| 6195969715 | Dermis | Areolar CT & Dense Irregular CT | 1 | |
| 6195975117 | Epidermis Cells | Keratinocytes, Melanocytes, Langerhans'/Dendritic cells, Merkel Cells | 2 | |
| 6195980045 | Keratinocytes | Produce keratin | 3 | |
| 6195981596 | Melanocytes | synthesize the pigment MELANIN | 4 | |
| 6195988206 | Langerhans'/ Dendritic Cells | arise from bone marrow and migrate to the epidermis to ingest foreign substances. they are key activators of our immune system | 5 | |
| 6196097707 | Layers of the Epidermis | Stratum basale, Stratus spinosum, Stratus granulosum, Stratum lucidum, Stratum corneum | 6 | |
| 6196129612 | Stratum basale (Basal layer) | deepest layer; attached to underlying dermis; resembles corrugated cardboard; consists of a single row of stem cells; rep. longest keratinocytes; aka stratum germinative | 7 | |
| 6196168023 | Stratum spinosum (Prickly layer) | several cell layers thicks; cells contain a weblike system of intermediate filaments of bundles of pre-keratin filaments; keratinocytes have spines (prickle cells) | 8 | |
| 6196196576 | Stratum granulosum (Granular layer) | 1-5 cell layers in which keratinocyte appearance changes drastically & the process of keratinization begins | 9 | |
| 6196214503 | Stratum lucidum (clear layer) | visible only in thick skin; views as a thin translucent band just above the stratum granulosum through a light microscope; consists of 2-3 rows of clear, flat, dead keratinocytes with indistinct boundaries | 10 | |
| 6196279584 | Stratum corner (horny layer) | most superficial; consists of flattened, enucleated cells ; broad zone 20-30 cell layers thick accounting for up to three-quarters of the epidermal thickness; provides a durable overcoat for the body, protecting deeper cells from the hostile external environment (air) and from water loss, and rendering the body relatively insensitive to biological, chemical and physical assaults | 11 | |
| 6196313557 | Merkel Cells (Tactile) | present at the epidermal junction; shaped like a spiky hemisphere; each cell is intimately associated with a dislike sensory nerve ending; functions as a SENSORY RECEPTOR for touch | 12 | |
| 6196327615 | Dermis Layers (Dermal Layers) | Papillary Layer & Reticular Layer | 13 | |
| 6196357265 | Papillary Layer | Layer of the Dermis; Made up of Areolar CT; Contains dermal papilla (piglike protections that indent the over lying epidermis) and meissners corpuscles (touch receptors) | 14 | |
| 6196391538 | Reticular Layer | Layer of the Dermis; Made up of Dense Irregular CT; Contains Pacinian (lamellar) corpuscles (large receptors) and arrectors pili muscle (bundle of smooth muscle cells) | 15 | |
| 6196440346 | Cutaneous Glands | Sudoriferous glands & Sebaceouss glands | 16 | |
| 6196447239 | Suboriferous glands | produce sweat; over entire skin surface (ex. nipples & some external genitalia) contains: eccrine recreating glands & apocrine glands with fatty substances & proteins | 17 | |
| 6196464103 | Sebaceous glands | produce sebum (oil); simple branched alveolar glands all over the body (ex. palms & soles) | 18 | |
| 6196473415 | Tuberosity | Large rounded projection; may be roughened | 19 | |
| 6196699402 | Crest | Narrow ridge of bone; usually prominent | 20 | |
| 6196703445 | Trochanter | Very large, blunt, irregularly shaped process | 21 | |
| 6196705901 | Line | Narrow ridge of bone; less prominent than crest | 22 | |
| 6196708345 | Tubercle | Small rounded projection or process | 23 | |
| 6196709974 | Epicondyle | Raised area on or above a condyle | 24 | |
| 6196711914 | Spine | Sharp or slender, often pointed projection | 25 | |
| 6196714379 | Process | Any bone prominence | 26 | |
| 6196716564 | Head | Bony expansion carried on narrow neck | 27 | |
| 6196718192 | Facet | Smooth, nearly flat articular surface | 28 | |
| 6196719815 | Condyle | Rounded articular projection | 29 | |
| 6196722369 | Ramus | Armlike bar of bone | 30 | |
| 6196722370 | Sinuses | Cavity within a bone; filled with air & lines with mucous membrane | 31 | |
| 6196727067 | Meatus | Canal-like passageway | 32 | |
| 6196730098 | Fossa | Shallow, basin-life depression in a bone; often serving as an articular surface | 33 | |
| 6196733821 | Groove | Furrow | 34 | |
