Endoskeletons are the internal skeleton of an animal. These are found in vertebrates that have bones and cartilages. They are exactly located within the soft tissues of vertebrates that provide support, protect internal organs, and allow movement through muscle contractions that are attached to the skeletons.
Humans have an endoskeleton that consists of 206 bones in the adult body. Aside from providing support and structure to the body, the endoskeleton also stores minerals and lipids, and helps in the production of blood cells in the body.
