assemble assemble assemble assemble 2. Based on the observations, what can you say about the distribution of sudoriferous glands in . Thick vs. thin skin Hirsute vs. non-hirsute skin 3. What would happen if you had performed this experiment after exercising? MAKE THE CONNECTION 1. Why are many injections given in the hypodermis? Permanent tattoos are made by injecting pigment into the skin. Into which part of the skin is the pigment injected? 2. The epidermis is composed of many layers of keratinized epithelial cells that act as a barrier to infection and to absorption of water through the skin. Cortisone is a steroid that is applied to the skin to reduce inflammation and acts on the cells within the dermis. Explain hovw cortisone can pass through the epidermis to reach the dermis. 3· 4. Burns are classified into three types. Give the depth of the skin that is affected and general signs and symptoms for each type of burn. First degree: Second degree: Third degree:Explanation / Answer
2. Sweat glands, also known as sudoriferous or sudoriparous glands.There are two main types of sweat glands that differ in their structure, function, secretory product, mechanism of excretion, anatomic distribution, and distribution across species.
1Eccrine sweat glands : Eccrine glands are present throughout the skin surface, especially on the palms of the hand, the soles of the feet, and the forehead. Like hair and nails, they are derived from the epidermis. They are coiled glands that lie in the dermis, with the duct opening to a pore on the skin surface, where the sweat is released
2 Apocrine sweat glands : Apocrine glands are usually associated with hair follicles and are activated in densely hairy areas like armpits and genitals. They are larger than merocrine sweat glands and lie deeper in the dermis, sometimes even reaching the hypodermis
Thin skin actually has a thicker dermis than thick skin, which makes thin skin easier to suture, if it gets damaged. Thin skin also has fewer eccrine/merocrine sweat glands.
1.Medications given by subcutaneous injections (hypodermis )are absorbed more slowly than drugs given by intravenous injection, making subQ injections an ideal route for many drugs.
2. For making a permanent tattoo, the needles penetrate past the epidermis into the underlying dermis, leaving behind pigment in the entire area. The living dermis is composed of collagen fibers, nerves, sweat glands, sebaceous glands, blood vessels and basically everything that keeps skin connected to the rest of the body.
3.Cortisone is a lipid soluble molecule hence can pass through the epidermis.It is applied to the skin to reduce inflammation. cortisone acts on cells within the dermis and can travel through unbroken epidermis to reach cells in the dermis.
4. First-degree burns are considered mild compared to other burns. They result in pain and reddening of the epidermis (outer layer of the skin).
