15 Pre-lab Assignments The pre-lab assignments are designed to prepare you for your upcoming lab. First, review the relevant chapter in your textbook. Next, read through each lab activity (introductory material and procedure). Then complete the cor- responding pre-lab assignment for each activity. Pre-lab ASSIGNMENT 15A Overview of the Special Senses Match the location of each sensory receptor with the appropriate receptor type by writing the correct letter in the numbered blanks. 1. Gustatory cell 2. Photoreceptor 3. Hair cell 4. Olfactory neuron Pre-lab ASSIGNMENT 15B A. Eye B. Nasal cavity C. Ear D.
