Question 1

Venous drainage

Answer 1

left ovary/testis –> left gonadal vein –> left renal vein –> IVC

right ovary/testis –> right gonal vein –> IVC

Question 2

Lymphatic drainage of ovaries and testes

Answer 2

para-aortic lymph nodes

Question 3

Lymphatic drainage of distal vagina/vulca/scrotum

Answer 3

superficial inguinal nodes

Question 4

Lymphatic drainage of proximal vagina and uterus

Answer 4

obturator, external iliac and hypogastric nodes

Question 5

Infudibulopelvic ligament (suspensory ligament of ovaries)

connects: the ovaries to the pelvic wall
contains: ovarian vessles

Notes: ligate vessels during oophorectomy to avoid bleeding, the ureter is at risk of unjury during ligation as it close to the gonadal vessels

Answer 5

Question 6

cardinal ligament

Answer 6

connects: cervix to side wall of pelvis
contains: uterine vessels
notes: ureter is at risk during ligation of uterine vessels in hysterectomy

Question 7

round ligament of the uterus

connects: uterine fundus to labia majoria
notes: derivitive of the gubernaculum, travels through round inguinal canal; above the artery of sampson

Answer 7

Question 8

Broad ligament

• mesosalpixm, mesovarium, mesometrium
  connects: uterus, fallopian tubes and ovaries to the pelvic SIDE WALL
  contains: ovaries, fallopian tubes, round ligaments of uterus

Answer 8

Question 9

Ovarian ligament

connects: the ovary to the lateral uterus
note: derivative of the gubernaculum.

Answer 9

Question 10

Vagina

stratified squamous epithelium, non keratinized

Answer 10

Question 11

Ectocervix

stratified squamoys epithelium, non keratinized

Answer 11

Question 12

endocervix

stratified columnar epithelium

Answer 12

Question 13

Transformation zone

squamocolumnar junction (most common area for cervical cancer)

Answer 13

Question 14

Uterus

-siimple columnar epithelium with long tubular glands

Answer 14

Question 15

Fallopian tube:

simple columnar epithelium, many ciliated cells, few secretory (peg) cells

Answer 15

Question 16

Ovary, outer surface: simple cuboidal epithelium (germinal epithelium covering surface of ovary)

Answer 16

Question 17

Female sexual response

Answer 17

autonomic nervous system

Question 18

male sexual response

Answer 18

parasympathetic nervous system point and shoot

pelvic nerve:

-NO –> increase cGMP –> smooth muscle relaxation –> vasodialtion –> proerectile, as blood flows is

NE–> increase Ca intracellular –> smooth muscle contraction –> vasoconstriction –> antierectile

emission: sympathetic nervous system (hypogastric nerve)
ejaculation: visceral and somatic nerves (pudendal)

Question 19

male reproductive anatomy

Answer 19

Question 20

seminiferous tubules

Answer 20
