Study Notes
Female Reproductive System Overview
- Pelvic inlet formed by the superior edge of the pubic symphysis, arcuate line of the ilium, anterior border of the ala, posterior border of the pubic crest, and sacral promontory.
- Pelvic outlet formed by the inferior edge of the pubic symphysis, inferior ramus of the pubis, ischial tuberosity, sacrotuberous ligament, and inferior end of the coccyx.
Bones of the Pelvis
- Acetabulum is the hip joint formed by ilium, ischium, and pubis, articulating with the femur.
- Hip joints are anteriorly joined by the midline pubic symphysis and posteriorly to the sacrum.
Shapes of the Pelvis
- Pelvic diaphragm comprises levator ani and coccygeus muscles, providing support against intra-abdominal pressure.
- Contains three apertures: urinary orifice, vaginal orifice, and anus; muscles relax during urination and defecation.
Pelvic Floor and Perineum
- Perineum is the sensitive area between the genitals and anus, aiding in urination, defecation, and copulation.
- Damage to the perineal body can weaken the pelvic diaphragm.
Pelvic Organ Prolapse
- Involves the bladder, uterus, and rectum bulging into the vagina, leading to various symptoms such as urinary incontinence and trouble starting urination.
- Common causes include childbirth and injury to pelvic support structures.
Internal Reproductive Organs
- Vagina: A distensible muscular tube, approximately 8 cm long, lined with mucosal epithelium, connecting to the cervix, which remains open due to sympathetic, parasympathetic, and visceral innervations.
- Uterus: A thick, hollow muscular organ capable of significant size changes during pregnancy. Its layers include the endometrium (inner lining), myometrium (muscle layer), and perimetrium (outer connective tissue).
Broad Ligament
- A flat sheet of peritoneum that supports the uterus, fallopian tubes, and ovaries, folding over the female genitalia.
- Mesometrium surrounds the uterus, mesovarium is associated with the ovaries, and mesosalpinx encloses the fallopian tubes.
Ovaries and Fallopian Tubes
- Ovaries: Almond-shaped, responsible for producing oocytes and reproductive hormones; mature oocytes develop into follicles.
- Fallopian Tubes: Each 4-5 inches long, with fimbriae capturing the ovulated ovum. Salpingitis refers to inflammation of these tubes.
Effects of Breathing on Pelvic Floor
- Kegel exercises strengthen pelvic floor muscles, providing support during activities that increase intra-abdominal pressure.
- Important for pelvic floor health and maintaining organ support.
