Mast cells are a type of white blood cell that are mainly associated with the immune system and inflammatory responses. They contain granules filled with histamine and other substances that can cause allergies and inflammation. As such, they are not involved in strengthening the skin or forming joints, which are both functions of connective tissue. They also do not play a role in insulating the body, which is the job of adipose tissue. While they can respond to certain sensations, such as pain and itchiness, mast cells themselves are not specialized to act as receptors of sensation.
