| Callus | Continued pressure on any part of the skin can cause it to thicken and develop a |
| sweat and oil glands | Appendages of the skin include hair, nails, and |
| eyelids | The skin structure is generally thinnest on the |
| hair follicles | The on the scalp has larger and deeper |
| epidermis layer | outer most layer of the skin; 1st layer also called cuticle |
| blood vessels | The epidermis layer of the skin does not contain |
| stratum germinativum | also known as the basal cell layer, the deepest live layer of the epidermis that produces new epidermal skin cells and is responsible for growth |
| melanocytes | the dark special cells that protect sensitive cells and provide color to the skin and melanin- forming cells |
| stratum granulosum | granular layer of the epidermis |
| stratum corneum | outer layer of the epidermis |
| keratiin | fiber protein that is the principal component of hair and nails |
| stratum lucidum | clear, transparent layer of the epidermis |
| dermis | underlying or inner layer of the skin; 2nd layer also called the derma, corium, cutis, or true skin |
| papillary layer | outer layer of the dermis, directly beneath the epidermis |
| reticular layer | deeper layer of the dermis that supplies the skin with oxygen and nutrients; contains cells, vessels, glands, and follicles |
| subcutaneous tissue | tissue that gives smoothness and contour to the body and provides a protective cushion fatty layer is |
| lymph | the clear fluid that removes toxins and cellular waste and has immune function is |
| arrector pili muscle | motor nerve fibers attached to the hair follicle that can cause goose bumps are the |
| secretory nerve fibers | distributed to the sweat and oil glands of the skin regulate the secretion of perspiration and sebum are |
| nerve endings (sensation) | Basic sensations such as touch, pain, heat, cold, and pressure are registered by |
| genes | the amount and type of pigment produced by an individual is determined by |
| pheomelanin and eumelanin | two types of melanin producedby the body are |
| dermis layer | skin gets its strength, form, and flexibility from flexible fibers found within the |
| collagen | fibrous protein that gives the skin form and strength |
| elastin | a fiber that gives skin its flexibility and elasticity is |
| sudoriferous glands | sweat glands of the skin regulate boby temperature |
| secretary coil | coiled base of sweat glands tubelike duct that ends at the skin surface to form the sweat pore also fungus is the |
| hair follicle | the sebaceous or oil glands are connected to the |
| secretion and absorption | the principal functions of the skin are protection, sensation, heat regulation, excretion, and |

| base cell layer | also known as the stratum germinativum later; the deepest, live layuer of the epidermis that produces new epidermal skin cells and is responsible for growth |
| papillary and reticular layer | the dermis is comprised of two layers |
| epidermal dermal junction | the top of the papillary layer where it joins the epidermis is called |
| secretion | sebum, or oil, is secrected by the sebaceous glands |
| tactile corpuscles | small epidermal structures with nerve endings that are sensitive to touch and pressure |
| vitamin A | aids in the health, function, and repair of skin cells |
| vitamin C | is needed for proper repair of the skin and various tissues keeps the skin healthy and firm important in fighting the aging process |
| vitamin D | promotes the healthy and rapid healing of the skin |

| soles of the feet | have the thickest skin |
| tactile corpuscles | small epidermal structures with nerve endings that are sensitive to touch and pressure |
| stratum granulosum | cells that are almost dead and pushed to the surface to replace cells are shed from the |
