The Integumentary System
The dermis is composed of the papillary layer and the \_\_\_\_\_\_\_\_\_\_\_. cutaneous plexus hypodermis reticular layer epidermis
reticular layer
What structure is responsible for the strength of attachment between the epidermis and dermis? stratum corneum stratum lucidum basement membrane epidermal ridge
epidermal ridge
The two components of the integumentary system are the
1. cutaneous membrane and hypodermis. 2. integument and hypodermis. 3. epidermis and superficial fascia. 4. cutaneous membrane and accessory structures. 5. epidermis and dermis.
cutaneous membrane and accessory structures.
The type of cells that form the strata in the epidermis are dendritic cells. adipocytes. melanocytes. keratinocytes. fibroblasts.
keratinocytes
The tough "horny" superficial layer of the epidermis is known as the stratum spinosum. stratum granulosum. stratum germinativum. stratum lucidum. stratum corneum.
stratum corneum.
Large quantities of keratin are found in the epidermal layer called the stratum spinosum. stratum lucidum. stratum germinativum. stratum corneum. stratum granulosum.
stratum corneum.

insensible
Characteristics of the epidermis include: serves as UV radiation protection contains desmosomes multilayered flexible all of the answers are correct.
all of the answers are correct.
The epidermis of the skin is composed of which type of tissue?
areolar connective tissue
keratinized stratified squamous epithelium
transitional epithelium
simple squamous epithelium
nonkeratinized stratified squamous epithelium
keratinized stratified squamous epithelium
The layer of stem cells that constantly divide to renew the epidermis is the stratum germinativum. stratum granulosum. papillary layer. basal lamina. stratum corneum.
stratum germinativum.
The protein that reduces water loss at the skin surface is eleidin. keratin. melanin. mucin. collagen.
keratin.
Melanocytes _____________.
1. secrete melanin from the basal surface 2. store melanin in melanosomes 3. manufacture melanin from the amino acid alanine 4. are located in the stratum corneum
- store melanin in melanosomes
An albino individual lacks the ability to produce eleidin. melanin. perspiration. keratin. carotene.
melanin.
Cyanosis signifies that a patient has oxygen-starved skin. has an allergic reaction. has been exposed to cyanide. has been kept out of the sun. has had too much sun.
has oxygen-starved skin.
Jaundice is indicated by an orange skin coloration. a reddish skin coloration. a bluish skin coloration. a yellowish skin coloration. a brown skin coloration.
a yellowish skin coloration.
Types of skin cancers include squamous cell carcinoma. malignant melanoma. basal cell carcinoma. actinic keratosis. squamous cell carcinoma, malignant melanoma, and basal cell carcinoma.
squamous cell carcinoma,
malignant melanoma,
and basal cell carcinoma.

The layer primarily responsible for the strength of the skin is the \_\_\_\_\_\_\_\_\_\_ layer. papillary epidermal reticular hypodermal
reticular
The skin layer just beneath the stratum germinativum is the \_\_\_\_\_\_\_\_\_\_ layer. reticular epidermal hypodermal papillary
papillary
*stratum germinativum = stratum basale
