Where does crossed extensor reflex occur?

Where does crossed extensor reflex occur?

Crossed Extensor Reflex 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.

In which Reflex does a contralateral extensor muscle contract?

Crossed-Extensor Reflex In this case, the ipsilateral limb reacts with a withdrawal reflex (stimulating flexor muscles and inhibiting extensor muscles on same side), but the contralateral extensor muscles contract so that the person can appropriately shift balance to the opposite foot during the reflex.

Is the crossed extensor reflex somatic or autonomic?

somatic reflex – Any reflex (relatively rapid and predictable motor response to a stimulus) in which the effectors are skeletal muscles, e.g., the patellar reflex, the flexor or withdrawal reflex, the crossed extensor reflex, the plantar reflex, the abdominal reflexes, etc.; most named somatic reflexes are inborn/ …

How is the crossed extensor reflex tied in with the withdrawal reflex?

The crossed extensor reflex is just a withdrawal reflex on one side with the addition of inhibitory pathways needed to maintain balance and coordination. For example, you step on a nail with your right foot as you are walking along. This will initiate a withdrawal of your right leg.

What causes lack of reflexes in legs?

If your doctor rates your reactions 0 or 1, your muscles show little to no contraction during the test. The most common cause of low reflex response is peripheral neuropathy. Diabetes, anemia, and vitamin deficiency are possible causes of absent reflexes.

Why does my leg kick when the doctor hits it?

The most familiar reflex is the knee jerk, when a doctor taps on the tendon below your knee with a reflex hammer and that leg kicks out. The stimulus (the hammer) results in a signal being sent via a sensory nerve to the spinal cord.
