- 1In this type of joint, classified by structure, bones held by dense connective tissue. there's less motionfibrous joint
- 2three examples of fibrous jointsgomphosis, suture, syndesmosis (interosseous membrane between joints)
- 3In this type of joint, classified by structure, bones are joined by cartilage. There's a little more motion.Cartilaginous joint
- 4examples of cartilaginous jointsSynchondrosis (in growth of child at epiphyseal plate and costochondral joints)
Symphysis (contains fibrocartilage - pubic symphysis and intervertebral joint) - 5Must have articular capsule with outer fibrous and inner synovial layer, synovial fluid, articular cartilage on the end of bones which is nourished by chondrocytes and acts as a shock absorber and is avascular. Ligaments are here.synovial joint
- 6something that rotates around a fixed point. Effort in one spot, resistance at another. Movement occurs if effort exceeds resistance.lever
- 7IMA is greater than your EMA (greater than 1 when you divide them) for mechanical advantage1st class lever
- 8lever always has mechanical advantage always greater than 12nd class
- 9less than 1 - IMA is always less than EMA. That’s a mechanical disadvantage.3rd class
