Articular System

Carpals and tarsals (flat bones) are examples of this type of joint

• condyloid

• gliding

• hinge

• saddle

Synovial or Diarthrodial Joint?

• Thin layer of fibrous periosteum between the 2 bones

• Disc connect vertebrae

• No direct contact between 2 bones.

  Joint space or cavity.

Syndesmosis?

• “Bolted” together

• Ends of the bones interlock

• Held together with fibrous tissue, ligaments.

  Small amount of movement.

Function of a joint?

• Allow motion, Bear weight, Provide Stability

• Strong

• Heavy

• Hard and dense type of bone

-Synovial is lined with a joint capsule.

•Outer capsule strong fibrous material.

•Inner layer lined with ___________________.

-Synovial fluid

•Lies within cavity/capsule.

•Fluid is secreted by __________________

Synovial fluid: thick clear fluid that lubricates the articular cartilage and joint. What else?

• Reduces friction

• Provide shock absorption

• Source of nutrition for joint

3 types of cartilage

• Hyaline or Articular Cartilage

• Fibrocartilage

• Elastic Cartilage

Hyaline /articular cartilage

• Cover ends of opposing bones

• Shock absorber

• Pad structure

• Strong

Which type of joint is primarily responsible for allowing rotational movement?

• Ball and socket

• Hinge

• Pivot

• Saddle
