Step by step
Solved in 2 steps
- Collagen lends ________ to the skin. elasticity structure color UV protectionThe papillary layer of the dermis is most closely associated with which layer of the epidermis? stratum spinosum stratum corneum stratum granulosum stratum basaleThe papillary and reticular layers of the dermis are composed mainly of ________. melanocytes keratinocytes connective tissue adipose tissue
- Projections of the dermis toward the skin surface are called ______________ .Place the layers of the epidermis in order (1–5) from theoutermost layer to the layer attached to the dermis by thebasement membrane._____ stratum spinosum_____ stratum corneum_____ stratum basale_____ stratum lucidum_____ stratum granulosumNumber the strata of thick skin epidermis from deepest (1) to most superficial (5). _____ Stratum spinosum _____ Stratum corneum _____ Stratum basale _____ Stratum lucidum _____ Stratum granulosum
- Papillary Layer: Each of these bumps or areas of the dermis that protrude into the epidermis is called a epiderma ridges What is the function of the dermal papilla? Reticular Layer: "Reticular" means network and can refer to many structures, not just reticular connective tissue. This layer of the dermis is made of mostly dense irregular connective tissue. Why?_ Draw what you see. Label the collagen fibers, fibroblast nuclei, and any hair or glands that you see. HYPODERMIS: Fibroblast: Collagen Dense regular connective tissue Dense irregular connective tissue You will see a tissue that looks like soap bubbles. Each "bubble" is a single cell with one nucleus pushed to the very edge of the bubble. The rest of the cell is filled with fat or adipose, giving the tissue its name: loose connective tissue. You also find this tissue in areas of the body where fat is stored (yellow bone marrow, greater omentum, etc.) What is the function of this tissue in this layer of the skin? Draw what you…The form and pattern of skin ridges are determined bythe (epidermis, dermal papillae).The papillary layer of the dermis is most closelyassociated with which layer of the epidermis?a. stratum spinosumb. stratum corneumc. stratum granulosumd. stratum basale
