Joint
Also known as articulation
Joint
Scientific study of joints
Arthrology
Study of motion of the human body
Kinesiology
A joint’s ______determines its combination of strength and flexibility
Structure
Structural classification of joints
- fibrous joints
- cartilaginous joints
- synovial joints
- types of movement
- type of synovial joint
Functional classification of joints
- Synarthrosis
- Amphiarthrosis
- diarthrosis
______ classification of joints relates to the degree of movement they permit
Functional
An immovable joint
Synarthrosis
A slightly immovable joint
Amphiarthrosis
A freely movable joint
Diarthrosis
Structural classification of joints is based on two criteria:
- Presence or absence of space between articulating bones (synovial cavity)
- type of connective tissue holding the bones together
No synovial cavity and bones are held together by dense irregular connective tissue
Fibrous joint
No synovial cavity and the bones are held together by cartilage
Cartilaginous joints
United by the dense irregular connective tissue of an articular capsule, and often by ligaments
Synovial joints
____ permit little or no movement.
Fibrous joints
The three types of fibrous joints are
(1) syndesmoses
(2) sutures
(3) interosseous membranes
joint permits limited movement
(distal tibia and fibula) and gomphosis (dentoalveolar joint)
Syndesmosis
– fibrous joint that may be a slightly movable or immovable (found between skull bones)
Suture
