Study Notes
Joint Classifications
- The joint between adjacent vertebrae, involving an intervertebral disc, is classified as amphiarthrosis.
- Joints that are classified as synarthrosis include the manubriosternal joint and cranial sutures.
- Biaxial diarthrosis joints include the metacarpophalangeal joint and hip joints.
Synovial Joints
- Synovial joints feature bones that articulate within a fluid-filled joint cavity.
- The synovial membrane secretes synovial fluid, which lubricates the joint and fills the joint cavity with a thick fluid.
Types of Joints
-
Fibrous joints:
- A syndesmosis connects the tibia and fibula.
- Gomphosis joins teeth to the jaw.
- The interosseous membrane of the forearm serves as a wide fibrous joint.
-
Cartilaginous joints:
- Symphysis occurs when bones are united by fibrocartilage, seen in adjacent vertebrae.
- Synchondrosis is present at the first sternocostal joint and in the epiphyseal plate of growing long bones.
Joint Movements
- The ball and socket joint provides the greatest range of movement.
- Hinge joints allow for uniaxial movement.
- Condyloid joints, like the radiocarpal joint, enable various movements.
- Eversion moves the bottom of the foot away from the midline.
- Circumduction describes circular movement at a condyloid joint.
- Supination refers to the motion moving the hand from a palm backward to palm forward position.
- Abduction at the shoulder joint moves the upper limb laterally away from the body.
Additional Structures
- Bursa prevents friction by cushioning between skin and bone or muscle tendon and bone.
- A meniscus is a fibrocartilage pad that provides padding between bones.
- The articulation between the articular processes of adjacent vertebrae contributes to lateral flexion of the spine.
Flexibility and Adaptability
- Fontanelles in infants are wide areas of connective tissue between cranial bones, allowing skull flexibility during birth.
