Q1. Which attachment pattern best describes the superficial transverse perineal muscle?
- Iliac crest to femur
- Sacrum to pubic symphysis
- Ischial tuberosity to perineal body
- Coccyx to acetabulum
Q2. Which branch of the pudendal nerve carries motor fibers to the superficial transverse perineal muscle?
- Perineal nerve
- Inferior rectal nerve only
- Dorsal nerve of the penis or clitoris only
- Posterior femoral cutaneous nerve
Q3. Which structure is reinforced by bilateral contraction of the superficial transverse perineal muscles?
- Sacral promontory
- Inguinal ligament
- Perineal body
- Acetabular labrum
Q4. Why is stabilization of the perineal body functionally important?
- It directly controls hip rotation
- It generates urine in the kidneys
- It helps maintain support of the pelvic floor and perineum
- It produces intestinal peristalsis
Q5. Which superficial perineal muscle covers the crus of the penis or clitoris?
- Superficial transverse perineal
- Puborectalis
- Coccygeus
- Ischiocavernosus
Q6. Which superficial perineal muscle is associated with the bulb of the penis in males and bulbs of the vestibule in females?
- Bulbospongiosus
- Superficial transverse perineal
- Deep transverse perineal
- External anal sphincter
Q7. Which fascial layer forms the superficial boundary of the superficial perineal pouch?
- Endopelvic fascia
- Colles' fascia
- Thoracolumbar fascia
- Obturator fascia
Q8. Which structure forms the deep boundary of the superficial perineal pouch?
- Obturator membrane
- Sacrotuberous ligament
- Perineal membrane
- Pelvic brim
Q9. Which statement best distinguishes the superficial transverse perineal muscle from ischiocavernosus?
- It receives autonomic innervation only
- It lies within the anal triangle
- It primarily stabilizes the perineal body rather than compressing the crus
- It is smooth muscle rather than skeletal muscle
Q10. Which description best characterizes the course of the superficial transverse perineal muscle?
- Circularly around the anal canal
- Transversely from the ischial region toward the perineal body
- Vertically from the sacrum to the coccyx
- Longitudinally along the femoral shaft
