Parasympathetic and sympathetic innervations of the rectum
(para) S2-S4
(Symp) T12 & L1
Location where rectum begins
At the level of S3
Point where rectum ends
Anorectal junction
Transverse rectal folds are composed of
(1) mucosal membrane
(2) circular muscle layer
Temporary Rectal Folds
longitudinal folds that disappear upon distention
Location of the Female Ureters
From kidneys goes down & enters pelvic brim
* infront of the bifurcation of the common iliac artery
* backward along the internal iliac artery
* behind ovaries
* under uterine artery
* forward entering the post. urinary bladder lateral to the
vagina
3 constrictions of the ureter
(1) from renal pelvis to start of ureter
(2) as it enters pelvic brim
(3) as it joins bladder
Maximum capacity of the urinary bladder
500mL
Urinary bladder shape when empty
pyramidal
Muscle of the urinary bladder and its sphincter
Detrusor muscle and sphincter vesicae
Peritoneal pouch in between the superior portion of the urinary bladder and the uterus
Uterovesical pouch
Connects the lateral wall of the uterus to the ovary; represents the remains of?
- round ligament of the ovary
- upper part of the gubernaculum
The pelvic depression where the ovary lies; boundaries?
ovarian fossa
bounded by the external iliac artery above and the internal iliac vessels behind
fibrous capsule of the ovary
Tunica albuginea
Modified peritoneum that covers the capsule of the ovaries
germinal epithelium
Where does fertilization of the ovum usually take place?
The ampulla of the uterine tube
uterus shape
pear-shaped
(1) part of the uterus above the entrance of uterine tubes
(2) below the entrance of uterine tubes
(3) low, narrow part that pierces the anterior wall of the vagina
(1) fundus
(2) body
(3) cervix
2 parts of the cervix
(1) supravaginal
(2) vaginal parts of the cervix
mucous membrane lining of the uterus
endometrium
visceral pelvic fascia surrounding the supravaginal part of the cervix
parametrium
positions of the uterus
anteversion, anteflexion, retroversion, retroflexion
3 fascial ligaments of the female pelvic wall
(1) transverse cervical
(2) pubocervical
(3) sacrocervical
Female Genital Organs
(1) Ovary
(2) Uterine tube / Fallopian tube
(3) Uterus
(4) Vagina
Menstrual Cycle Length
Normal Range 23 to 35 days
Average cycle length 28 days
secure ovary to the lateral wall of the pelvis
suspensory ligaments
attach the ovary to the uterus (for support only - nonfunctional)
ovarian ligament
Ovarian artery arises at what level
L1
Ovarian veins drain to
(R) Inferior vena cava
(L) left renal vein
Layers of the Uterine wall
- Perimetrium - outer serous membrane
- Myometrium - middle muscle
- Endometrium - inner mucosal lining
Provides main support for the cervix and uterus, found at the base of the broad ligament
cardinal ligament or Transverse cervical ligament
Play a minor role in supporting the uterus
Broad ligament & Round ligament
Parts of the broad ligament
*Mesovarium
*Mesometrium
*Mesosalpinx
