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 best examples of this is to shin a light in one eye and both pupils constrict. You are testing cranial nerve II.Or the corneal reflex (touch one cornea) both eyes blink, a test of CN VII or the palpebral reflex, touch one eye lid or lashes and both eyes blink, another test of CN VII.
You probably mean the pupillary reflex. It is the reflex responsible for your pupils constricting (becoming smaller) when exposed to light and dilating (becoming bigger) when you walk into a dark room.
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 reflex that causes an infant to close its fist when the palm is touched is called the grasp reflex.
Reflex hammer.
The modern reflex hammer is referred to as a Tomahawk or Taylor reflex hammer and was designed by John Taylor in 1888. That is the most well known one in the US. There is also the Babinski reflex hammer and it was developed in 1912 by Joseph Babinski and it is often seen in neurological settings.
The instrument used by a doctor to test knee reflex is a reflex hammer. The doctor will tap the patellar tendon just below the kneecap with the reflex hammer to elicit a reflex response, which helps assess the function of the nerves and spinal cord.
The proper name for the hammer a doctor uses to test your reflex is just "reflex hammer". It is a medical instrument used by physicians to test deep tendon reflexes and is an important part of a neurological physical examination.

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 most well-known human reflex is the knee-jerk (or patella) reflex. This is the one where you use a reflex hammer to hit the tendon just below the kneecap (or patella). The leg jerks out like you're kicking.
DTR testing or deep tendon reflex testing uses a reflex hammer to strike the tendon in an extremity checking for a response or the absence of a response when the muscle is stimulated by the hammer.
You can purchase a slide hammer a ACE
It is a tomahawk-shaped rubber instrument used to test reflexes in order to determine if an individual's nerve reflexes are functioning properly. There is no specialized name for this instrument, though it is commonly referred to as a mallet.
A reflex hammer is used by healthcare professionals to test a patient's reflexes. By tapping specific areas of the body, such as the knee or elbow, with a reflex hammer, they can assess the integrity of the nervous system and identify any abnormalities or underlying conditions. It is an important tool in diagnosing neurological disorders and monitoring patients' health.
