Kinesiology 2241A/B Lecture Notes - Lecture 3: Standard Anatomical Position, Diaphysis, Tuberosity Of The Tibia
Document Summary
Muscles contract to move bones, hard bones to protect soft organs. Know the function of bones based on their shape and structure. Axial skeleton: skull, spine, and ribcage. Appendicular skeleton: the rest of the upper and lower extremities, can survive without your pelvis is either axial or appendicular.

When you add up all vertebrae you get a lot of movement. Even though each ivd may only move a little bit, when you combine them, you can get bigger movements. It protects the spinal nerve: we have a hole in each vertebrae to protect our nerves, and allow them to travel through.
