(c) Hypodermis

• outermost layer of the body

• provides immediate protection for the skin

• composed of dense connective tissue

• provides shock absorption and insulation

• anchors skin to other structures

• provides nutrients for the skin

• consists of 2 layers

• also called subcutaneous tissue

Match the layers of the epidermis to their functions.

• Stratum Grandulosum

• site of stem cells that create new skin cells

• Stratum Basale

• contain lots of intermediate filaments that help resists tension; contain some dendritic cells that function in the immune system

• Stratum Corneum

• contains some cells that help form the stratum corneum & secreted glycolipids that help prevent water loss

• Stratum Spinosum

• helps protect skin against abrasion and penetration & with water proofing

Match the following components of each layer of dermis

Groups:

(a) Papillary

,

(b) Reticular

• create friction ridges that help sense of touch and with gripping

• consists of areolar connective tissue

• forms cleave lines in skin via collagen fibers

• consists of dense irregular connective tissue

• contains the dermis vasculr plexus

• contain dermal papillae that house pain and touch receptors

• contains many elastic fibers

• contains many collogen fibers

• contains most of the thickness of the dermis
