Round 10: Tossup 11

Note to moderator: Read the answerline carefully. Damage to three structures in this body part make up O’Donoghue’s unhappy triad. In Osgood–Schlatter disease, (10[2])a painful bump directly (10[1])below this body part is caused by epiphyseal plate (10[1])tension during growth (10[1])spurts. When extended (10[1])by the vastus medialis, this body part is stabilized by the screw-home mechanism and by posterior and anterior ligaments arranged in an “X” shape. The menisci of this joint improve (10[1])its shock absorption capacity. This joint’s soft cartilage hardens into bone at age (10[1])four and connects the femur and tibia. For 10 points, a common reflex test involves striking the patella of what largest joint located between the shin and thigh? ■END■

ANSWER: knees [accept kneecaps; accept medial knees or inner knees; accept blown knees; prompt on patellas or patellar tendon until “joint” is read; prompt on meniscus or menisci until “menisci” is read; prompt on anterior cruciate ligaments or ACLs or posterior cruciate ligaments or PCLs or medial collateral ligaments or MCLs until “joint” is read; prompt on legs until “joint” is read; prompt on tibiofemoral joints or patellofemoral joints] (The posterior and anterior cruciate ligaments are named for their cross-shape.)
