| 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 complete 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). |

| N.B. | Like the neck, many of the structures of the head, and particularly the brain, are of Greek rather than Latin origin. However (or hopefully), as shown below, these terms are a little less intimidating if you understand their etymology. |
