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 a common example of a reflex. It occurs when the knee is tapped and the leg kicks out involuntarily in response.
The patellar reflex is a type of stretch reflex that involves tapping the patellar tendon to elicit a contraction of the quadriceps muscle and extension of the knee. This reflex helps to maintain balance and stability.
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.
The knee reflex is also called the knee-jerk reflex by tapping the patellar tendon with a reflex hammer. This sends sensory information to the spinal cord at L4 and motor information back to the Quadriceps in the thigh (relaxing the hamstrings). This is reflex requires only two neurons. No interneuron. And so is very rapid. It is important in balance and posture.
the knee-jerk reflex
The efferent organ for the knee-jerk reflex is the quadriceps muscle in the thigh. When the patellar tendon is tapped, sensory neurons send a signal to the spinal cord, which then activates motor neurons that innervate the quadriceps. This results in the contraction of the quadriceps muscle and the characteristic kicking motion of the leg.

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.
