- Collagen lends ________ to the skin. elasticity structure color UV protectionWhat is integument. Describe three layers of integument and its function in detail.The 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.
- The human integumentary system is critical for maintaining homeostasis. Identify and describe three distinct structures found in the human skin that aid in the body's homeostasis maintenance.Elaborate thoroughly: 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?Answer the following questions about the integumentary system. Name each of the five sublayers of the epidermis in order from superficial to deep. For each layer, describe one unique characteristic and name the type of cells found there. Next, make a sentence to help you remember the order of the layers. Use the first letter of the second part of each layer (for example use the letter G for stratum granulosum) since they all start with "stratum." Put together a sentence with 5 words that start with the letters. For example I think "Please Make A Taco" to help me remember prophase, metaphase, anaphase and telophase.
- 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…Draw what you see. Distinguish between the keratinized strata (1-2) and non-keratinized strata (3-5). Draw what you see. Disti individual cells and nuclei Keratinized strata Non-keratinized strata If it is thick skin, the epidermis has 5 layers or "strata." Where is thick skin found?palms of hand If it is thin skin, the epidermis has esc Skin, thick trichrome stratum granulosum Squamous nuclei stratum corne strata and is found everywhere else! stratum spi and soles of feet you look at thin skin, you may also see a different cell type called melanocytes in the strat roduce Malina pigment that blocks UV light.Part C. SKIN: Remember that epithelial tissues are more darkly stained because they have more cells? This dark colored ribbon and the flaking dead layers above it is the epithelium of the epidermis. The thicker, lighter colored areas are the connective tissues of the dermis and hypodermis. EPIDERMIS: The epidermis is made up of 5 layers or strata but they combine to form one epithelial tissue. You should see disti areas of keratinized strata (1-2) and non-keratinized strata (3-5). 1. Stratum e 2. Stratum Susum 3. Stratum Stratum cum Stratum Corneum How can you tell from looking at the cells in the strata whether they are keratinized or non-keratinized? 4. 5. ulosum What shape of cell do you see in the first living layer (3)?_______ Tissue names come from the apical layers of cells, in this case, the shape of the cells in the stratum granulos Using this information, name the tissue of the epidermis: + 1 if mentioned keratinized Why does the skin need this type of tissue to cover the…
