Part of Lesson Plan: Body Mechanics

Activity Overview / Details

Display the picture of the spine on an overhead transparency as students are instructed on the anatomy.

Back has three natural curves

1. cervical curve - neck
2. thoracic curve - middle back
3. lumbar curve - low back

These three curves need to stay in proper alignment (proper positioning of parts in a line)

Good posture - proper alignment of the spine ( display picture of proper alignment)

vertebrae - 33 individual bones make up spine

discs - cartilage which seperate vertebrae, absorb shock

back muscles - support the spine, not used for lifting
