How does integumentary and nervous system work together?

Is your nail attached to your skin?
Fingernails and toenails are made from skin cells. Structures that are made from skin cells are called skin appendages. The nail is firmly attached to the nail bed beneath it. The nail and nail bed separate at the tip of the finger or toe, where the end of the nail sticks out.
Are nails bones or skin?

What role does your skin play in the regulation of body temperature?
The skin’s immense blood supply helps regulate temperature: dilated vessels allow for heat loss, while constricted vessels retain heat. The skin regulates body temperature with its blood supply. The skin assists in homeostasis. Humidity affects thermoregulation by limiting sweat evaporation and thus heat loss.
Why does my skin stick to my nail?

What are two functions of the nail?
Function. A healthy fingernail has the function of protecting the distal phalanx, the fingertip, and the surrounding soft tissues from injuries. It also serves to enhance precise delicate movements of the distal digits through counter-pressure exerted on the pulp of the finger.
How do body systems work together?
Just as the organs in an organ system work together to accomplish their task, so the different organ systems also cooperate to keep the body running. For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce.
