1. Which bone (yellow) is centrally located and joins with most of the other bones of the skull? The link of the video at the study guide.

• The yellow-colored bone in the video is the sphenoid bone.

2.  What are the two mechanisms by which the bones of the body are formed and which bones are formed by each mechanism?

•  As stated in the video, there are two types of bone formation, the intramembranous ossification and endochondral ossification. Ossification forms the skeleton, as it lengthens and thickens bone.  Intramembranous ossification forms spongy bone, red bone marrow, compact bone, as well as the skull bone. On the other hand, endochondral ossification is responsible for the replacement of cartilage with bone. It produces long bones, vertebrae, and ribs. 

3.  What are the synovial joints being described in the video?

• The synovial joints discussed in the video presentation are the following:

1. ball-and-socket joint

2. hinge joint

3. pivot joint

4. condyloid joint

5. saddle joint 

6. gliding joint 

   4. Which type of synovial joint allows for the widest ranges of motion?

• Ball and socket joints are the joints that allow the widest range of motion, which are usually found in the hip and shoulders.
