Class Summary - Students can start today doing this activity: http://www.purposegames.com/game/parts-of-the-skull-side-quiz Today we went over the bones of the skull worksheet. Today 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. Students were assigned a worksheet on the axial skeleton due tomorrow after a quiz on the skull.
Homework - Axial Skeleton Worksheet, Quiz on Skull Bones and Vertebrae Wednesday
Objectives - Students will identify the bones of the vertebrae and the hyoid bone.
