Clinical Anatomy Of The Reproductive System Flashcards
Where is the pelvic cavity located
Within the bony pelvis
Between pelvic inlet and outlet
What is the pelvic floor
Internal wall of skeletal muscle
Separates pelvic cavity and perineum
What is the perineum
Between proximal parts of lower limbs
Where can reproductive and renal tracts pass through
Openings in the pelvic floor
What is the pelvic roof formed by
Parietal peritoneum
What is the function of the parietal peritoneum
Lines abdominal cavity
Drapes over pelvic viscera
What can form via peritoneum in the female reproductive system
Vesico-uterine pouch
Rectouterine pouch
Catches fluid
What are secondary female reproductive organs
Uterine tubes
uterus
Vagina
What are the 3 layers of the body of the uterus
Perimetrium
Myometrium
Endometrium
What is the function of the fimbriae of the uterine tube
Finger like, catch eggs from peritoneal cavity released from ovaries
What is the most common position of the uterus
Anteverted and anteflexed
How is the cervix anteverted
Tipped anteriorly relative to the vagina
How is the uterus anteflexed
Tipped anteriorly to the cervix
Rests on bladder
Where does the ovaries develop
On the posterior abdominal wall and move onto lateral wall of the pelvis
What is the function of the ovaries
Secrete oestrogen and progesterone in response to pituitary hormones
What vessels of the ovaries also develop on the anterior abdominal wall and move down to the pelvic cavity
Lymphatic drainage
Venous drainage
Arterial supply
What are the main arteries found in the female pelvis
Ovarian artery
Internal iliac artery
Uterine artery
Common iliac artery
Vaginal artery
Which artery supplies most of the organs in the pelvis and peirneum
Internal iliac artery
Where is the ovum released into
Peritoneal cavity
Where is the ovum gathered
By fimbriae into infundibulum of the uterine tube
How is the ovum moved along the uterine tube
Cilia
How is an unfertilised ovum expelled during menstruation
By contractions of the myometrium
Where does fertilisation usually occur
Ampulla
What is an ectopic pregnancy
Fertilised ovum implants outwith the uterine cavity
Why is the urethra of the penis a common final pathway
Urine and semen excreted from same external orifice
Where do testes originate during development
Posterior wall of abdominal cavity
Where do testes descend to the scrotum through
Inguinal canal
Where does the vas deferens originate
Posterior wall of abdomen
Where are sperm produced
Seminiferous tubules
What is the function of the rete testis
Net like structure to gather sperm
What does the spermatic cord contain
Vas deferens
Testicular artery
Pampiniform plexus of veins
What can torsion (twisting) of the testes lead to
Disrupted blood supply
Pain
Danger of testicular necrosis
Where does the sperm meet the seminal fluid
Ejaculatory duct (opening) where vas deferens meets seminal gland
What are the functions of the prostatic urethra
Found in prostate
Drain urine from bladder
Passes semen during ejaculation
What structure is found inferior to the prostatic urethra
Spongy urethra
Pelvic floor
How is an erection formed
3 cylinders of erectile tissue become filled with blood at arterial pressure
What are the male accessory reproductive organs
Vas deferens
Seminal glands
Prostate gland
Penis
Where does each vas deferens lie within
Spermatic cord
Which structure does each spermatic cord pass through to reach the pelvic cavity
Through the anterior abdominal canal within the inguinal canal
Where do the right and left ejaculatory ducts join together
Prostate gland
