Final answer:
The skin is the organ that receives input from the sympathetic division but not from the parasympathetic division, specifically due to the control of sweat glands by sympathetic fibers.
Step-by-step explanation:
The organ that receives major input from the sympathetic division, but not the parasympathetic division, is the skin. The sympathetic nervous system is involved in the body's "fight or flight" response and innervates the sweat glands in the skin, which are responsible for controlling body temperature and responding to stress by producing sweat. Unlike other organs that receive dual input from both autonomic subsystems, such as the bladder, salivary glands, and heart, sweat glands in the skin are an exception as they are exclusively controlled by sympathetic fibers.
The heart receives major input from the sympathetic division, but not the parasympathetic division. The sympathetic division of the autonomic nervous system prepares the body for the 'fight or flight' response, which includes increasing heart rate and blood pressure. On the other hand, the parasympathetic division controls involuntary activities during normal situations, such as digestion.
