Top layer of the epidermis ANS - stratum corneum
bottom layer of epidermis ANS - stratum basale
Purpose of stratum corneum ANS - Protects underlying cells and tissues from dehydration
and entry of fluids
what do the cells in the stratum hassle do? ANS - divide, multiply, and migrate toward the
epidermal surface
What lies below the epidermis and provides tensile strength and protection for the
underlying muscles, bones, and organs ANS - dermis
the only distinctive cell type in the dermis and are responsible for collagen formation ANS -
fibroblasts
what protects the patient from invading organisms ANS - intact skin
disruption of the integrity and function of tissue in the body ANS - wound
types of wounds ANS - surgical incision, abrasion, puncture/penetrating injury, avulsion,
crush injury, blunt force trauma, and ulcer
caused by a trauma or a surgical incision. The wound edges are clean and intact ANS - acute
Wound that fails to proceed through an orderly and timely process to produce anatomical
and functional integrity ANS - chronic
what events happen after an injury occurs ANS - control blood loss, establish bacterial
control and seal the defect
wounds are shallow and has loss of the epidermis and possibly the dermis layers of the skin
ANS - partial thickness wound repair
How do partial thickness wounds heal? ANS - epidermal regeneration

repair
