Perineal Boundaries

Answer 1

Lateral: Ischial tuberosity

Anterolateral: inferior pubic rami and ischial rami

Question 2

Triangles of the perineum

Answer 2

Anterior: Urogenital triangle

Posterior: Anal triangle

Question 3

Perineal Body

Answer 3

Central tendon of the perineum

Provides attachment for:

1. Bulbospongiosus muscle
2. Superficial and deep transverse perineal muscles
3. External anal sphincter

Question 4

Superficial Perineal Fascia (Female)

Answer 4

Fatty superficial (starts at levels of the skin) Labia majora to the Mons pubis and continued with Camper’s fascia

Membranous deep (Colles): Labia majora to the Scarpa’s fascia

Question 5

Superficial Perineal Fascia (Male)

Answer 5

Fatty superficial (scanty): Dartos’s muscle (scrotum) to the Campers fascia

Membranous deep (Colles): Dartos’s fascia to the Scarpas fascia

Question 6

Deep Perineal Fascia (Investing or Gallaudet’s fascia)

Answer 6

Both: invest ischiocavernosus, bulbosponginosis, and superfical transverse msucels

Male: Fused to deep (Buck) fascia of the penis and suspensory ligament (penis and clitoris)

Continuous with the deep fascia of the abdomen

Question 7

Male Superficial perineal pouch (urogenital triangle)

Answer 7

• Root (crura and bulb) of penis
• Ischiocavernosus muscle and Bulbosponginosus muscle (covers the root of the penis)
• The proximal part of the spongy urethra
• Superficial transverse perineal muscle
• Pudendal vessels and nerves

Question 8

Question 9

Male Deep Perineal Pouch

Answer 9

External urethral sphincter muscle (surrounds a membranous portion of the urethra; external sphincter of the urinary system)

Bulbourethral glands: lubricate urethra in males

Deep transverse perineal muscles

Pudendal vessels and nerves

Question 10
