1
Perineum
- Diamond shaped area
- Between Medial thighs
- Anterior to sacrum and coccyx
- Line divides into:
- anterior- urogenital triangle
- Posterior-anal triangle
- anterior- urogenital triangle
- Posterior-anal triangle
2
Urogenital Triangle
- Homologous structure between female and males
- develop from embryonic primordia
- Females:
- Bilateral Primordia
- except midline cleft
- Males:
- bilateral primordia fused into midline structures
- develop from embryonic primordia
- Bilateral Primordia
- except midline cleft
- bilateral primordia fused into midline structures
3
Female External Genitals (Vulva)
- Labia Majora
- Labia Minor
- Vestibule of Vagina
- Clitoris
- Vestibule of Vagina
4
Labia Majora
- homologue to scrotum
- 2 prominent longitudinal folds
5
Labia Minor
- homologue to ventral surface of penis
- 2 smaller folds
- medial to labia majora
6
Vestibule of Vagina
- cleft b/w labia minora
- urethra, vagina, and ducts of various glands open into
7
Clitoris
- homologue to penis
- mobile body (ending in glans) and attached to root
- composed of 3 cylindrical bodies of erectile tissue
8
Male External genitals
- Scrotum
- Testis
- Epididymis
- Ductus (Vas) Deferens
- Penis
9
Scrotum:
- homologue to labia majora
- pouch containing:
- testes
- epididymides
- distal part of ductus deferns
- Scrotal Wall is continuation of superficial abdomiinal fascia
- contains smooth muscle fibers (dartos muscle)
- cold temperatures contract
- testes
- epididymides
- distal part of ductus deferns
- contains smooth muscle fibers (dartos muscle)
- cold temperatures contract
10
Testis
- homologue to ovary
- suspended in scrotum by spermatic cord
- efferent ductules transport sperm to epididymis
11
Epididymis
- Cap-like structure
- superior and posterior to testis
- stores sperm as they mature
12
Ductus (Vas) Deferens
- located posterior in spermatic cord
- Ascends scrotum and passes through
- superficial inguinal ring
- abodminal wall
- superficial inguinal ring
- abodminal wall
13
Penis
- homologue to clitoris
- has
- mobile body (Shaft)
- attached root,
- prepuce (Fore-skin)
- glans containing external urethal orifice
- Composed of 3 cylindrical bodies (Corpora) of erectile tissue
- paired corpora cavernosa
- dorsum of penis
- single corpus spongiosum
- contain spony urethra
- expands distally to form conical glans
- mobile body (Shaft)
- attached root,
- prepuce (Fore-skin)
- glans containing external urethal orifice
- paired corpora cavernosa
- dorsum of penis
- single corpus spongiosum
- contain spony urethra
- expands distally to form conical glans
14
Deep Perineal Pouch
- Superior to perineal membrane & superficial perineal pouch
- adjacent to pelvic diaphragm
15
Male deep perineal pouch contains
- intermediate (membranous) urethra
- External urethral sphincter
- Bulbourethral glands
16
Bulbourethreal glands
homologue to greater vestibular glands
17
Female Deep Perineal Pouch contains
- urethra
- external urethral sphincter
- vagina
18
Blood Supply of Urogenital Triangle
- Internal pudental artery branches (branch of internal iliac)
- superficial and deep perineal pouches
- external genitals
- Penile Bulb Artery (Vestibular Bulb)
- bulb
- corpus spongiosum
- Deep Artery of Penis/Clitoris
- corpus cavernosum
- Dorsal artery of penis/clitoris
- shaft
- glans
- superficial and deep perineal pouches
- external genitals
- bulb
- corpus spongiosum
- corpus cavernosum
- shaft
- glans
