What reflex is the knee jerk reflex an example of?
knee jerk aka patellar reflex is an example of a stretch reflex
Another name for the patellar reflex is the?
the knee-jerk reflex
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 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
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.
An example of a reflex?
knee-jerk reflex
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.
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.
Knee jerk is an example of a?
Reflex
what type of reflex is the knee?
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.
