QUESTIONS WITH SOLUTIONS GRADED A+
⩥ Integumentary Function: Protection.
Answer: Protects against UV light, microorganisms, and water loss.
⩥ Integumentary Function: Sensation.
Answer: Sensory receptors detect heat, cold, touch, pressure, and pain.
⩥ Integumentary Function: Temperature Regulation.
Answer: Modulates blood flow through the skin and controls activity of
sweat glands.
⩥ Integumentary Function: Vitamin D Production.
Answer: Produces a molecule made in the skin when exposed to UV
light.
⩥ Integumentary Function: Excretion.
Answer: Eliminates small amounts of waste products.
⩥ Epidermis.
,Answer: Superficial layer of the skin composed of stratified squamous
epithelial tissue.
⩥ Epidermis Function.
Answer: Provides protection and reduces water loss.
⩥ Dermis.
Answer: Deep layer of the skin composed of connective tissue.
⩥ Dermis Function.
Answer: Provides structural strength to the skin.
⩥ Subcutaneous Tissue (Hypodermis).
Answer: Loose connective tissue that connects skin to underlying
structures; not technically part of the skin.
⩥ Epidermis Blood Supply.
Answer: Avascular; nourished by diffusion from capillaries of the
papillary layer of the dermis.
⩥ Epidermis Structure.
Answer: Composed of epithelial cells arranged into layers or strata;
separated from the dermis by a basement membrane.
, ⩥ Keratinocytes.
Answer: Most abundant cells in the epidermis; produce keratin for
strength.
⩥ Melanocytes.
Answer: Epidermal cells that contribute to skin color by producing
melanin and transferring it to keratinocytes.
⩥ Melanocyte Count.
Answer: All people have the exact same number of melanocytes
regardless of skin color.
⩥ Langerhans Cells.
Answer: Epidermal cells that are part of the immune system.
⩥ Merkel Cells.
Answer: Epidermal cells that detect light touch and superficial pressure.
⩥ Keratinization.
Answer: Process where cells move outward through the layers, fill with
keratin, die, resist abrasion, and form a permeability layer.
