Arteries of Pelvis and Perineum
Abdominal Aorta Common iliac arteries (L4)
External iliac artery Inferior epigastric artery Deep circumflex iliac artery
Arteries of Pelvis and Perineum
Abdominal Aorta Common iliac arteries
Internal iliac artery Posterior division
Iliolumbar artery Superior gluteal artery Lateral sacral arteries
Arteries of Pelvis and Perineum
Internal iliac artery Anterior division
Obturator artery Umbilical artery Vaginal/uterine artery Inferior vesical artery Middle rectal artery Internal pudendal artery Inferior gluteal artery
Muscles of Pelvis
Piriformis muscle Obturator internus muscle Coccygeus muscle Levator ani muscles
Iliococcygeus muscle Pubococcygeus muscle Puborectalis muscle
Muscles of Perineum
Ischiocavernosus muscle Bulbospongiosus muscle Sphincter urethrae muscle Deep transverse perineal muscle Superficial transverse perineal muscle
Ligaments of Pelvis
Sacrotuberous ligament Sacrospinous ligament Suspensory ligament of ovary Proper ligament of ovary Broad ligament
Mesometrium Mesovarium Mesosalpinx
Ligaments of Pelvis
Round ligament of uterus Cardinal ligament - uterine vessels
Nerves of Pelvis and Perineum
Lumbosacral trunk (L4, L5) Sacral plexus - ventral rami of S1, S2, S3 and
S4 Pudendal nerve (S2, S3, S4)
Perineal nerve Inferior rectal nerve Dorsal nerve of clitoris or penis
Obturator nerve (L3, L4) Inferior gluteal nerve (L5, S1, S2) Superior gluteal nerve (L4, L5, S1)
Veins of Pelvis and Perineum
Inferior vena cava (L5) Common iliac veins Internal iliac veins External iliac veins (femoral vein) Testicular or ovarian veins (left or right)
Female Organs
Infundibulum of uterine tube Fimbriae Ampulla of uterine tube Isthmus of uterine tube Uterine part Uterus
Fundus Body Internal os
Female Organs
Cervix Internal os External os
Vagina Fornices Vestibule
Vulva
Male Organs Scrotum
Skin Superficial (Dartos’) fascia External spermatic fascia Cremaster muscle Internal spermatic fascia
Testis Tunica vaginalis - parietal and visceral
layers Epididymis Tunica albuginea - seminiferous tubules
Male Organs
Ductus (vas) deferens Seminal vesicles Prostate
Ejaculatory ducts Lobes
Middle - benign prostatic hypertrophy (BPH)
Posterior - cancer prone
Male Organs
Corpus caverosum (corpora cavernosa) Corpus spongiosum Prostatic urethra Membranous urethra Spongy urethra
Male and Female Pelvis
Sacrum Ischial tuberosities Shape of pelvic inlet Pelvic inlet to pelvic outlet Pubic arch Size of pelvic cavity
Perineum
Boundaries Anal triangle Urogenital triangle
Urinary Bladder
Posterior of retropubic space Apex is anterior Ureters enter bladder posteroinferior Trigone - orifices of ureters and uvula of
bladder Interureteric crest Vesicouterine pouch - female Rectovesical pouch - male
Rectum
Arterial supply Superior rectal artery Middle and inferior rectal arteries
Venous drainage Superior rectal vein Middle and inferior rectal veins
Anus Anal columns Anal valves Pectinate line
Upper half and lower half of anal canal joins Differences
Epithelium (SCE, SSE) Anal columns Nervous innervation Arterial supply (SRA, IRA) Venous drainage (SRV, IRV) Lymphatic drainage
