![]() As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a robust but flexible type of connective tissue. ![]() (a) Sutures (b) Syndesmosis (c) Gomphosis.Īt a cartilaginous joint, the bones are joined by hyaline cartilage or fibrocartilage. Gomphoses occur between teeth and their sockets the term refers to the way the tooth fits into the socket like a peg.įibrous joints: Image demonstrating the three types of fibrous joints. Syndesmoses-joints in which the bones are connected by a band of connective tissue, allowing for more movement than in a suture. Sutures are found only in the skull and possess short fibers of connective tissue that hold the skull bones tightly in place. Sutures, syndesmoses, and gomphoses are the three type of fibrous joints. These fixed or immovable joints are typically interlocked with irregular edges. The structural joints include fibrous, cartilaginous, and synovial, each of which has its subgroups.įibrous joints are connected by dense, tough connective tissue that is rich in collagen fibers. They can be classified based on structure and function. These are flat bone, sutural bone, short bone, irregular, sesamoid bone, and long bone.Ī joint is a connection that occurs between bones in the skeletal system. The patellae (singular = patella) are the only sesamoid bones found in common with every person.īone types: This image shows the different bone classifications, based on shape, that are found in a human skeleton. Sesamoid bones vary in number and placement from person to person but are typically found in tendons associated with the feet, hands, and knees. The sesamoid bones protect tendons by helping them overcome compressive forces. ![]() These bones form in tendons, where a great deal of pressure is generated in a joint. A sesamoid bone is a small, round bone that, as the name suggests, is shaped like a sesame seed. Flat bones serve as points of attachment for muscles and often protect internal organs. Examples include the skull bones, the shoulder blades bone, the breastbone, and the ribs. They provide stability and support as well as some limited motion.įlat bones are typically thin and often curved. The only short bones in the human skeleton are in the carpals of the wrists and the tarsals of the ankles. A short bone is one that is cube-like in shape, being approximately equal in length, width, and thickness. They are found in the arms and legs, as well as in the fingers and toes where they function as levers they move when muscles contract. A long bone is cylindrical one, being longer than it is wide. The skeletal structure consists of different types of bone, joints, and significant skeleton designs that support, protect, and provide movement to the bodies.Ī skeletal system is made of 4 types of bones these are long, short, flat, sesamoid, and irregular bones.
