blue skin

yellow skin

red skin

white skin

consists of skin and accessory organs. is two layers: epidermis and dermis

composed of 5 strata: corneum, lucidum, granulosum, spinosum, basale

4-6 weeks

25-30 layers of dead cells

only present in thick skin

3-5 layers of cells; living dead transition zone; Keratohyalin; Lamellar granules

8-10 layers; keratin intermediate filaments; cells joined by desmosomes;

from which all others are derived from

keratinocytes, langerhan cells, melanocytes, merkel cells,

90% epidermal cells; produces keratin

protects from heat, abrasion, microbes, chemicals

only in living parts of the epidermis; intraepidermal microphage; Phagocytosis; stratum spinosum

8% of epidermal cells; produce melanin; stratum basale

detect touch sensations; stratum basale

gives rise to finger prints; inc surface area of epidermis; inc contact b/w dermis + epidermis; epidermal peg supported by dermal papilla (see image in notes)

yellow-red / brown-black pigment; responsible for skin and hair colour

no melanin produced

aggregation of melanin/melanocytes

cancerous mole

location of BVs, nerves, hair follicles, and skin glands; contains collagen and elastic fibres that provide support for the skin; divided into papillary and reticular regions

sebaceous, apocrine, eccrine, ceruminous

responsible for the oils in our skin

responsible for creating sweat

responsible for creating sweat; regulated by the SNS

responsible for the waxy

thermo-regulation, blood reservoir, protection for the environment, cutaneous sensations, excretion and absorption, synthesis of vitamin D (make sure to know how to explain all of them)

black-brown form of melanin

red-yellow form of melanin

connective tissue is the most ______ tissue by weight

asymmetrical, border uneve, colours (two or more), diametr >6mm, elivated/evolving

superficial dermis region

deep dermis region

also known as the subcutaneous fluid

a type of cell death in which the cell uses specialized cellular machinery to kill itself; occurs in stratum granulosum
