Practice questions
5 sample MCQs from this course. Tap a question to see the answer.
A 68-year-old male after radical prostatectomy presents with stress urinary incontinence. The physiotherapist plans pelvic floor muscle training. Which muscle forms the major component of the levator ani and is key for urethral support?
1. Which muscle of the pelvic floor is primarily responsible for maintaining urinary continence in males?
- A. Coccygeus
- B. Pubococcygeus
- C. Iliococcygeus
- D. Ischiococcygeus
Show answer
Answer: B. The pubococcygeus (including puboprostaticus in males) arises from the pubic bone and loops around the urethra, providing a sling that supports continence. Iliococcygeus and coccygeus are more posterior and less involved in urethral support.
A 50-year-old male is undergoing physiotherapy for perineal pain after a straddle injury. The therapist reviews the anatomy of the urogenital triangle. Which of the following forms the deep (superior) layer of the urogenital diaphragm?
2. Which structure forms the deep boundary of the urogenital triangle?
- A. Perineal membrane
- B. Colles' fascia
- C. Superficial transverse perineal muscle
- D. Ischiocavernosus muscle
Show answer
Answer: A. The perineal membrane is a thick triangular membrane that forms the deep boundary of the urogenital triangle, spanning the pubic arch. Colles' fascia is superficial, and the muscles are within the superficial pouch.
During a physiotherapy session for a 40-year-old male with chronic scrotal pain, the therapist reviews the anatomy of the spermatic cord. Which of the following is the correct tubular structure that transports sperm?
3. Which structure carries sperm from the epididymis to the ejaculatory duct?
- A. Vas deferens
- B. Epididymis
- C. Seminal vesicle
- D. Prostatic utricle
Show answer
Answer: A. The vas deferens is the muscular tube that carries sperm from the epididymis to the ejaculatory duct. The epididymis stores sperm, seminal vesicles produce fluid, and the prostatic utricle is a remnant.
A 75-year-old male with urinary retention has an indwelling catheter. He develops suprapubic pain and hematuria. The physiotherapist considers the anatomy of the bladder neck. Which region of the bladder is most sensitive and prone to irritation?
4. Which part of the bladder is most susceptible to irritation from a catheter?
- A. Dome
- B. Base (trigone)
- C. Apex
- D. Neck
Show answer
Answer: B. The trigone is a triangular area at the base of the bladder between the ureteric orifices and the internal urethral orifice. It is highly sensitive and often irritated by catheters. The dome is superior, apex is anterior, neck is the urethral opening.
A 35-year-old male sustains a pelvic ring fracture in a motor vehicle accident. Post-surgery, he presents with inability to dorsiflex the left foot. The physiotherapist identifies weakness in tibialis anterior. Which nerve is likely injured?
5. Which nerve is most likely compressed in a patient with foot drop after pelvic fracture?
- A. Obturator nerve
- B. Femoral nerve
- C. Common fibular (peroneal) nerve
- D. Sciatic nerve
Show answer
Answer: C. The common fibular nerve is a branch of the sciatic nerve and is vulnerable to compression in pelvic fractures or prolonged positioning. It innervates tibialis anterior for dorsiflexion. Obturator nerve adducts thigh, femoral nerve extends knee, sciatic nerve innervates hamstrings.
Flashcards
Which muscle forms the largest part of the pelvic floor and is crucial for continence?
The levator ani muscle, composed of pubococcygeus, iliococcygeus, and puborectalis, forms the main pelvic diaphragm. It supports pelvic organs, assists in fecal continence (especially puborectalis sling), and contracts during voluntary pelvic floor exercises. Weakness can lead to pelvic organ prolapse or incontinence.
What structures pass through the urogenital diaphragm in the male?
The urogenital diaphragm (perineal membrane) is pierced by the membranous urethra, ducts of bulbourethral glands, and branches of the internal pudendal vessels and pudendal nerve. It provides a sling of muscle (deep transverse perineal) that helps in ejaculation and urinary control.
What are the three zones of the prostate gland, and which is most commonly affected by carcinoma?
The prostate has peripheral, central, and transition zones. The peripheral zone (70% of gland) is the most common site for adenocarcinoma. The transition zone surrounds the urethra and is where benign prostatic hyperplasia (BPH) typically develops. The central zone is small and rarely involved in disease.
What is the function of the internal anal sphincter, and how does it differ from the external?
The internal anal sphincter is smooth muscle (involuntary) that maintains continuous contraction for fecal continence at rest. The external anal sphincter is skeletal muscle (voluntary) that provides additional squeeze during delayed defecation. The internal sphincter relaxes in response to rectal distention via the rectoanal inhibitory reflex.
Which part of the male urethra is most vulnerable to rupture during pelvic fracture?
The membranous urethra (1-2 cm) passing through the urogenital diaphragm is the most fixed and vulnerable segment. Shearing forces from pelvic fractures (especially pubic rami) can transect it at the urogenital diaphragm junction. This leads to urinary extravasation into the perineum and potential stricture formation.
