| N.B. | In each dissection some names appear in parentheses. These are structures that may not readily be found during your dissection, i.e., look for them but do not spend too much time on them so that you have time to comlete the laboratory. Many of these structures will be exposed more completely in future dissections or are best observed in your atlas. Also, there will be important structures listed that are not found in your dissector (Hansen, 1998); information about these items can be found in your text (Jenkins, 1998; Moor and Augur, 1996; Stern, 1997). |

| Find the following structures using your atlas, dissector (Hansen pp. 63-64) and text (Jenkins pp. 63, 199 - 214; Moore and Agur pp. 190-203, 281-284; pp. Stern 2-5) as a guide. | |
| N.B. | You will be responsible for distinguishing between a cervical, thoracic, lumbar and sacral vertebra: You will also be responsible for identifying [under isolated conditions] the following vertebra: C1, C2, T12. You must also be able to side a rib and distinguish R1 from all other ribs (R2-12). |

| This linked figure illustrates the homologies of the vertebral elements and may help you to understand variation in vertebral morphology. | |
| An online review of vertebral column (actually back) anatomy can be found at the University of Newcastle . While the osteology and arthrology sections of this tutorial are good, the sections on sections on myology and neurology are incomplete. The applied anatomy section illustrates clinical applications (prolapsed intervertebral discs, lumbar puncture, epidural anesthesia), some with movies (mpg format). | |
