Types of joints

1
Types of joints

• (joints are also called articulations)

2
Synovial Joints

• Freely moveable joints
• Cavity at the joint
• Encapsulated by dense connective tissue
• The dCT secretes synovial fluid
• The epiphysis of the bones is covered with
  cartilage
• Have tendons and ligaments around them

3
Types of synovial joints

• Gliding joints, found intercarpal and
  intertarsal the articulating surfaces are
  typically flat
• Hinge joints, found in the fingers and elbow the
  spoon-like surface fits into a concave surface
  (F/E)
• Pivot joints, found at the atlas and axis as
  wellas between the proximal ends of the radius
  and ulna surface fits into a ring formed by bone
  and ligament (Rot)

4
Types of synovial joints, continued

• Ellipsoidal, between radius and carpals oval
  into an elipse (F/E, Ab/Ad, Circ)
• Saddle, where the thumb attached to the wrist
  like a saddle and a rider (F/E, Ab/Ad, Circ)
• Ball and socket, shoulder joint where a ball
  fits into a cuplike depression (F/E, Ab/Ad, rot,
  circ)

5
Cartilaginous joints

• Cartilage fill the space between the joints,
  allowing only a little motion
• Between vertebrae
• Between sternum and ribs

6
Fibrous joints

• Fibrous connective tissue joins the bones
  (fontanelles)
• No real space between bones
• Allows bones of skull to cross during childbirth
