Doctor Johansson wants to test a patient's reflexes by briskly striking the patellar tendon with a reflex hammer. Which reflex is Dr. Johansson testing?

A) Golgi tendon reflex
B) Withdrawal reflex
C) Knee-jerk reflex
D) Crossed extensor reflex
E) Reciprocal innervation

Patellar Tendon

The tendon that connects the patella (kneecap) to the tibia (shinbone), playing a crucial role in the extension of the knee.

Reflex Hammer

A medical instrument used by practitioners to test deep tendon reflexes, aiding in the assessment of nervous system function.

Golgi Tendon Reflex

A protective reflex mechanism that prevents muscles from contracting excessively by inhibiting the muscle contraction when the tendon is under a high tension.
