As previously stated, there are a few other structures of the integumentary system, such as hair, which is found in nearly all regions of skin. Hair also helps regulate body temperature and protect the surface of the body. An example of this is the eyelashes, which help protect the eyes. Nails are another structure, and are located on the ends of each distal phalanx – one of their functions is to protect the phalanges from trauma. The remaining structures in the integumentary system are several glands, which are present in the epidermis. These glands secrete substances that are important for many physiological functions.
