Intermediate Perineal Fascia Quiz

Q1. Why does fluid in the superficial perineal pouch generally not spread posteriorly into the anal triangle?

• Colles fascia is attached posteriorly to the perineal membrane and perineal body
• The anal triangle is completely surrounded by bone
• The urethra blocks all posterior movement
• The bladder absorbs the fluid

Q2. Why does fluid within the superficial perineal pouch generally not descend into the thigh?

• The thigh contains no superficial fascia
• The obturator nerve blocks the pathway
• The membranous superficial fascia attaches to the fascia lata
• The femoral artery prevents its passage

Q3. Fluid from the superficial perineal pouch can spread into the lower anterior abdominal wall through continuity with which fascia?

• Transversalis fascia
• Prevertebral fascia
• Endothoracic fascia
• Scarpa fascia

Q4. What forms the inferior boundary of the deep perineal pouch?

• Skin
• Colles fascia
• Dartos fascia
• Perineal membrane

Q5. Which fascial layer is directly superficial to the contents of the superficial perineal pouch?

• Endopelvic fascia
• Colles fascia
• Obturator fascia
• Peritoneum

Q6. Which statement correctly describes the relationship between Scarpa fascia and Colles fascia?

• Both form the pelvic diaphragm
• They are continuous membranous fascial layers
• Both are layers of peritoneum
• They are separated completely by the inguinal ligament

Q7. Which deep fascial layer surrounds the corpora cavernosa and corpus spongiosum of the penis?

• Colles fascia
• Buck fascia
• Scarpa fascia
• Camper fascia

Q8. Which structure separates the superficial and deep perineal pouches?

• Parietal peritoneum
• Camper fascia
• Dartos fascia
• Perineal membrane

Q9. What happens to the superficial fatty layer of fascia within the scrotum?

• It becomes hyaline cartilage
• It is largely replaced by dartos smooth muscle
• It forms the tunica vaginalis
• It becomes the cremaster muscle

Q10. Which fascial relationship is most important in determining the spread of urine after injury to the spongy urethra?

• Attachments and continuities of the membranous superficial fascia
• Attachments of the pleura
• Structure of the mesentery
• Arrangement of the cranial meninges
