ZOO 3734L - Gross Anatomy Lab II

Dissections of July 30 - August 2, 2001

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).
