Document Summary
Describe a typical vertebra: spinous process, lamina, pedicle, vertebral foramen, articular facets, articular process, transverse process. Made of fibrocartilage -> compressible wk 7 page 1. Screen clipping taken: 4/04/2018 10:53 am wk 7 page 2. Identify the unique features of a typical cervical vertebrae: transverse foramen, small body, large vertebral foramen, bifid process. Bifid spinous process (c3-c6, not c1 and c7), resembles fish tail. Vertebral foramina large and triangular - to accommodate larger spinal cord which supplies upper limbs, more complex movements and more innervation. Describe the c1 and c2 vertebra and the atlanto-occipital and atlanto-axis joints and relate this to movements they perform: flexion, extension, rotation. Screen clipping taken: 4/04/2018 10:59 am wk 7 page 4. Describe and locate the main muscles of the neck: anterior and posterior compartments. Anterior: suprahyoids and infrahyoids, posterior: scalenes and the sternoceidomastoid muscle, summarise their action and nerve supply. Continues with tracheal rings of cartilage wk 7 page 6.
