Question

fill in the blank question

the crossed reflex is contralateral.

Explanation:

Identify the reflex type

The question asks to identify the specific reflex that is described as "crossed" and "contralateral." In neurophysiology, a contralateral reflex arc is one in which the sensory input enters on one side of the spinal cord and the motor output leaves from the opposite side.

Analyze contralateral spinal reflexes

Using the Spinal Reflexes and Reflex Arc Physiology knowledge points, we recall that the classic example of a contralateral reflex is the crossed extensor reflex. This reflex often accompanies the ipsilateral flexor (withdrawal) reflex to help maintain balance by extending the opposite limb when one limb is withdrawn from a painful stimulus.

Determine the missing term

The sentence is: "The crossed ________ reflex is contralateral."
The standard anatomical term that fits this blank is "extensor".

The crossed <blank>extensor</blank> reflex is contralateral.
