WOUND CERTIFICATION EXAM SCRIPT 2026
COMPLETE QUESTIONS AND CORRECT
SOLUTIONS
◉ External skin surface. Answer: Stratum basale the granular layer,
Stratum spinosum the spiny layer, Stratum granulosum the granular
layer, Stratum lucidum the clear layer, Stratum corneum the horny
layer
◉ Stratum basale. Answer: The Deepest cell layer; contains
continuous dividing cells.
◉ Stratum spinosum. Answer: The Epithelial cell layer located
between the stratum basale and stratum granulosum.
◉ Stratum granulosum. Answer: Epithelial cell layer located
between the stratum spinosum and stratum lucidum.
◉ Stratum lucidum. Answer: Epithelial cell layer located between
the stratum granulosum sand stratum corneum.
◉ Stratum corneum. Answer: Outermost epithelial cell layer;
consists of dead keratinocytes
,◉ Basement Membrane. Answer: Forms junction between dermis
and epidermis.
◉ Cells of the Epidermis:. Answer: Keratinocytes create toughness,
Langerhans' cells offer protection, Melanocytes produce melanin,
Merkel's cells offer touch sensation
◉ Functions Of skin. Answer: Prevents excessive loss of fluids;
melanin; ph slightly acidic 4.5- 5; maintain Temperature vasodilation
to dissipate heat; vasoconstriction to retain heat; maintenance of
calcium and phosphorus levels in the bone and blood
◉ Epidermal Appendages:. Answer: Sebaceous glands secret sebum,
Hair follicles, Eccrine sweat Glands produce sweat, regulate
temperature and eliminate waste; Apocrine sweat glands produce
body odor; Nails
◉ Dermal Layers:. Answer: 2; Papillary dermis anchor dermis with
finger like projections; Reticular dermis lower layer offers strength
◉ Collagen, Elastin:. Answer: Collagen is A protein which gives skin
tensile strength. Type 1 Collagen 77-85%; Type 3 Collagen - 15-23%;
Elastin- Protein which provides the skin with its recoil
, ◉ Dermal cell Types:. Answer: Fibroblasts produce collagen, elastin,
granulation tissue and growth factors. Macrophages and White
Blood Cells fight infection; Mast Cells initiate inflammation response.
◉ Desmosomes. Answer: Specialized structures which bind adjacent
keratinocytes to one another and give cohesion to each layer during
its upward progression
◉ Dermis. Answer: Supports and nourishes epidermis, Thick, dense ,
fibroelastic, connective tissue. Highly vascularized, Contains nerves,
sweat glands, sebaceous glands, hair follicles, Produced in bone
marrow
◉ Extra cellular matrix (ECM). Answer: Largest component of
dermis, gel like matrix produced by the cells that it surrounds
◉ Subcutaneous tissue. Answer: Lies beneath the dermis and
composed of adipose tissue and fascia, provides cushioning.
◉ Fascia. Answer: White shiny in appearance, sheath like covering
for muscles, nerves, and blood vessels
◉ Colelnagenase. Answer: Endogenous enzyme that breaks down
collegen during maturation and remodeling phase
