In the lateral horns of the thoracic and upper segments of the lumbar spinal cord are the spinal centers of the sympathetic nervous system that innervate the heart, blood vessels, sweat glands, digestive tract, skeletal muscles, i.e. all organs and tissues of the body. Parasympathetic centers that innervate the pelvic organs (reflex centers of urination, defecation, erection, ejaculation) are located in the sacral spinal cord.
