Which bone (yellow) is centrally located and joins with most of the other bones of the skull?
The majority of the other bones of the skull join with the sphenoid bone, which is situated in the middle of the skull.
What are the two mechanisms by which the bones of the body are formed and which bones are formed by each mechanism?
- Intramembranous Ossification - occurs on or within fibrous connective tissue membranes. It forms bones such as clavicle, and most of the cranial bones.
- Endochondral Ossification - it is the replacement of hyaline cartilage with bone. It forms most of the skeletal bones of the body, except for the flat bones of the skull.
What are the synovial joints being described in the video?
The synovial joints being described in the video are:
- ball-and-socket joint
- hinge joint
- pivot joint
- condyloid joint
- saddle joint
- gliding joint
Which type of synovial joint allows for the widest ranges of motion?
The ball-and-socket joint has one of the widest ranges of motion because it incorporates a ball fitting into a curved surface, allowing movement in a variety of planes and circumduction.
