Skeletal System

All joints represent some type of mechanical movement such as an elbow joint is like a door hinge. Some of the other joints are hand joints, hip joints, and spine joints. I think that 
the joints are not that simple but that is a good way of representing them.
The upper part of the skull is made up of eleven parts. They are the Anterior Fontanelle, the Bregma, the Sagital Structure, the Coronal Structure, the Frontal Bone, the Lambda, the Lambdoid Structure, the Occipital Bone, Parietal Bone, the Parietal Foramen, and the Posterior Fontanelle. I am surprised there are so many parts of the upper skull.

The three bones that make up the Knee are the Femur, the Fibia, the Patella (or Kneecap). I thought there was more bones than that in a Knee.

After yesterday's class, you now know that not all joints can move! Some of the joints, like those joints in the skull, and IMMOVABLE JOINTS.

MICHAEL COLLINS SAYS:

Colby and Marek, I believe that the bones in the skull ARE movable (at least slightly), because on Thursday, at soccer tryouts, I attempted to head a very high kick (about 30 feet up), but I missed and it hit me on the top of the head. That hurt a lot, and my skull felt weird, so that's why I say that the skull bones are movable.
