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings Figure 16.2
Slide 30-

Continue the sperm pathway until it meets the egg & implants in the uterus
