functional junctions between bones.
dense connective tissue; many collagenous fibers; bones are close together; 3 types
Fibrous joints; bones are bound by long fibers of connective tissue that form an interosseous ligament.
permit slight movement
only between bones of the skull; sutural ligament
thin layer of dense connective tissue
formed by union of cone-shaped bony process in a bony socket. periodontal ligament
surrounds the root and firmly attaches to the jaw with thick bundles of collagenous fibers
hyaline cartilage or fibrocartilage; two types
bands of hyaline cartilage unite bones; many are temporary structures; manubrium and first rib
limited amount of movement; articular surfaces are covered by thin layer of hyaline cartilage and this cartilage is attached to fibrocartilage.
more complex structurally; consist of articular cartilage, joint capsule, and synovial membrane
secrete synovial fluid; inner layer of a joint capsule; consists of a shiny, vascular lining of loose CT; few cells thick
tubular; two distinct layers, holds together the bones of synovial joint. outer layer-dense CT
bundles of strong, touch collagenous fibers; reinforce joint capsules
fibrocartilage, located between articular surfaces. ex: knee-crescent shaped
fluid filled sacs, has inner lining of synovial membrane. contian synovial fluid. between skin and bony prominences
ball and socket joint
bones with globular or egg-shaped head that articulates with cup shaped cavity.
ovoid condyle of one bone fits into the elliptical cavity of another bones. variety of movements, no rotation
nearly flat or slightly curved, sliding or twisting
convex surface of one bone fits into concave surface surface of another; flexion and extenstion
cylindrical surface of one bone articulates with ring of bone and fibrous tissue; rotation around central axis
both concave and convex regions, one bone is complementary surface to the other; variety of movements in two planes
bending parts at a joint so that the angle between them decreases and parts come closer together
straightening parts of a joint so the angle between them increases and parts move farther apart
bending foot upward
bending the foot downward
moving part away from mid line
bending head back beyond the upright position
moving a part toward the mid line
moving a part around an axis
moving a part so that its end follows a circular path
turning the hand so the palm is upward; anterior
turning the hand so the palm is downward
turning the foot so the sole faces laterally
turning the foot so the sole faces medially
moving a part forward
moving a part backward
raising a part
lowering a part
Synovial jt. ball and socket joint that consists of the rounded head of the humerus and glenoid cavity of scapula
composed of broad band of CT that connects coracoid process to greater tubercle of humerus.
three bands of fibers that appear as thickenings in the ventral wall of the joint capsule.
Transverse Humeral ligament
consists of a narrow sheet of CT fibers that runs between the lesser and greater tubercles of the humerus
composed of fibrocartilage, attached to margin of glenoid cavity and forms a rim.
complex structure, includes two articulations (hinge joint and gliding joint)
Ulnar collateral ligament
thick band of Dense CT, located in the medial wall of the capsule.
Radial collateral ligament
strengthens the lateral wall of the joint capsule, fibrous band
ball and socket joint that consists of the head of femur and acetabulum of the coxa.
consits of Y-shaped band of very strong fibers that connect the anterior inferior iliac spine of the coxa to the intertrochanteric line of the femur. strongest ligament of the body
extends between the superior portion of pubis and the iliofemoral ligament. fibers blend with the fibers of the joint capsule
consists of a band of strong fibers that originates on the ischium posterior to acetabulum, blends with fibers of joint capsule
largest and most complex of synovial joints
continuation of a tendon from a large muscle group in the thigh. strong, flat band that extends from patella to tibial tuberosity
oblique popliteal ligament
connects the lateral condyle of femur to margin of the head of the tibia.
Arcuate popliteal ligament
appears Y-shaped system of fibers that extends from lateral condyle of femur to head of fibula.
Tibial collateral ligament
broad, flat band of tissue that connects medial condyle of femur to medial condyle of tibia
Fibular collateral ligament
consist of a strong, round cord located between the lateral condyle of the femur and head of fibula
(fibular collateral ligament) help prevent displacement of the articulating surfaces
