origin
where muscle attaches
usually proximal
insertion
where other end of muscle attaches
usually distal

helps agonist move
usually on same side of appendage
6 types of joints
ball and socket

saddle
pivot
gliding
condyloid
synarthrotic
immovable joint
amphiarthrotic
semi-moveable joint

movable joint
synchondrosis
with cartilege
synostosis
with bone
synarthrosis
with joint
syndesmosis
with fibrous connective tissue
synovial
with egg like (has a sac with synovial fluid in it)
symphysis
with growth together
gomphoses
-found in mandible
-where root of tooth is attached to alveoli
-synarthrotic fibrous joint
sutures
-found in skull
-synarthrotic fibrous joint
tibiofibularis
-between distal ends of tibia/fibula
- syndesmosis amphiarthrotic joint
radiounlaris
-between distal ends of radius/ulna
-syndesmosis amphiarthotic joint
