Скачать или смотреть Premed & Nursing students learning how to assess reflexes

In our anatomy and physiology lab this morning, my premed and nursing students dove into an engaging exploration of involuntary muscle contractions, specifically testing the knee-jerk (patellar) reflex to evaluate the reflex arc's functionality. The lab buzzed with excitement as students paired up to practice this classic clinical assessment on each other, blending hands-on learning with a few laughs.

How did they do it?

Students had their partner sit on a lab bench with their legs dangling freely to relax the muscles. They then located the patellar tendon, just below the kneecap, and used a reflex hammer to deliver a quick, gentle tap. A normal response triggered a swift forward kick of the lower leg, demonstrating an intact reflex arc involving the spinal cord and motor neurons.
