Pudendal (somatic)

14

Kehr's sign in the _______ is considered a classical symptom of ________.

-Left shoulder
-Ruptured spleen

15

Why is the pelvic outlet larger in females?

Due to EVERTED ISCHIAL TUBEROSITIES

16

1.) When is a culdocentesis indicated?
2.) Where is a culdocentesis performed? (i.e. behind and between what structures?)

1.) LQ and pelvic pain, and ectopic pregnancy or ovarian cyst.
2.) Posterior to the vaginal fornix, and near the midline between the uterosacral ligaments.

17

Describe the shapes of male and female pelvic inlets

Male = Heart-shaped
Female = Oval

18

Describe the shape of the obturator foramen in males and females

Males = round
Females = oval or triangular

19

1.) 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.

20

24

What is the location and contents (5 male, 1 female) of the superficial perineal pouch? Male and female

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).

26

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

27

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.
