Which layer of the abdominal wall is incised last before entering the peritoneal cavity?
Answer: Peritoneum
The peritoneum is the innermost layer of the abdominal wall and is entered last to access the peritoneal cavity.
The celiac trunk is the first major branch of the abdominal aorta and supplies blood to which organs?
Answer: Stomach, liver, and spleen
The celiac trunk branches into the left gastric, splenic, and common hepatic arteries, supplying the stomach, liver, and spleen.
Which nerve is at risk during a total hip arthroplasty due to its proximity to the posterior hip capsule?
Answer: Sciatic nerve
The sciatic nerve passes posterior to the hip joint and is the most commonly injured nerve during posterior approach total hip arthroplasty.
The mitral valve separates which two cardiac chambers?
Answer: Left atrium and left ventricle
The mitral (bicuspid) valve is located between the left atrium and left ventricle, preventing backflow during ventricular systole.
Which structure passes through the carpal tunnel alongside the flexor tendons?
Answer: Median nerve
The median nerve passes through the carpal tunnel with the flexor digitorum superficialis and profundus tendons and flexor pollicis longus tendon.
The ureters enter the bladder at an oblique angle to create a valve-like effect that prevents:
Answer: Vesicoureteral reflux
The oblique insertion of the ureters through the bladder wall creates a flap valve mechanism that prevents vesicoureteral reflux during micturition.
Which cranial nerve provides motor innervation to the muscles of mastication?
Answer: Cranial nerve V (Trigeminal)
The mandibular branch of the trigeminal nerve (CN V3) provides motor innervation to the masseter, temporalis, and pterygoid muscles.
