- A Font M Paragraph Styles Describe and explain four (4) reasons why the skin contributes to the body's homeostasis. Dictate How is the epidermis different from the dermis - give me four (4) reasons? 1 of 6 314 words IX Editor Contrast keratin and melanin in terms of their structures and functions. 255 Contrast sebaceous and sudoriferous glands in terms of their locations in the skin and what they make in the skin. Focus = Photo by Ev Tchebotarev MAR 20"The deeper within the dermis or subcutaneous tissue any dark pigment is located, the bluer the pigment appears because of the light-scattering effect of the overlying tissue. " TRUE FALSEDr. Cortez is examining a microscope slide of a tissue sample of skin from a patient with large fluid-filled blisters. What does she see on the slide that would lead her to suspect the patient has bullous pemphigoid? O There is a split between the papillary and reticular layers of the dermis. The stratified squamous epithelium of the epidermis lacks defined layers and the cells of the stratum basale appear squamous in shape rather than cuboidal. O There is an obvious split between the epidermis and the underlying dermis. O The stratum corneum is separated from the stratum germinativum.
- Answer the following statements by choosing the correct layer of skin. 1. The epidermis is a epithelial tissue that is stratified squamous. 2. The [Select ] is responsible for the synthesis of cholecalciferol. 3. The [Select ] * contains melanocytes. 4. The [Select ] * aids in regulating our body temperature by providing insulation. 5. The [Select ] * is where most of the nerve endings, and hair follicles are located.One important function provided by the layer of epidermis indicated by the arrow is: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…
- 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.Intradermal melanocytic pigmented nevus H&E staining Mark the corresponding elements in the picture: 1 - epidermis 2 - dermis 3- nevus-cells 4- accumulation of melanin Description: Specify the localization of melanin accumulationsPlease answer together 1. Patient A and Patient B suffered different degrees of burn during an accident. Patient A had only the epidermis layer destroyed, while Patient B had both the epidermis and the dermis layers destroyed. Without skin grafting, will body hair grow back on Patient A? How about Patient B? Explain 2. Name 3 different types of accessory structures in the skin that play an important role in maintaining homeostasis? Give specific examples to show how these accessory structures can maintain homeostasis through negative feedback.
