Document Summary

Chapter 7 the skeletal system: the axial skeleton. Transverse process joint that articulates with ribs. Costal margin made up of common cartilage. Tubercle of rib 8 will articulate with thoracic vertebra 8. Costal groove thin, rounded space that protects the vein artery and nerve that are innervating intercostal muscle. Mastoid process, nuchal line (raised ridge on occipital bone) Flex cervical sine, rotation towards opposite direction of contracting muscle. Extending vertebral column, lateral rotation of cervical spine. Raises scapula, pulls scapula towards (flexing), look up. Transverse process raises scapula e rotate head opposite to contracting muscle. Together extend head single rotate head to same side as contracting muscle. Together extend head single laterally flex and rotate head to same side of contracting muscle. Articular processes of c4-c6 and transverse of c7- Articular processes of c4-c7 and transverse processes of t1-t4. Section on back medial to the inferior part of scapula where there are no superficial muscles covering ribs.
