Which statement represents the correct order of the reflex arc for micturition?
A.

B. The reflex arc begins with stretch receptors in the urinary bladder's walls - stretch receptors send signals to the sacral region of the spinal cord - the detrusor muscle contracts the internal urethral sphincter relaxes - parasympathetic neurons go from the spinal cord to the detrusor muscle - urine is passed. C. The reflex arc begins with stretch receptors in the urinary bladder's walls - stretch receptors send signals to the sacral region of the spinal cord - parasympathetic neurons go from the spinal cord to the detrusor muscle - the detrusor muscle contracts the internal urethral sphincter relaxes - urine is passed. D. The reflex arc begins with stretch receptors sending signals to the sacral region of the spinal cord - stretch receptors receive signals in the urinary bladder's walls - the detrusor muscle contracts the internal urethral sphincter relaxes - parasympathetic neurons go from the spinal cord to the detrusor muscle - urine is passed.
