| the cells found only in the stratum basal and they make the pigment in your skin | melanocytes |
| which layer of the epidermis is found only in the thick skin | stratum lucidum |
| the most superficial layer of the epidermis | stratum corneum |
| this layer of the epidermis contains 3-5 layers of flat keratinocytes which contain dark staining keratohyalin granules | stratum granulosum |
| finger like extensions of the dermis | dermal papillae |
| what are the two zones of the dermis | papillary and reticular layers |
| what is the layer called underneath the skin | hypodermis or subcutaneous tissue |
| what are the two main forms of melanin | eumelanin and pheomelanin |
| the sweat glands that occur in the groin, anal region, axilla and areola. | apocrine glands |
| the sweat glands widely distributed over the entire body, especially abundant on the palms, soles and forehead | eccrine sweat glands |
| the glands that produce an oily secretion called sebum | sebaceous glands |
| modified apocrine glands found in the external ear canal, produce ear wax | ceruminous glands |
| system that contains the skin, hair and nails | integumentary system |
| immune cells of the epidermis found in stratum spinous and stratum granulosum | dendritic cells |
| what are the functions fo the skin | resistance to trauma and infection, barrier to things such as water, vitamin D synthesis, sensation, thermoregulation, nonverbal communication |
| the layer of the epidermis named for an artificial appearance created during microscope preparation | stratum spinous |
| lipid filled granules that help as a water barrier | lamellar granules |
| the layer of skin which stretch marks can develop | dermal layer (reticular) |
