A 49-year-old man is brought to the physician for a routine examination. He sustained a complete spinal cord transection at the T10 level during a motor vehicle collision 2 months ago. A foley catheter has been inserted, and he also requires garment protection for fecal incontinence. He is now confined to a wheelchair. He asks, "Will I ever be able to regain control of my own urination?" The physician recommends tickling or scratching the genital region to produce voiding. This approach is most likely to be effective because of which of the following characteristics of the micturition reflex? a. afferent signals for micturition

a. afferent signals for micturition are transmitted via sacral parasympathetic nerves
b. cerebral cortical centers are required for micturition to occur
c. efferent signals for micturition are transmitted via the pudendal nerve
d. micturition is an autonomous local spinal cord reflex
