The Femoral nerve.
Wikipedia:
Striking the patellar tendon with a tendon hammer just below the patella stretches the quadriceps muscles in the thigh. This stimulates stretch sensory receptors (i.e. muscle spindles) to trigger an afferent impulse in a sensory Ia-nerve fiber of the femoral nerve which synapses (without interneurones) at the level of L4 in the spinal cord, completely independent of higher centres.

What is tested in patella reflex?
The patella reflex tests the integrity of the patellar tendon and the sensory and motor pathways that control the reflex. When the patellar tendon is tapped, it should cause the quadriceps muscle to contract and the lower leg to extend. If there is a lack of response or an abnormal response, it can indicate a problem with the nervous system.
Is the patellar reflex more or less vigorous after exercise?
The patellar reflex is more vigorous after exercise.
Another name for the patellar reflex is the?
the knee-jerk reflex
What is a normal reaction for the patellar reflex?
knee jerk
What is the effector involved the patellar reflex?
In order to provoke the patellar reflex one must strike the patellar tendon with a tendon hammer (and only a tendon hammer, striking with an ordinary hammer is ill-advised). In other words, strike the region immediately below the patella.
The patellar knee jerk reflex is an example of?
Patellar reflex is an involuntary, deep tendon and myotatic reflex
What is tested in patella reflex?

What nerve is tested in a biceps reflex test?
musculocutaneous nervethe musculocutaneous nerve
Is the Patellar reflex inhibited or enhanced by voluntary muscle activity in the quadriceps?
The patellar reflex is inhibited
Is the patellar reflex more or less vigorous after exercise?
The patellar reflex is more vigorous after exercise.
What type of reflex does not involve the brain?
Patellar Reflex.
The patellar reflex is a type of?
knee jerk aka patellar reflex is an example of a stretch reflex
Is a patellar reflex autonomic?
no
Another name for the patellar reflex is the?
the knee-jerk reflex
What nerve is carrying the afferent and efferent impulses during the patellar reflex?
The nerves innervate the quadriceps. The afferent nerves are the muscle spindles and the efferent are the motor neurons.
What reflex is the knee jerk reflex an example of?
knee jerk aka patellar reflex is an example of a stretch reflex
Which ligament of the knee initiates the knee-jerk reflex?
The patellar tendon, just underneath the kneecap
