knee-jerk reflex
The knee-jerk reflex is a type of stretch reflex, which is a type of spinal reflex. It involves the stimulation of sensory neurons in the muscle spindles of the quadriceps muscle, leading to a quick contraction of the muscle in response to a sudden stretch.
Reflex
The statement "The patellar knee jerk reflex is controlled by the brain" is not correct. The patellar knee jerk reflex is actually a spinal reflex, meaning it does not involve the brain in its initial response.
The knee-jerk reflex is controlled by the interneurons in the spinal cord.
The knee-jerk reflex is a common example of a reflex. It occurs when the knee is tapped and the leg kicks out involuntarily in response.
Behaviors triggered by a reflex. Examples of this include sneezing after inhaling dust or the knee-jerk reaction when a doctor hammers your knee.

knee jerk reflex
The instrument commonly used to demonstrate the knee-jerk reflex is called a reflex hammer. It is a small, handheld device typically made of rubber and metal, designed to strike tendons gently to elicit reflex responses. The most common reflex tested is the patellar reflex, which involves the knee-jerk response when the patellar tendon is tapped.
