Which structure is the sickle-shaped process?

Which structure is the sickle-shaped process?

• A. Psoas major
• B. Opponens pollicis
• C. Peroneal artery
• D. Falciform process

Answer: (D)

Falciform means sickle-shaped, and in anatomy the falciform process refers to the curved peritoneal fold that forms the falciform ligament of the liver. Its shape is the reason it’s described as sickle-shaped. The other options are a lumbar muscle (psoas major), a hand muscle (opponens pollicis), and a leg artery (peroneal artery), none of which are described as sickle-shaped projections.
