Anatomy: Dermis

The dermis is composed of the papillary layer and the ___________. | epidermis | | cutaneous plexus | | hypodermis | | -reticular layerThe reticular and papillary layers together compose the dermis. |
What structure is responsible for the strength of attachment between the epidermis and dermis? | stratum corneum | | basement membrane | | -epidermal ridge | | stratum lucidumThe deeper the epidermal ridge, the stronger the attachment. |
The type of cells that form the strata in the epidermis are | Dendritic cells. | | -keratinocytes. | | adipocytes. | | melanocytes. | | fibroblasts. |
The tough "horny" superficial layer of the epidermis is known as the | stratum spinosum. | | stratum lucidum. | | stratum granulosum. | | -stratum corneum. | | Stratum germinativum. |
Large quantities of keratin are found in the epidermal layer called the | stratum spinosum. | | stratum lucidum. | | stratum granulosum. | | -stratum corneum. | | stratum germinativum. |
Water loss due to evaporation of fluid that has penetrated through the skin is termed ________ perspiration. | sensible | | latent | | -insensible | | inactive |

The layer of the skin that provides a barrier against bacteria as well as chemical and mechanical injuries is the | dermis. | | stratum corneum. | | -epidermis. | | subcutaneous layer.Water loss from insensible perspirationIs approximately .5 liters a dayThe epidermis of the skin is composed of which type of tissue?keratinized stratified squamous epitheliumThe layer of stem cells that constantly divide to renew the epidermis is the | | is approximately 0.5 liters a day. | | depends on apocrine sweat glands. | | is negligible. | | always exceeds sensible perspiration. | | is too small to be measured reliably. | | Stratum germinatiumThe protein that reduces water loss at the skin surface isKeratinWhile walking barefoot on the beach, Joe stepped on a
