Which of these is a type of stretch/deep tendon reflex?

The ankle jerk reflex is a type of stretch deep tendon reflex. This reflex is elicited by tapping the Achilles tendon just above the heel, which leads to a brief stretch of the calf muscles. The sensory receptors in the muscle detect this stretch and send signals to the spinal cord, where they synapse with motor neurons. The motor neurons then initiate the contraction of the calf muscles, causing a quick and involuntary extension of the ankle joint. This reflex helps maintain posture, balance, and coordination by stabilizing the lower limbs when standing and walking.
