Solutions
gliding joint usually between two flat surfaces & allows the least movement of all
synovial joints, only small shifting movements are possible at these articulations
carpal bones & tarsal bones examples of gliding joints
ellipsoid joint consists of oval-shaped end of one bone articulating with the elliptical basin
of another bone, it permits flexion/extension & abduction/adduction
wrist (radiocarpal) example of an ellipsoid joint
saddle joint modified ellipsoid joint composed of convex & concave articulating surfaces
- like 2 saddles
located between trapezium (one of the small carpal bones in the wrist & the first metacarpal bone
example of a saddle joint
pivot joint designed to allow one bone to rotate around the surface of another bone

Solutions
located between C1 & C2 (atlantoaxial joint) example of a pivot joint
agonist a muscle that carries out an action
antagonist a muscle that has an opposite action of the agonist
synergist a muscle that supports the agonist
skeletal muscle voluntary contractile tissue that moves the skeleton
tendons attached muscle to bone
ligaments connect bones together at a joint
