Question
**Human Skin Layers and Regions** **2. Match the number on the figure to the specific skin layer or region that identifies it.** **Image Description:** The image presents a microscopic view of the human skin layers. The layers are labeled with numbers 1 through 4. - **1:** The top layer which appears wavy due to ridges and folds, labeled to the right of the skin section. - **2:** The second layer beneath the wavy top layer, extends from the end of layer 1 to the beginning of layer 3. - **3:** The third layer located deeper within the skin structure. - **4:** The fourth and deepest layer shown in the image. **Names of Layers:** - ____ Epidermis (outermost layer) - ____ Dermis (layer below epidermis) - ____ Papillary region (upper part of the dermis) - ____ Reticular region (lower part of the dermis) **Directions:** Name the specific tissue type(s) that compose the epidermis, dermis, and hypodermis (subcutaneous layer). **Skin Layer/Region:** 3. Epidermis **Tissue Type(s):** _____________________________________________ 4. Dermis: - Papillary region **Tissue Type(s):** _____________________________________________ - Reticular region **Tissue Type(s):** _____________________________________________ 5. Hypodermis (subcutaneous layer) **Tissue Type(s):** _____________________________________________ **Graph/Diagram Explanation:** The diagram is a highly magnified histological (microscopic) section of human skin, showing the organization of different layers. Each layer has distinct characteristics and functions: - **Epidermis:** The outermost protective layer, composed mainly of keratinized stratified squamous epithelium. - **Dermis:** Composed of two regions: - **Papillary region:** The uppermost part of the dermis, containing thin collagen fibers, blood vessels, and sensory neurons. It often appears wavy or ridge-like. - **Reticular region:** The denser, deeper part of the dermis, composed of thicker collagen fibers and elastic fibers providing strength and elasticity. - **Hypodermis:** The deeper subcutaneous layer, not labeled in the image, primarily consisting of loose connective tissue and fat cells that provide insulation and cushioning.
