Module 4.1: Skin Anatomy and Some Physiology
In this module you will begin exploring our first body system, the skin. There's much more to the skin than meets the eye and its homeostatic mechanisms are even more important. Begin to look for connections to other body systems, as we will be making connections from one to the next throughout the year.
Module 4.1 Warm-Up : Skin Anatomy
- Directions: Find out the basic physiology and importance behind several important skin features.
Essential Vocab:
Hypodermis,
superficial fascia, epidermis, keratinocytes, keratin, melanocytes, melanin,

coreum, dermis, papillary layer, dermal papillae, friction ridges, reticular

Module Objectives:
1.1 – Name the tissue types composing the dermis and the epidermis. List the major layers of each and describe their function.
