Answer 61

Answer: C) Contributing to the formation of the sciatic nerve The anterior rami of the L1-L4 spinal roots divide into several cords. These cords then combine together to form the six major peripheral nerves of the lumbar plexus. These nerves then descend down the posterior abdominal wall to reach the lower limb, where they innervate their target structures. A useful memory aid for the branches of the lumbar plexus is: I, I Get Leftovers On Fridays. This stands for the Iliohypogastric, Ilioinguinal, Genitofemoral, Lateral cutaneous nerve of the thigh, Obturator and Femoral.

Answer 62

Answer: A) The internal oblique and transversus abdominis muscles And sits above the ilioinguinal nerve. The iliohypogastric nerve is the first major branch of the lumbar plexus. It runs to the iliac crest, across the quadratus lumborum muscle of the posterior abdominal wall. It then perforates the transversus abdominis, and divides into its terminal branches. Roots: L1 (with contributions from T12). Motor Functions: Innervates the internal oblique and transversus abdominis. Sensory Functions: Innervates the posterolateral gluteal skin in the pubic region. (Tip: an easy way to remember that the IlioHypogastric comes before the IlioInguinal is that H comes before I in the alphabet!)

Answer 173

Answer: B) Elevated diaphragm and decreased lung volumes. High diagram and mediastinum shift towards the effective lung Rationale: Vanishing lung syndrome, as mentioned in the context of systemic lupus erythematosus (SLE), is characterized by decreased lung volumes and an elevated diaphragm, which can be identified through imaging techniques such as X-rays. This condition contrasts with conditions like pneumothorax, where there's an increase in the space within the chest cavity. The syndrome may present with symptoms like dry cough, dyspnea, and recurrent atelectasis due to diaphragmatic weakness or phrenic neuropathy, which are not typical of standard pulmonary issues in SLE but represent a rare and severe manifestation.
