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 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-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 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.
yes, the knee relfex felt when tapped just below the knee cap on the patellar tendon is a somatic reflex which is a contraction of skeletal muscles. the opposite would be autonomic relfexes which consist of contractions of smooth or cardiac muscle or secretion by glands.

A spinal reflex does not involve the brain. This type of reflex is controlled by the spinal cord and does not require the brain to initiate a response. Examples include the knee-jerk reflex and the withdrawal reflex.

knee-jerk reflex
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 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 simplest reflex is a monosynaptic reflex, which involves only two neurons: a sensory neuron and a motor neuron. An example of this is the knee-jerk reflex, where tapping the knee causes a quick, automatic extension of the leg.
Reflex
Patellar reflex is an involuntary, deep tendon and myotatic reflex
No, the knee jerk reflex is a monosynaptic reflex that involves the contraction of the quadriceps muscle to extend the knee in response to a tap on the patellar tendon. It is not considered an extensor thrust reflex, which involves a more complex pattern of muscle activation to generate forceful extension of the limb.
