Functions of the Skin Flashcards
What are all the Functions of the Skin?
Thermoregulation, Blood Reservoir, Protection, Cutaneous Sensation, Excretion and absorption, Creation of Vitamin D.
What are the types of “Wound Healing”?
Epidermal wound healing, Deep Wound healing.
What are the steps to Epidermal wound healing?
1: The cells enlarge and migrate across the wound after breaking off the basement membrane.
2: After the sheets of cells meet they stop migrating due to a response called “Contact Inhibition”, Moving of the cells stops completely after all the layers have met with each other.
What are common types of Epidermal Wounds are there?
This includes:
Abrasions, minor burns.
What is the First step to Epidermal Wound healing?
First the cells on ether side of the cut move toward each other in a process called “Contact Inhibition”.
When does the “Epidermal Growth factor” occur in the Epidermal Wound Healing?
This will happen when all the
When does “Deep wound healing occur”?
This is when an injury extends into the Dermis and or the Subcutaneous layer.
When does “Deep wound healing occur”?
This is when an injury extends into the Dermis and or the Subcutaneous layer.
This is because multiple tissue layers must be repaired.
What are the 4 phases that Deep wound healing occurs in?
Inflammatory, Migratory, Proliferative, Maturation.
What is involved in the first Step of Deep wound healing of the skin?
This is the Inflammatory process:
A blood clot forms in the wound and loosely unites the wounds edges.
The “Inflammation” portion of this step involves a vascular and cellular response that helps fight microbes and prepare dying tissue for repair.
What do the last 3 steps to the Deep wound healing involve?
The 1st step involves Inflammation.
The last 3 steps involve the repairing of the Tissue.
What does the 2nd step in the Deep wound healing process involve?
In the Migratory Phase the blood clot becomes a scab and the Fibroblast form scar tissue and the Damaged blood vessels start to regrow.
What is the name of the Tissue in Migratory phase of the deep wound healing that fills in the scab/ wound?
Granulation tissue.
What occurs in the Proliferating phase of the Deep wound healing process?
Extensive growth of the epithelial cells beneath the scab and deposition of collagen fibres randomly and continual growth of the blood vessels.
What does the Maturation phase of the Deep wound healing consist of?
This is when the Scab falls off and
