Let's discuss joints and the mechanics of the skeletal system.Pick a joint and identify the bones that are involved in thatjoint.
- The joint I picked is the ball and socket joint.
- What might be the lumps/bumps (named correctly) that areassociated with that joint to act as the surface for the joint tomove, as well as points for muscle attachment that may cause thatjoint to move?
Example: Knee joint is a hinge joint and ismade up of the femur and the tibia. The patella (a sesamoid bone)plays a role by helping with muscle movement but doesn't actuallyform part of the knee joint. The fibula is located in the same areabut doesn't form part of the knee joint. The joint surfaces are thecondyles of the femur superiorly resting on the condyles of thetibia. Both the femur and the tibia have epicondyles which are formuscle attachments that help in movement of the knee joint. Thetibia also has the tibial tuberosity which is for muscle attachmentnear the knee. The range of motion of the knee is flexion andextension.
