BCR

Bulbocavernosis Reflex.  A polysynaptic reflex that can be tested to evaluate the spinal cord’s functional status (i.e., to determine if the spinal cord is in a state of shock).  It is performed by stimulating afferent, sensory fibers of the penis or clitoris (e.g., as happens when the penis or clitoris is squeezed or electrically stimulated) while observing or otherwise monitoring the anal sphincters for reflexive contraction.
