Is the Patellar reflex inhibited or enhanced by voluntary muscle activity in the quadriceps?
The patellar reflex is inhibited
Where are the muscle spindles of the patellar reflex located?
they are located in knees.
Stimulation of the patellar tendon results in a muscle contractions called what?
A reflex.
Where are sensory stretch receptors of the withdrawal reflex located?
they are located in the limbs, because the limbs are the effectors of the withdrawal reflex.
How does the stretch reflex cause the quadriceps femoris muscle group to contract?
Tapping on the patellar tendon stretches receptors called the muscle spindles in the quadriceps muscle group of the anterior thigh. This stimulus evokes a rapid motor reflex to contract the quadriceps and shorten the muscles. This process is called the patellar reflex.
The patellar knee jerk reflex is an example of?
Patellar reflex is an involuntary, deep tendon and myotatic reflex
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.
What does the patellar reflex employ?
A sharp tap just below the knee.
Is the patellar reflex more or less vigorous after exercise?
The patellar reflex is more vigorous after exercise.
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.
What type of reflex does not involve the brain?
A spinal reflex does not involve the brain. This type of reflex is controlled by the spinal cord and does not require the brain to initiate a response. Examples include the knee-jerk reflex and the withdrawal reflex.
Is a patellar reflex autonomic?
no
