Study Notes

Classification of Joints

Joints are classified structurally into bony, fibrous, cartilaginous, and synovial types.
Synarthrosis is an immovable joint.
Diarthrosis represents a freely movable joint, typically synovial.

Types of Synarthrotic Joints

Gomphosis connects teeth to bony sockets.
Sutures are immovable joints found in the skull.
Synchondrosis, like the rib-sternum connection, allows limited movement.
Synostosis occurs when bones fuse together.

Movement Classifications

Amphiarthrosis denotes slightly movable joints.
Hinge joints, like the ankle, allow flexion and extension.
Lateral movements such as abduction move limbs away from the midline of the body.

Joint Characteristics

Strong joints are tightly fitted with limited movement.
Articular cartilage surfaces are slick and smooth for reduced friction.
Synovial fluid lubricates joints, but does not increase osmotic pressure.
Bursae provide cushioning in joints, absent around blood vessels.

Joint Injury and Health

Damage to articular cartilage leads to rough surfaces and increased friction.
Sprained ligaments, like in an ankle injury, result from stretching and collagen damage.
Degenerative changes can occur in joints due to various factors, excluding bursitis.

Movement Definitions

Pronation involves rotation of the radius over the ulna.
Opposition describes pinching movements between the thumb and other fingers.
Inversion refers to ankle movement turning the sole inward, while eversion is the opposite.

Joint Types

Condylar joints connect fingers to metacarpals and wrist bones.
Saddle joints, like between the trapezium and thumb metacarpal, allow multidirectional movement.
Monaxial joints are classified further but specifics on movement types remain incomplete.
