skeleton Flashcards
bones, joints and ligaments
ligament
connects bones to bones at joints
composed of connective tissue with largely parallel arrays of collagen fibres or (less frequently) another fibrillar protein called elastin
tendon
connects muscle and bone
composed of connected tissue comprised of parallel bundles of collagen fibres
flattened out as aponeurosis
fibrous joints
adjacent articulating bones bound together by fibrous (collagen-containing) connective tissue. provide stability but little movement.
suture
fibrous joint present between flat bones
e.g. between bones of the cranium in skull
syndemosis
fibrous joint between long bones
e.g. joint between lower end of tibia and fibula, just above the ankle
cartilaginous joint
articulating bones held together by cartilage
primary cartilaginous (synchondrosis) joints
consist of hyaline cartilage. found between developing and maturing bone
in adults, link ribs to costal cartilages
secondary cartilaginous (symphysis) joints
surfaces of the articulating bones are lined by hyaline cartilage with a fibrocartilage disc/pad in between
permit a limited amount of movement
all lie on the midline of the body
e.g. intervertebral discs, manubriosternal joint between the manubrium and body of the sternum, symphysis pubis between two pubic bones
synovial joint
joint with cavity containing a small volume of synovial fluid
articulating surfaces of the bones covered with smooth, articular hyaline cartilage and lubricated by the synovial fluid (ensuring minimal friction)
joint enclosed by fibrous capsule, lined on its inner surface by a synovial membrane
