Is the Patellar reflex inhibited or enhanced by voluntary muscle activity in the quadriceps?

The patellar reflex is enhanced by voluntary muscle activity in the quadriceps. When you contract your quadriceps, it stretches the patellar tendon, causing a stronger reflex response when the knee is tapped.


The patellar reflex is a type of?

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.


Which of the following is not correct regarding the patellar knee jerk 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.


What is patellar knee-jerk reflex a somatic or autonomic reflex?

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.


What kind of reflex uses just two neurons?

The patellar reflex, commonly known as the knee-jerk reflex, uses just two neurons. When the patellar tendon is tapped, a signal is sent along a sensory neuron to the spinal cord, which synapses with a motor neuron to trigger the contraction of the quadriceps muscle and extend the leg.

Why does not the patellar reflex happen when your leg is straight?

When the leg is straight, the muscle spindle receptors in the quadriceps muscle are not stretched enough to stimulate a reflex response. The reflex occurs when the muscle is quickly lengthened, activating the sensory receptors in the muscle and sending a signal to the spinal cord to trigger a reflexive contraction of the quadriceps muscle.


Is a patellar reflex autonomic?

no

It may modify it.
