Loss of the knee reflex, or patellar reflex, can be caused by damage or dysfunction in the pathways involved in the reflex arc, which includes the sensory neurons, spinal cord, and motor neurons. Conditions such as neuropathy, nerve compression, spinal cord injuries, or diseases affecting the central nervous system, like multiple sclerosis or Diabetes, can impair this reflex. Additionally, certain medications or systemic conditions may also contribute to diminished reflex responses. An examination by a healthcare professional is essential for accurate diagnosis and management.
What else can I help you with?
Reflex what is the simplest reflex?
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.
Another name for the patellar reflex is the?
the knee-jerk reflex
Why is the knee jerk reflex important in walkimg?
The knee jerk reflex, or patellar reflex, is crucial for walking as it helps maintain balance and posture. When the knee is tapped, the reflex causes the quadriceps muscle to contract, stabilizing the leg and contributing to an upright position. This automatic response ensures that during walking, the body can react quickly to maintain equilibrium and prevent falls. Overall, it enhances coordination by allowing smooth, rhythmic movements of the legs.
Which ligament of the initiates the knee jerk reflex when tapped?
The patellar ligament initiates the knee jerk reflex when tapped. When the patellar tendon is tapped just below the patella, the sensory neurons detect the sudden stretch and send an impulse to the spinal cord. This reflex causes the contraction of the quadriceps muscles, resulting in the extension of the leg.
Is the knee jerk reflex an extensor thrust 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.

Another name for the patellar reflex is the?
the knee-jerk reflex
What reflex is the knee jerk reflex an example of?
knee jerk aka patellar reflex is an example of a stretch reflex
An example of a reflex?
knee-jerk reflex
Which of these is a 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 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.
Knee jerk is an example of a?
Reflex
The patellar knee jerk reflex is an example of?
Patellar reflex is an involuntary, deep tendon and myotatic reflex
Is the knee-jerk reflex a simple reflex stretch reflex or a spinal 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.
