What is withdrawal reflex quizlet?
Flexor reflex. What is the function of the withdrawal reflex? To remove a limb or other body part from a painful stimulus.
What is the flexor withdrawal reflex in infants?
Flexor withdrawal is a defensive (flight) reflex. Upon stimulation of the feet or hands of the extended limb, the infant reacts with a total flexion pattern of withdrawal. It assists in the early balancing of muscle tone between the flexors and extensors.
How does the withdrawal reflex work?
The reflex occurs when the flexors in the withdrawing limb contract and the extensors relax, while in the other limb, the opposite occurs. An example of this is when a person steps on a nail, the leg that is stepping on the nail pulls away, while the other leg takes the weight of the whole body.
Is withdrawal reflex autonomic?
One difference between a somatic reflex, such as the withdrawal reflex, and a visceral reflex, which is an autonomic reflex, is in the efferent branch. The output of a somatic reflex is the lower motor neuron in the ventral horn of the spinal cord that projects directly to a skeletal muscle to cause its contraction.

What is false about the flexor withdrawal reflex?
What is false about the flexor withdrawal reflex? Your doctor taps on your patellar tendon. List out the steps, in detail, of the nervous pathway of the reflex he is testing.
What kind of reflex is withdrawal reflex?

Specifically, the withdrawal reflex mediates the flexion of the limb that comes into contact with the noxious stimuli; it also inhibits the extensors of that same limb.
