Special senses are known for having:

The correct answer highlights that special senses, such as vision, hearing, taste, smell, and balance, are characterized by anatomically distinct structures. Each of these senses has specific organs that are uniquely adapted to detect certain types of stimuli. For instance, the eyes are specialized for detecting light and forming images, the ears are designed for detecting sound waves and maintaining balance, the nose has olfactory receptors for smell, and the tongue contains taste buds for taste sensations.

This anatomical distinction is vital for the functioning of each sense; it allows the body to process sensory information accurately and efficiently. Each sensory organ is equipped with a specialized structure and cellular arrangement that enhances its ability to interact with environmental stimuli, improving the organism's ability to perceive and respond to the world around it.

The other options relate to aspects that do not accurately represent the unique nature of the special senses. For example, while some sensory receptors are dispersed in various tissues (as seen with touch and pain), special senses are defined by their concentration in distinct, specialized organs. Thus, the distinction in anatomy is a fundamental characteristic of the special senses.
