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.
