Layers of the skin
| Question | Answer |
|---|---|
| Also known as hypodermis. Subcutaneous adipose tissue located beneath the dermis: protective cushion; energy storage for the body. decrease and thin with age | Subcutáneos layer |
| Also known as adipose tissue. This layer is 80% fat creates a protective cushion that gives contour and smoothness to the body | Subcutis tissue |
| True skin, is the support layer of connective tissues above the hypodermis. Supplies the skin with oxygen and nutrients | Dermis |
| Two layers of the dermis | Reticular layer. Papillary layer |
| Deeper layer of the dermis surprise the slim with oxygen. is comprised mainly of collagen and elastin. Damage to These elastin fibers is the primary cause of sagging wrinkles and aging | Reticular layer |
| Top layer of the dermis; next to the epidermis. Connect the dermis with the epidermis | Papillary layer |
| Membranes of ridges and grooves that attach to the epidermis; contains nerve endings and supplies nourishment through capillaries to skin and follicles | Dermal papillae |
| Cone shaped elevations at the base of the follicle that fit into the hair bulb, papillae are full with tissue that contains the blood vessels and cells necessary for hair growth and follicle nourishment | Hair papillae |
| Protein substance of complex fibers that gives skin its strength and is necessary for wound healing | Collagen |
| Fibrous protein that forms elastic tissue and gives skin its elasticity | Elastin |
| Work to maintain and support collagen and elastin in the cellular spaces | |
| GAGs. Glycosaminoglycans | |
| Remove waste products, bacteria and excess fluid | Lymph vessel |
| Outermost layer of the skin. Epithelial tissue that covers our body | Epidermis |
| How many layer is the epidermis composed | 5 layers |
| 5 layers of the skin (epidermis) | Stratum corneum. Stratum lucidum. Stratum granulosum. Stratum spinosum. Stratum germinativum |
| The germination or growth layer. Also know as basal cell layer .active layer of the epidermis above the papillary layer of the dermis | Stratum germinativum |
| The spiny layer. Layer of the epidermis above the stratum germinativum (basal) layer containing desmorones, the intercellular connections made of protein | Stratum spinosum |
| Also know as granular layer. Layer of the epidermis composed of cells filled with keratin that resemble granules: replaces shed from the stratum corneum | Stratum granulosum |
| The clear cells. Present only where the skin is thick, on the soles of the feet and the palms of the hand | Stratum lucidum |
| The horny cell | Stratum lucidum |
| Deeper layer of the dermis that supplies the skin with oxygen and nutrients;contains fat cells, blood vessels,suforiferous (sweat) glands hair follicle lymph arrector pili muscle | Reticular layer |
