Pelvis Flashcards
Nerve supply of gluteus Maximus
Inferior gluteal
Nerve supply of gluteus medius/minimus
Superior gluteal
Largest nerve in the body (L4-S3)
Sciatic n
Lesion of superior gluteal nerve
Waddling gait
Branches of pudendal nerve
Inferior rectal
Perineal n
Location of kidney
Retroperitoneal
T12-L3
Renal hilum
Renal v
Renal a
Renal pelvis-posterior
Coverings of the kidney
Fibrous capsule- most internal
Perirenal fat
Renal fascia- kidney+suprarenal glands
Pararenal fat- most external
Ureter:relations
Male: crossed by vas deferens
Female: medially beneath broad ligament crossed by uterine artery
During THABSO, location of ureter
Lies medial to ovarian vessels
Inferior to uterine vessel
Lateral to uterine cervix
Ureteric constrictions
Renal pelvis joins the ureter
Ureter crosses he pelvic brim and external iliac a
Pierces the bladder wall
Referred pain of renal colic
T11, L2 dermatomes
Inferolateral border of the urinary bladder
Retzius space
Smooth muscle of the urinary bladder
Detrusor muscle
Trigone
3 openings
- 2 from ureter
- 1 from urethra
Has direct/indirect contribution to development of genital system
Mesonephron/ Wolffian duct
Will become permanent kidney
Metanephrons- ureteric bud (ureter, RP, RC, CT) and metanephric tubule (nephron)
Fates of the UG sinus
Vesical- urinary bladder
Pelvic- urethra (prostatic urethra in males)
Phallic- genital tubercle
3 zones of medulla
Glomerulosa: mineralocorticoid
Fasciculata: cortisol ( inc cortisol, dec FSH)
Reticulata: cortisol (dec cortisol, inc FSH)
Male vs Female urethra
Male: 8 in/ 20cm (prostatic, membranous, penile)
Female: 1.5 in/ 3.8 cm
Pelvic brim/ inlet
Ant: symphysis pubis
Lat: iliopectineal line
Post: sacral promontory
Pelvic outlet
Ant: pubic arch
Lat: ischial tuberosities
Post: tip of coccyx
Divides sciatic notches to greater and lesser sciatic foramen
Sacrotuberous and sacrospinous lig
Perineal body
Bulbospongiosum, external anal sphincter, superficial/deep transverse perineal ms
Ischioanal fossae
Base: skin overlying anal triangle
Lateral: obturator internus muscle and fascia
Medial: elevator ani
Perineal fascia
Superficial (fatty layer, Colle’s fascia)
Deep/perineal fascia
Structures of the deep urethral space
Male: bulbourethral gland, internal pudendal vessels, membranous urethra, sphincter urethra, deep transverse urethral ms
Female: urethra, vagina, internal pudendal vessel, dorsal nerve of clitoris, sphincter urethra ms, deep transverse perineal ms
Branches of pudendal n.
Inf rectal- perianal skin, ext anal sphincter, mucous membrane (lower anal canal)
Dorsal n of penis/ clitoris
Perineal - perineal muscles/ skin
Sex is determined at __ week
7th week
Prior to 7th week- indifferent stage of sexual development
Gonadal sex determined by
Testes dear inning factor found in Y chromosome
Musculine differentiation of mesonephric duct
Testosterone
Produced by Leydig cells
Produces anti mullein hormone, inhibits development of paramesonephric duct
Sertoli cells
Dormant oocytes (arrested oogenesis, prophase, meiosis 1)
Primary
Arrested at metaphase of meiosis II
Secondary oocytes
Complete meiosis II
Fertilization
Length of vas deferens
18 in/45 cm
Secretion of alkaline phosphatase by
Seminal vesicle
Lobes of prostate gland
5 lobes Anterior Median Posterior 2 lateral
Length of uterine tubes
4”/10cm
Version
Uterus (fundus) on long axis of vagina
Flexion
Long body of uterus along cervix
