- ) Superior rectal
2. ) Inferior rectal
What is venous drainage for anal canal:
- ) Above pectinate
- ) Below pectinate

- ) Internal venous plexus –> inferior rectal vein –> caval system
What supplies pain sensation for anal canal below pectinate?
Pudendal (somatic)
Kehr’s sign in the _______ is considered a classical symptom of ________.
- Left shoulder
- Ruptured spleen
Why is the pelvic outlet larger in females?
Due to EVERTED ISCHIAL TUBEROSITIES
- ) When is a culdocentesis indicated?
2. ) Where is a culdocentesis performed? (i.e. behind and between what structures?)
- ) LQ and pelvic pain, and ectopic pregnancy or ovarian cyst.
- ) Posterior to the vaginal fornix, and near the midline between the uterosacral ligaments.
Describe the shapes of male and female pelvic inlets
Male = Heart-shaped Female = Oval
Describe the shape of the obturator foramen in males and females
Males = round Females = oval or triangular
- ) Females typically have what type of pelvic girdle?
2. ) Compare it anthropoid and platypoid in terms of AP and lateral landmarks and shape
1.) Gynecoid: Oval-shaped.
2.) Anthropoid: longer sacrum to pubic symphysis. Narrow heart shaped.
Platypelloid: Longer distance between ischial spines. Wide heart shaped.
What three landmarks are wider in a female pelvis?
Sacrum, subpubic angle or pubic arch, greater sciatic arch.
What is the blood supply for the superior and inferior vagina?
Superior: Uterine
Inferior: Vaginal
1.) What is the blood supply to the rectum in males (proximal, middle, inferior). Anal canal and anorectal junction?
1.) Proximal = Superior rectal. Middle and inferior = Middle rectal arteries. Anal canal and junction = Inferior rectal arteries.
1.) What supplies blood to the anterosuperior parts of the bladder?
2.) Fundus and neck?
3.) Posteroinferior
Give answers for both male and female
1.) Males and females: Superior vesical
2.) Males: Inferior vesical
Females: Vaginal arteries
3.) Same as #2
What is the location and contents (5 male, 1 female) of the superficial perineal pouch? Male and female
Location: Between Colles’ fascia and the inferior fascia of UG diaphragm.
Contents: Mnemonic –> Great Vest BITCh = Greater vestibular glands (females), Bulb of penis and bulbospongiosus, Ischiocavernosus muscle, superficial Transverse perineal muscle, Cowper’s gland (males)
- ) What are the superior and inferior borders of the deep perineal pouch?
- ) Contents – male (5) and female (4)
1.) Inferior: Perineal membrane (aka inferior fascia of UG diaphragm)
Superior: Superior fascia of UG diaphragm
2.) Males: Intermediate/membranous part of urethra (narrowest part, MALES only), deep transverse perineal muscle, sphincter urethrae (inferior to prostate), bulbourethral glands, branches of internal pudendal vessels and nerves.
Females: Mass of smooth muscle (instead of deep transverse perineal, FEMALES ONLY), sphincter urethrae (distal inferior end in females), branches of pudendal vessels and nerves. UG diaphragm (FEMALES ONLY).
What are the narrowest and widest part of the male urethra?
Narrowest: Intermediate/membranous part (distal to prostatic, proximal to spongy) except for the EXTERNAL URETHRAL ORIFICE
Widest: Prostatic urethra
Pudendal nerve block: Where to inject and how to find? Caudal anesthesia?
Palpate ischial spine –> insert needle in direction of tip of finger through the POSTEROLATERAL VAGINAL WALL, just BENEATH the PELVIC DIAPHRAGM and toward the ischial spine – thus, locating the PUDENDAL NERVE. Can be done sub-q through buttock, on medial on medial side of ischial tuberosity
-CAUDAL is done slightly higher (sacral canal) and anesthetizes SUBPERITONEUM plus somatic pudendal distribution (popular for childbirth) <– S2-S4 spinal nerves. Must be done BEFORE actual delivery.
