What else can I help you with?
Another name for the patellar reflex is the?
the knee-jerk reflex
Describe how the patellar knee-jerk reflex operates?
The patellar knee-jerk reflex is a monosynaptic reflex arc involving the sensory neurons, spinal cord, and motor neurons. When the patellar tendon is tapped, sensory receptors called muscle spindles detect the stretch and send a signal to the spinal cord. The spinal cord then immediately sends a signal back to the quadriceps muscles to contract, causing the knee to jerk involuntarily.
What is ankle jerk?
The ankle jerk, also known as the Achilles reflex, is a deep tendon reflex that occurs when the Achilles tendon is tapped, usually at the back of the ankle. This action causes the calf muscles to contract and the foot to jerk downward. It is often tested during neurological examinations to assess the integrity of the S1 and S2 spinal nerves. A diminished or absent ankle jerk can indicate potential neurological or muscular issues.
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.
What is a normal reaction for the patellar reflex?
knee jerk
Which ligament of the knee initiates the knee-jerk reflex?
The patellar tendon, just underneath the kneecap
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.
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
The process tapping the knee and resulting reaction is called a?
The process is called a knee jerk reflex. It is a simple reflex that occurs when the patellar tendon is tapped, resulting in the lower leg kicking forward involuntarily.
What movement would you expect to occur during the Achilles reflex?
During the Achilles reflex test, you would expect to see plantar flexion of the foot, where the foot points downwards, in response to tapping the Achilles tendon. This reflex is a protective mechanism that helps maintain posture and balance in the lower extremities.

An example of a reflex?
knee-jerk reflex
What is the efferent organ for the knee-jerk reflex?
The efferent organ for the knee-jerk reflex is the quadriceps muscle in the thigh. When the patellar tendon is tapped, sensory neurons send a signal to the spinal cord, which then activates motor neurons that innervate the quadriceps. This results in the contraction of the quadriceps muscle and the characteristic kicking motion of the leg.

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.
