Watch this video to view a rotating and exploded skull with color-coded bones. 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 bone in the video is the Sphenoid bone.
What are the two mechanisms by which the bones of the body are formed and which bones are formed by each mechanism?
- Intramembranous ossification - Directly converts the mesenchymal tissue to bone. It forms flat bones of the skull, clavicle and most of the cranial bones.
- Endochondral ossification - Mesenchymal tissue transforming into a cartilage intermediate, which is then later replaced by bone and forms the remainder of the axial skeleton and the long bones
What are the synovial joints being described in the video?
- Ball and socket joint
- Pivot joint
- Hinge joint
- Condyloid joint
- Gliding joint
- Saddle joint
Which type of synovial joint allows for the widest ranges of motion?
- Ball and socket joint allows for the widest ranges of motion due to it have a ball joint design making it go in multiple directions.
