Epidermis - Answer Thin, outer layer of skin.
Dermis - A thicker, inner layer of skin.
ANSWER: Subcutaneous fat tissue Layers of loose connective tissue
Deeper tissues - answer muscle, tendons, ligaments, joint capsule, and bone.
Basement Membrane Zone (BMZ) - Answer Anchors the epidermis to the
dermis, causing blister formation. Disrupted during wound healing and must be
repaired.
Lamina Lucida - Answer Zone in the BMZ (electron-translucent zone).
Lamina Densa - Answer Layer in the BMZ (Electron-Dense Zone)
BMZ's major proteins include fibronectin, laminin, type IV collagen, and
heparin sulphate proteoglycan.
Stratum Basale: ANSWER The epidermal layer is one cell thick. The only la
yer of epidermis in which cells undergo mitosis forms the BMZ.
The stratum spinosum is a layer of the epidermis made up of multiple rows of
adult keratinocytes that seem spiny when viewed under a microscope.
, The stratum granulosum is the epidermal layer that has 3-5 flattened cell rows
with increasing keratin concentrations.
Stratus Lucidum: ANSWER Layer of the epidermis In thick skin, dead skin
cells form a thin, transparent layer.
Stratum Corneum - Answer The epidermis layer is made up of dead cells that
shed easily, contains keratin, acts as an environmental barrier, and limits
transepidermal water loss.
Epidermal cells include keratinocytes, Langerhans' cells, melanocytes, and
Merkel's cells.
Keratinocytes: ANSWER Keratin, the primary component of hair, skin, and
nails, is produced by the skin and is responsible for its toughness.
Langerhans Cells - ANSWER Help protect the body against infections by
recognising allergens and boosting immunity.
Melanocytes are responsible for creating melanin.
Merkel's Cells - ANSWER Mechanoreceptors that offer information on light
and rough sensation
Epidermal Appendages: ANSWER Sebaceous glands, hair follicles, sweat
glands (eccrine and apocrine), and nails.
