Articulation system

Fibrous joints

Sutures, Syndesmosis, Gomphosis

a fibrous joint composed of a thin layer of dense irregular connective tissue; sutures occur only between bones of the skull.

Sutures

a fibrous joint in which there is generally a greater distance between the articulating surfaces and more dense irregular connective tissue than in a suture.

Syndesmosis(interosseous membrane)

the roots of the teeth

Gomphosis

Cartilaginous

Synchondroses, Symphyses

a cartilaginous joint in which the connecting material is a solid piece of cartilage that allows little or no movement.

Synchondroses

is a cartilaginous joint in which the ends of the articulating bones are covered with hyaline cartilage, but a broad, flat disc of fibrous cartilage connects the bones. All occur in the midline of the body. The pubic symphysis between the anterior surfaces of the hip bones is one example

Symphyses

joints associated with no movements. An example is a plate that connects the epiphysis and diaphysis of a growing long bone

epiphyseal cartilage

synarthrosis

immovable

amphiarthrosis

slightly moveable

diarthrosis

freely moveable

Fluid-filled saclike extensions of the joint capsule
• Reduce friction between moving structures
• Skin rubs over bone
• Tendon rubs over bone
• Ligament rubs over bon

Bursae

Tube-like bursae that wrap around tendons at wrist and ankle where many tendons come together in a confined
space

Tendon Sheaths

Blood supplies nutrients to
all joint tissues except the

articular cartilage which is
supplied from the synovial
fluid

Degenerative joint disease
• Due to aging, wear & tear
• Non-inflammatory ---> no swelling
• Only cartilage is affected not synovial membrane
• Deterioration of cartilage produces bone spurs
• Restrict movement

Osteoarthritis

what type is the tempromandualr joint

planar/hinge

what defines the tempromandualr joint

Condylar process of the mandible &

What movements occur at the tempormandular joint

elevation and depression/recratciuon and protraction

clinical features of the tempromandualr joint

only moveable joint in the skull

GH & AC joints, many stabilizing ligaments

what type is the Elbow (Humeroulnar) Joint

hinge

what defines the Elbow (Humeroulnar) Joint

Trochlea of the humerus, the trochlear notch of the ulna, and the head of the radius

what movement occur at the elbow joint

flexion and extension

what clincical features occur at the elbow joint

Radial Annular ligament hold radius in place, collateral ligaments maintain joint
