General senses refer to the senses that are distributed throughout the body and allow us to feel sensations such as touch, pressure, pain, temperature, and proprioception. These senses are often thought of as "common senses" since they are experienced by most people in a similar way.
Special senses, on the other hand, refer to the senses that are dedicated to specific functions such as sight, hearing, taste, smell, and balance. These senses are highly specialized and require specific receptors in order to function.
In summary, general senses refer to the senses that are distributed throughout the body and provide us with a general sense of our environment, while special senses refer to the highly specialized senses that provide us with specific information about our environment.
