anatomy Flashcards
gonadal - venous drainage
Left ovary/testis –> left gonadal vein –> left renal vein
–> IVC
Right ovary/testes –> right gonadal vein –> IVC
left vs right gonadal vein
Left –> left renal –> IVC
right –> IVC
gonadal vein - female vs male
female –> ovarian vein
male –> testicular vein (or spermatic vein)
clinical significance of speramatic vein
Because left spermatic vein enters the left renal vein at 90 degrees, flow flow is less laminar on left than right
–> more pressure on left vein –> varicocelle more common in left
varicocelle is more common in left or right side
left
Cervical, hilar, Mediastinal, Axillary lymph node cluster drains … (area)
cervical –> head and neck
hilar –> lungs
mediastinal –> Trachea and esophagus
axiallary –> Upper limb, breast, skin above umbilicus
Celiac lymph node cluster drains … (area)
liver, stomach, spleen, pancreas, upper duodenum
Superior mesenteric lymph node cluster drains … (area)
lower duodenum, jejunum, ilieum, colon to splenic fructure
Inferior mesenteric lymph node cluster drains … (area)
colon from splenic flexure to upper rectum
Para-aortic lymph node cluster drains … (area)
- Testes
- ovaries
- kidneys
- uterus
internal iliac nodes drain
- lower rectum to anal canal (above the line)
- cervix
- corpus carvenosum
- vagina (middle third)
- prostate
superficial inguinal drain
- anal canal (below the line)
- skin below umbilicus (except popliteal area)
- scrotum
- vulva
- vagina (lower third)
deep inguinal nodes
glans penis
external iliac nodes
- body of uterus
- cervix (and upper third of vagina)
- superior bladder
cervix lymph drainage
external and internal iliac nodes
uterus lymph drainage
Para-aortic external iliac (body)
lymph drainage - uterus, cervix, vagina
para-aortic uterus –> uterus
external iliac –> body of uterus, cervix, upper third vagina
internal iliac –> cervix, middle third vagina
superficial inguinal –> lower third vagina
Lymphatic drainage of the vagina is generally to the
external iliac nodes (upper third of the vagina), internal iliac nodes (middle third), and the superficial inguinal nodes (lower third).
Fenale reproductive system - ligaments
- infundibulopelvic ligament (suspensory ligament of the ovary)
- Cardinal ligament
- Round ligament of uterus
- Broad ligament
- Ovarian ligament
- uterosacral
Fenale reproductive system - ligaments an what they connect
- infundibulopelvic (suspensory ligament of the ovary) –> ovaries to lateral pelvic
- Cardinal –> cervix to side wall of pelvis
- Round ligament of uterus –> uterine fundus to labia major
- Broad –> uterus, fallopianm tuves and ovaries to pelvic side wall
- Ovarian –> madian pole of ovary to lateral uterus
- uterosacral –> uterus to the anterior aspect of the sacrum
infundibulopelvic ligament is AKA
suspensory ligament of the ovary
infundibulopelvic (suspensory ligament of the ovary) connects
ovaries to lateral pelvic
infundibulopelvic (suspensory ligament of the ovary) contains
ovarian vessels
cardinal ligament connects
cervix to side wall of pelvis
cardinal ligament contains
uterine vessels
Round ligament of the uterus connects
uterine fundus to labia majora
Round ligament of the uterus contains
nothing
Broad ligament connects
uterine, fallopian tubes and ovaries to pelvic side wall
Broad ligament contains
ovaries, fallopian tuves, round ligaments of uterus
uterosacral ligament connects
uterus to the anterior aspect of the sacrum
ovarian ligament connects
medial pole of ovary to lateral uterus
ovarian ligament contains
nothing
Derivatives of gubernaculum in females
- ovarian ligament
2. round ligament of the uterus
course of round ligmament of the uterus
travels along inguinal canal, in the broad ligament, above the artery of Sampson
Sampson artery
- runs under the round ligament of uterus.
- is anastomosis of the uterine artery and ovarian artery
Broad ligament - structure
Fold of peritoneum that comprises the
- mesosalpinx
- mesometrium
- mesovarium (suspends the ovaries)
ureter course in females
retroperotoneally, close to gonadal vessels (risk at injury during ligation of ovarian vessels) and under uterine artery)
(risk at injury during ligation of ovarian or uterine vessels)
an operation with uterine vessels ligation
hysterectomy
clinical correlation of infundibulopelvic ligament
- very close to ureter –> risk of injury during ligation
2. ligate vessels during oophorectomy to avoid bleeding
vagina histology
stratified squamous epithelium, nonkeratinized
ectocervix histology
stratified squamous epithelium, nonkeratinized
transformation zone (female reproductive) histology
Squamocolumnar junction (ectocervic-endocervix)
endocervix histology
simple columnar epithelium
uterus histology
simple columnar epithelium with long tubular glands in proliferative phase
coiled glands in secretory phase
fallopian tube histology
simple columnar epithelium, ciliated
ovary, outer surface histology
simple cuboidal epithelium (germinal epithelium covering surface of ovary
uterus walls
inside –> endometrium
middle –> myometrium
outside –> Perimetrium
perimetrium?
Serous layer of visceral peritonium. It covers the outer surface of the uterus
ovarian artery arises from
abdominal aorta (above L2)
uterine artery arises from
anterior division of the internal iliac artery
ovarian and uterine anastomosis
Sampson artery
portions of cervix
- endocervix
- transitional zone
- ectocervix
cervical os?
- external os: the external opening into the vagina
2. internal os: theinternal opening into the endometrial cavity
Vaginal fornix (fornices of the vagina)
superior portions of the vagina, extending into the recesses created by the vaginal portion of cervix
- posterior - behind the cervix (largest)
- anterior
- twο lateral
