front 12 location of melanocytes and tactile (merkle) cells | back 12 stratum basale |
front 13 area where weblike pre-keratin filaments first appear | back 13 stratum spinosum |
front 14 region of areolar connective tissue | back 14 papillary layer |
front 15 *************************** | back 15 **************pics*************** |

front 17 fibers in the dermis are produced by ______________. | back 17 fibroblasts |
front 18 glands that respond to rising androgen levels are the ____________________ glands. | back 18 sebaceous and apocrine glands |
front 19 phagocytic cells that occupy the epidermis are called _____________________________. | back 19 epidermal dendritic or langerhans cells |
front 20 a unique touch receptor formed from a stratum basale cell and a nerve fiber is a __________________. | back 20 tactile or Merkel disc |
front 21 What layer is present in the thick skin but not in thin skin? | back 21 stratum lucidum |
front 22 What cell-to-cell structure holds the cells of the stratum spinosum tightly together? | back 22 desmosomes |
front 23 What substance is manufactured in the skin that plays a role in calcium absorption elsewhere in the body? | back 23 vitamin D3 |
front 24 List the sensory receptors found in the dermis of the skin: | back 24 free nerve endings for pain, temperature, messiners corpuscles for touch in the hairless skin, pacinian corpuscles for pressure |
front 25 A nurse tells a doctor that a patient is cyanotic. Define cyanotic. | back 25 A blue cast to the skin |
front 26 What does cyanotic presence imply? | back 26 Inadequate oxygenation of the blood |
front 27 What is a bedsore (decubitus ulcer)? | back 27 localized area of tissue necrosis and death |
front 28 Why do ulcers occur? | back 28 pressure areas point of increased pressure over bony areas restrict the blood supply to the area |
front 29 Produces an accumulation of oily material that is known as a blackhead | back 29 sebaceous glands |
front 30 Tiny muscles, attached to hair folicles, that pull the hair upright during fright or cold | back 30 arrector pili |
front 31 Perspiration glands with a role in temperature control | back 31 sweat gland---eccrine |
front 32 Sheath formed of both epithelial and connective tissues | back 32 hair follicle |
front 33 Less numerous type of perspiration-prouducing gland; found mainly in the pubic and axillary regions | back 33 sweat gland--apocrine |
front 34 Found everywhere on the body except the palms of hands and soles of the feet | back 34 sebaceous glands |
front 35 Primarily dead/keratinized cells | back 35 nail and hair |
front 36 Specialized nerve ending that respond to temperature, touch, etc. | back 36 cutaneous receptors |
front 37 Secretes a lubricant for hair and skin | back 37 sebaceous glands |
front 38 "sports" a lunule and cuticle | back 38 nail |
front 39 Describe two integumentary system mechanisms that help in regulating body temperature: | back 39 1. When capillary blood dlow to the skin and enhanced by nervous system controls, heat radiates from the skin surface; restriction of blood flow conserves body heat.

front 41 With what substance in the bond paper does the iodine painted on the skin react? | back 41 The starch |
front 42 Based on class data, which skin area--the forearm or palm of hand--has more sweat glands? | back 42 Palm |
front 43 Which other body areas would if tested prove to have a high density of sweat glands? | back 43 Face and Axillae |
front 44 What organ system controls the activity of the eccrine sweat glands? | back 44 Nervous system |
front 45 Why can fignerprints be used to identify individuals? | back 45 The pattern of your epidermal ridges is unique and does not change during your lifetime. Everyones fingerprint was made different, therefore this is a useful way for people to identify one another. |
front 46 Name the three common fingerprint patterns: | back 46 Loops, Arches and Whorls |
