Class Summary - Today we went through all of the bones in the crainum of the skull (8); frontal, parietal, temporal, sphenoid, ethmoidoccipital. Then we started talking about the bones of the face including the maxillae (and alveolar process, and palatine process), palatine, zygomatic, lacrimal, nasal, vomer, inferior nasal conchae and the mandible (and mandibular condyle and coronoid process). We also talked about 4 major sutures including the coronal, lambdoidal, squamosal and sagittal sutures. Then we talked about the hyoid bone. This bone is the only bone on our body that does not articulate with any other bone. It is attached by ligaments and muscles from the styloid process in the skull. Today we discussed some disorders of the vertebrae including lordosis, kyphosis and scoliosis as abnormalities of the curves in the spine. We talked about the cervical 7, including the atlas and axis that allow the head to swivel and pivot. We discussed the 12 thoracic vertebrae that attach the ribs to the dorsal portion of the skeleton. We also discussed the large (because of the amount of weight it bears) lumbar portion. For the cervical, thoracic and lumbar vertebrae, each bone has; lamina, pedicle, transverse process, spinous process, body and verterbral foramen. We discussed the 5 fused boned sacrum and the coccyx. We discussed vertebral disks that are fibrocartilage that allows cushion between vertebrae. We located all on the skeleton. *** I also added review games that students can start using to practice bones on the review games page.
