Document Summary

Synarthroses: immovable, eg. the joints of the skull. Amphiarthroses: slightly movable, only a few: eg ribs and sternum (moves when you take a breath. Diarthroses: freely movable, eg. shoulder, hip, knee, can be restricted movements. *the axial skeleton is more stable; the appendicular skeleton is more mobile. *muscles often help to stabilize joints as well as move them. Fibrous joints: fibrous material holding bones together, tight , no joint cavity, no hyaline, little to no movement. More dense irregular connective tissue usually arranged as a ligament. Eg. gomphoses: a bone fits inside a pocket bone and is attached with a ligament. Interosseus membrane -sheet of dense irregular connective tissue. Cartilaginous joints: bones are tightly connected by hyaline cartilage or fibrocartilage, still no joint cavity, might have hyaline cartilage. *without connecting hyaline > disk between two bones> fibrocartilage. Still hyaline cartilage covering surfaces (*always at locations of movement) All in midline: pubic symphysis, joints between the bodies of vertebrae.
