What are False joints?
continuous bone connections in which the intervening tissue consists of fibrous connective tissue, cartilage, or bone
3 examples of Synarthroses (false joints)
- Syndesmoses (fibrous joints)
- Synchondroses (cartilaginous joints)
- Synostoses (sites of bony fusion)
What are true joints?
discontinuous connections in which the bones are separated by a joint space
2 types of true joints
- Diarthroses
- Amphiarthroses
What is Amphiarthroses?
“Stiff joints” whose mobility is greatly limited by strong ligaments (e.g., the sacroiliac joint and proximal tibiofibular joint)
How are Diarthroses classified?
according to various criteria:
- Shape and arrangement of the articular surfaces
- Number of joint axes
- Number of degrees of freedom
Name these joints.
What is the joint type?
a Interosseous membrane.
b Tibiofibular syndesmosis.
c Fontanelles.
→ Syndesmoses (fibrous joints)
What is gomphosis?
a fibrous joint.
→ The roots of the teeth (the pegs) fit into their sockets in the mandible and maxilla and are the only examples of this type of joint.
Name this joint
→ Joint type?
Sacrum (fused sacral vertebrae).
→ Synostoses (sites of bony fusion)
Name of this joint.
→ Joint type?
Hip bone(fusion of theilium, ischium, and pubis). → Synostoses (sites of bony fusion)
What does translation mean in anatomy?
a body is sliding on a straight or curved path without rotating.
→ As a result, all points on the moving body travel an equal distance in the same direction.
What type of joint is this?
→ How many axes and movements does it have?
Spheroidal joint
→ 3 axes of movements → 6 primary movements
(e.g, hip joint)
What type of joint is this?
→ How many axes and movements does it have?
Hinge joint
→ 1 axis of movement
→ two primary movements (example: parts of the elbow joint).
What type of joint is this?
→ How many axes and movements does it have?
Ellipsoid joint
This joint is biaxial and has four primary movements (example: the radiocarpal joint).
What type of joint is this?
→ How many axes and movements does it have?
This is a biaxial joint with four primary movements (example: the carpometacarpal joint of the thumb).
What type of joint is this?
→ How many axes and movements does it have?
Pivot joint
→ a uniaxial joint with two primary movements (example: the proximal radioulnar joint).
What type of joint is this?
→ How many axes and movements does it have?
The only movement allowed is a translation (sliding) of one member on the other (example: vertebral facet joint).
