Clenching an unrelated muscle group whilst inducing a refllex causes activation of gamma motneurones which inervate intrafusal muscle fibers causing them to be more sensitive to strech. A hightened sensitivity this causes and increased reflex 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 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 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 common example of a reflex. It occurs when the knee is tapped and the leg kicks out involuntarily in response.
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.
exaggeration.
the knee-jerk reflex
knee jerk aka patellar reflex is an example of a stretch reflex
knee-jerk reflex

Reflex
Patellar reflex is an involuntary, deep tendon and myotatic 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.
The knee-jerk reflex is controlled by the interneurons in the spinal cord.
yes it is
Biceps jerk is a deep tendon reflex of the elbow to test C6 - C8 nerve roots it is an myotatic strectch reflex.
