bones that form in soft tissues where they are not normally present ( riders)
What are the types of synovial joints?
1. pivot - uniaxial atlantoaxial joint
2. ball and socket - multiaxial joint,femur
3. plane - uniaxial, acromioclavicular joint
4. hinge -uniaxial, elbow joint
5. saddle - biaxial, thumb, TMJ
6. condyloid - biaxial; metacarpophalangeal
what are fibrous joints and give examples
joined by fibrous tissue such as sutures
-syndesmosis type: partially movable as in the interosseous membrane between the radius and ulna
-gomphosis: between the root of the tooth and the alveolar process of the jaw
what are cartilaginous joints?
united by hyaline cartilage or fibrocartilage. 2 types:
1. Primary: allow slight bending during early life, (epiphysial plate during bone development)
2. Secondary: united by fibrocartilage (intervertebral disc)

What is compartment syndrome?
Increased pressure within one or more fascial compartments so that vascular perfusion is compromised.
