Step by step
Solved in 2 steps
- The cuticle is a complex non-cellular layer secreted by the epidermis. It is the seat of complex processes and changes. Along this line, how are sclerotization and melanization of the integument influenced by the hemolymph? Elaborate.Name the tissue type composing the epidermis. List its major layers and describe the functions of each layer.Keratinocytes are the major cellular components of the epidermis. They are found in the four major epidermal strata: basale, spinosum, granulosum and corneum. Explain the characteristics of and the changes in the keratinocytes as they journey from the deepest to the most superficial epidermal strata.

Epidermis of the skin. Draw the LPO and HPO view of the epidermis and identify its different layers. 2.) Draw an HPO view of the dermis and label its layers/parts. 3.)What are the cell junctions in the stratum spinosum? 4.) Where are the melanocytes located? 5.) Describe the structure and development of the skin and the associated integumentary structures.6.) What are the functions of the integument and its associated structures? 7.) What do all living things have in common? 8.) What kinds of organisms are composed of prokaryotic cells? Eukaryotic cells? What kinds of cells do humans have? 9.) What is tissues?10.) List the four principal tissue types. 11.) Which is true? a. Epithelial tissues are well supplied with blood vessels. b. Connective tissues consist mostly of cells with little extracellular matrix. c. Blood is a connective tissue.EXTEND: You put lotion to your skin. You may even take vitamins and minerals for your skin and accessory organ. Discuss thoroughly the effects of your action to your integumentary system and its accessories.
- Papillary Layer: Each of these bumps or areas of the dermis that protrude into the epidermis is called a epiderma ridges What is the function of the dermal papilla? Reticular Layer: "Reticular" means network and can refer to many structures, not just reticular connective tissue. This layer of the dermis is made of mostly dense irregular connective tissue. Why?_ Draw what you see. Label the collagen fibers, fibroblast nuclei, and any hair or glands that you see. HYPODERMIS: Fibroblast: Collagen Dense regular connective tissue Dense irregular connective tissue You will see a tissue that looks like soap bubbles. Each "bubble" is a single cell with one nucleus pushed to the very edge of the bubble. The rest of the cell is filled with fat or adipose, giving the tissue its name: loose connective tissue. You also find this tissue in areas of the body where fat is stored (yellow bone marrow, greater omentum, etc.) What is the function of this tissue in this layer of the skin? Draw what you…Describe at least one interaction between skin and each of the 10 otherorgan systems.From deep to superficial, the order of the strata of the epidermis is Spinosum - granulosum - basale - lucidum - corneum Basale - granulosum - spinosum - lucidum - corneum Corneum - granulosum - lucidum - spinosum - basale Corneum - lucidum - granulosum - spinosum - basale Basale spinosum - granulosum - lucidum corneum
- OUTLINE all genes, molecules, protein factors responsible in the specification and differentiation of the epidermis and its cutaneous appendages. State the specific role/action/function of each gene, molecule, protein factor.Which of the following descriptions are correct regarding the layers of the skin? OA the epidermis has many cells, including keratinocytes and melanocytes the dermis contains many things including fibroblasts, macrophages, mast cells, collagen fibers, elastin fibers OB. and reticular fibers OC. the hypodermis is also known as superficial fascia, contains mostly adipose, and anchors skin OD. Two of the above E. All of the aboveThe Integumentary System Assignment The integumentary system is a great example of the hierarchy within the levels of anatomical organization. For this assignment, you are going to apply what you learned about these levels, specifically to the integumentary system. Below is a visual tool (you are not required to present your answer in that format) to guide you through this assignment. Your job will be as follows: Fill in all of the structures within the integumentary system that fit into each level or organization. For example, one of the structures that would fit into the "tissue level" might be areolar connective tissue. Describe how the components of each level fit together to create the next higher level in 2-3 sentences. For example, how does the buildup of the cellular level lead to the development of the tissue level? You will be compiling the components of the cellular, tissue, organ, and organ system levels, not the chemical or organism levels.
