Question

A technician is drawing blood from your arm for blood tests. As you feel the pain of the needle, you suppress your flexor reflex. Name the ascending pathway that carries pain signals and the region of the cortex that receives
them (use Figure). Next, name the descending pathway you would use to inhibit the flexor reflex (use Figure).
