Document Summary
Classi cations of joints: classi ed by function, synarthroses immovable joints, largely restricted to the axial skeleton, amphiarthroses slightly moveable joints, largely restricted to the axial skeleton, diarthroses freely moveable joints, predominate in the limbs, classi ed by structure, brous, cartilaginous, synovial joints. Fibrous joints: connected by brous tissue, most are immovable or only slightly movable, types: sutures, syndesmoses, gomphoses. Sutures: the bones are tightly bound by a minimal amount of brous tissue, only between bones of the skull, allow growth during childhood, during middle age bones fuse together, called synostoses, bony junctions . Syndesmoses: bones are connected exclusively by ligaments, amount of movement allowed at a syndesmosis depends on the length of the connecting bers, short little to no movement, long large amount of movement. Gomphoses: peg-in-socket joint, articulation of a tooth with its socket, periodontal ligament. Cartilaginous joints: two types, synchondroses and symphyses. Synchondroses: a joint where hyaline cartilage unites the bones, classi ed as immovable synarthroses.
