A familiar type of monosynaptic reflex that uses muscle spindle mechanoreceptors to monitor the length of skeletal muscle fibers and causes muscle contraction in response is called the…

In the micturition reflex, high volumes of urine stretch the wall of the bladder. This excites interneurons in the sacral region of the spinal cord. These interneurons cause pelvic splanchnic motor neurons to fire. The bladder contracts and pushes urine against the opening to the urethra. Check the boxes that identify the type(s) of reflex represented by the micturition  reflex. Check all that apply (i.e., there could be more than one right answer).
