BSC 2346 Module 09 Lab Worksheet: Special Senses and Eyeball Dissection.Introduction This week’s lab will focus on the special senses of vision, hearing, balance, smell and taste. Objectives Objectives for this week’s lab include: 1) Identify the anatomical components of the special senses, 2) Identify the anatomical structures of the eye through dissection, and 3) Analyze the function of the special senses.
