Q Unit 11: Discussion Pick 2 of the bulleted prompts below to write about in this week’s discussion. Unit 11 – Special Senses • Differentiate the major classes of general senses. • Identify the structure and functions involved in olfaction & which cranial nerve would this involve? • Identify the structure and functions involved in gustation &which cranial nerves would this involve? • Identify the structure and functions involved in vision & which cranial nerves would this involve? • Identify the structure and functions involved in hearing & which cranial nerve would this involve? • Describe 4 homeostatic imbalances of the senses and discuss what is occurring physiologically in a person with the condition. ________________________________________________________________________ General Discussion Requirements Your initial response to the Prompt below should be posted no later than midnight on Day 4 of the academic week. Your input should be in your own words, demonstrating your understanding and comprehension of the topic. Copying and Pasting from the internet will result in a zero. It is expected that you will include both in-text and final references properly formatted in APA on all initial discussion postings. For help with this refer to the Academic Writer tab to the left of your screen. Then, I want to see you respond to your classmates in the middle of the week (try for Day 4, 5, or 6). The purpose here is to generate discussion to further explore the topics...ask questions, add insight, agree or disagree, etc. Of course, all discussion should be positive and professional. Do not complete all discussions requirements in one sitting, ideally; you should post in the discussion 3-4 different days throughout the week. If you have questions about this participation requirement, post them to the Course Questions Forum. Refer to the syllabus for a complete breakdown of the expectations.
