Chapter 5 Integumentary

90% of cells in the epidermis, which produce a tough, fibrous, protective protein

• Keratinocyte

• Dendritic cell

• Melanocyte

• Tactile epithelial cell

Layer of the epidermis found only in thick skin

• Stratum corneum

• Stratum lucidum

• Stratum granulosum

• Stratum spinosum

Assembles keratin intermediate filaments into keratin

• Keratinase

• Keratohyalin Granules

• Keratinocyte

• Stratum granulosum

Composed of connective tissue containing collagen and elastic fibers

• Epidermis

• Dermis

• Subcutaneous

These secrete an oily substance which prevents dehydration of hair and skin and inhibits certain bacterial growth

• Sudoriferous Glands

• Eccrine Sweat Glands

• Sebaceous Glands

• Apocrine Sweat Glands

25-30 layers of flat, dead keratinocytes that are continuously shed

• Stratum corneum

• Stratum granulosum

• Stratum spinosum

• Stratum basale

Site of continuous cell division which produces all of the layers above it

• Stratum corneum

• Stratum granulosum

• Stratum spinosum

• Stratum basale

The order of deep wound healing

• Inflammatory, Proliferation, Migratory, Maturation

• Inflammatory, Migratory, Proliferation, Maturation

• Migratory, Inflammatory, Proliferation, Maturation

• Inflammatory, Migratory, Maturation, Proliferation

Hard keratinized epidermal cells located over the dorsal surfaces of the most distal ends of the extremities

• Hair

• Stratum corneum

• Keratinocytes

• Nails

The predominant sweat gland which secretes mostly water

• Apocrine

• Sebaceous

• Ceruminous

• Eccrine
