BIOL 240 Lecture Notes - Lecture 10: Spinal Cord, Coccyx, Fibrocartilage
Document Summary
General structure: body, vertebral foramen, opening, spinal cord passing through here, vertebral arch, spinous process, arms that come from the body and meet posteriorly, considered the tips, transverse process, lamina, blade, base of blade is called pedicle. Costal facets- unique to thoracic due to needing to connect to ribs. Body of c1 adapted to the body of c2: called the atlas (c1) and axis (c2, allows them to move. Sacrum is composed of 5 vertebrae fused together. Function: protection, heart, lungs, esophagus, distal trachea major a/v. All men and women usually have 12 ribs. True ribs: 1-7, each one connects to the sternum. False ribs: 8-10, connect to true bones. Floating ribs: 11-12, basically, have no purpose, floating bones. Divided into three parts: manubrium, body, xiphoid process, where you feel for cpr. Joints ribs and vertebrae = synovial (gliding: 2 points of contact. Primary curvature: c-shape at birth, convex. Secondary curvatures: cervical and lumbar, concave.
