The skin consists of two layers and a closely associated layer. View this animation (http://openstaxcollege.org/l/layers) to learn more about layers of the skin. What are the basic functions of each of these layers?
To write:
The different layers composing the skin.
Introduction:
The skin is composed of the three main layers, namely the epidermis, the dermis, and the hypodermis. The epidermis is the outermost layer while the dermis is present just below the epidermis. The hypodermis is the deepest layer of the skin.
Explanation of Solution
The epidermis, which is the outermost layer of the skin, functions as a waterproof barrier. It protects the tissue lying beneath it from infection, chemicals, dehydration and any kind of mechanical stress.
The dermis is present just beneath the epidermis. It is composed of tough connective tissue and include different types of the glands and the cells. The blood vessels in this layer provide nourishment to the tissues.
The hypodermis layer is made up of the connective tissue and fat. It functions by attaching the dermis to the muscles and the bones. Moreover, this layer stores fat as an energy reserve.
The skin is made up of three layers, namely the epidermis, the dermis and the hypodermis. The epidermis act as the protective layer. The dermis contains the blood vessels, and the hypodermis contains the fat.

- 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.arrow_forwardAnswer 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.arrow_forwardIdentify and explain three specific structures found in the human skin that would enable the human body to maintain homeostasis.

- Differentiate histologically the scalp skin and the palm skin. Include all the histological structures in your discussion.arrow_forwardIf you take a sterile needle and pass it through the outermost layer of the skin, no bleeding or pain occurs. Why is this possible? there is no bleeding because epidermis is avascular, right? then why is there no pain?arrow_forwardPermanent tattoos are made by injecting pigment into the skin. Into which part of the skin is the pigment injected, the epidermis or dermis? (You can answer this without research; just use your knowledge.)arrow_forward

Stores fat that can be used for food b. Helps the body in temperature regulation c. Protects the underlying tissue by acting as a "shock absorber" d. Produces melanin to protect skin from the ultraviolet rays of the sun The lower right abdominopelvic quadrant includes all of the: a. right epigastric region b. right lumbar region c. right iliac region d. right hypochondriac region An important function of the cell membrane is: a. the production of energy b. aiding in protein formation c. acting as an "identification tag" for the cell d. none of the abovearrow_forwardWhy is the skin considered an organ?
