Is knee jerk a conditioned reflex?

A reflex is built into the nervous system and does not need the intervention of conscious thought to take effect. The knee jerk is an example of the simplest type of reflex.

What is the difference between conditioned and unconditioned reflexes?

These examples, and other reflexes typically present in normal animals or humans, are called “ unconditioned reflexes (URs).” The stimulus that elicits a UR is called the “unconditioned stimulus (US).” In contrast, a “ conditioned reflex (CR)” is a reflex that has been created or modified through a particular training.

Can reflexes be controlled or modified?

Your brain gets involved by modifying and fine-tuning reflex actions. For example, when you trip and fall, reflexes automatically command your hands and arms to reach out and break your fall. If the object in your hands is important enough to you, you can modify the reflex action and keep a grip on the vase.
