Final Exam Study Guide PDF

Summary

This document is a study guide, not a past paper, for a final exam. It covers various topics related to homeostasis, cellular organization, tissues, the integumentary system, nervous system, and the autonomic nervous system. Extensive details and diagrams make the guide very thorough.

Structure: top/superficial layer; 15-30 cells thick. Composed of keratin. Dead and durable, water-resistant, continually shed and replaced Function: Protection against external environment 2. Structure: ONLY in thick skin, absent in thin skin like palms of hands or soles of feet Function: Extra protection against friction or abrasion 3. Structure: 3-5 layers of dense keratin-filled cells beginning to die and losing organelles. Function: Keratin production 4. Structure: 8-10 cell layers of keratin-filled, spiny-looking cells Function: Spiny adhesions hold cells together 5. Structure: 1-2 cell layers comprised of stem cells, melanocytes, and sensory/Merkel cells\ Function: Stem cells generate all other layers of the epidermis. Merkel cells sense light touch ACRONYM TO REMEMBER: Can Lucy Give Some Blood? - 1. Areolar Connective Tissue: contains blood vessels and sensory cells Dermal Papillae: forms epidermal ridges that lead to *fingerprints* 2. Dense Irregular Connective Tissue: Protects against multidirectional stress Base of hair follicles and glands - - - - - 1. - - 2. - - - 3. - - - 4. - - - 5. - 6. - 7. - - - 8. - - 9. - - 10. - 11. - 1. - 2. - - - - 3. - 4. - - - **Nervous Tissue and Sensory Division** 1. - - - - - - - - 2. - 3. - 1. 2. 3. 4. - - - - - - 5. - 6. - - - - 7. - - 8. - - - - - - **Thermoreceptors** - Changes in Temp.
