or (synchondorsis) cartilage -2 bones with tissue btw 2 -no flexion or extension -pretty immobile (for ex. Sutures of skull have some mobility when you’re young but it’s not good-syndosmoses) Ex: gomphosis-when dentist takes out teeth (syndosmoses) |
|
Discontinuous aka synovial joints (diarthrosis)
|

|
