Female Reproductive Notes: Anatomy Final Notes – Female Reproductive System
Reproductive System Comparisons
Similarities
-Gonads located in the ovaries that produce:
-gametes
Differences
-all gametes are developed before you are born, males don’t start producing sperm till puberty
-male ejaculate several hundred million sperm, women ovulate one ovum
Reproductive Structures
Primary Sex Organs
-gonads (ovaries)
Secondary Sex Organs
-successful fertilization and development
-
Ovaries
-Upper pelvic cavity intraperitoneal
-
Attachments
Broad Ligament
-parietal peritoneum
Ovary – Internal Structure
Cortex – all of the developing follicles
Uterine Tubes
Ampulla – where the sperm and egg meet to make a zygote 9/10 times, occurs other places 1/10 times
Blood Supply
Ovarian Artery
-travels in the suspensory ligament of the ovary
-
Uterus – Gross Anatomy
Uterine Horn – where urterine tube enters
Cancer of the Cervix
-sixth most common disease in women
-slow growing disease
-
Uterine Wall
Perimetrium
-outer serous layer (same as visceral peritoneum)
-vesicouterine pouch (between bladder and uterus)
-
Vagina
Functions
-Excretory duct for passage of menses
The Grafenberg Spot (g-spot)
-an erogenous zone approx. 5 cm from the vaginal orifice
Vulva – External Genitalia
Mons Pubis
-anterior to pubic symphysis
-adipose tissue
-covers symphysis
-cushioning during colitis
Labia Majora
Mammary Glands
-modified sweat glands
-surface location:
Blood Supply
Internal Thoracic Artery
-
-branches off the axillary (same as subclavian just switches once armpit region)
Breast Cancer
-second-leading cause of death from cancer
The Breast
-four quadrants
-for anatomical location and description of tumours
Lymphatic Drainage
-Many nodes at axillary or parasternal or cervical
Female Sexual Arousal
-similar autonomic responses as males (parasympathetic for arousal than sympathetic)
-clitoris – engorges with blood
Oogenesis – Introduction
-development of the egg – begins when you are born
Fetal Period
Ovarian Cycle
-monthly series of events associated with maturation of an oocyte
-two phases:
Uterine Cycle
Menstrual Phase
-Days 1-5
-Uterus sheds most of endometrial lining
-Functionalis layer detaches from uterine wall resulting in bleeding
