Anatomy: Integumentary System
Cards in this deck (46)
- 1- Largest System of the body - 16% of body weight - 1.5 to 2m^2 in areaIntegument/Integumentary System
- 22 parts of the Integumentary systemCutaneous Membrane
Accessory Structures - 3Part of the Integumentary system that contains the Epidermis & DermisCutaneous Membrane
- 4- Part of the Integumentary system that originated in the dermis - Extend through the epidermis to the skin surfaceAccessory Structures
- 5- Loose connective tissue - site of subcutaneous injections using hypodermic needles - Is connected to the reticular layer of integument by connective tissue fibersSubcutaneous layer (Hypodermis)
- 6Another term for Subcutaneous layer apart from HypodermisSuperficial Fascia
- 7An avascular stratified squamous epithelium where nutrients diffuse from capillaries in the dermisEpidermis
- 8Covers most of the body & has 4 layers of keratinocytesThin Skin
- 9Covers the palms of the hand and soles of the feet & has 5 keratinocytesThick Skin
- 105 strata of keratinocytes in the thick skinStratum: Germinativum
spinosum
granulosum
lucidum
corneum - 11- Has many germinative cells or basal cells - Attached to basal lamina by hemidesmosomes - Forms a strong bond between epidermis and dermisStratum Germinativum
- 12- The “spiny layer”: - Produced by division of stratum germinativum - Eight to ten layers of keratinocytes bound by desmosomesStratum Spinosum
- 13The “grainy layer” Stops dividing, starts producingStratum Granulosum
- 14The “clear layer”: Found only in thick skin Covers stratum granulosum Stratum Lucidum
- 15The “Horn Layer” - Exposed surface of skin - 15 to 30 layers of keratinized cells - Water resistant - Shed and replaced every 2 weeksStratum Corneum
- 16The formation of a layer of dead, protective cells filled with keratinKeratinization
- 17Three skin pigmentsMelanin
Carotene
Hemoglobin - 18- protects skin from sun damage - In granules it passes from melanocytes to keratinocytes in stratum basale - digested by lysosomesMelanin
- 19Causes DNA mutations and burns that lead to cancer and wrinklesUltraviolet (UV) radiation
- 20- Bluish skin tint - Caused by severe reduction in blood flow or oxygenationCyanosis
- 21Organs that converts Vitamin D3 into calcitriolLiver
Kidney - 22produced by epidermal cells in the presence of UV radiationCholecalciferol (Vitamin D3)
- 23it aids absorption of calcium and phosphorusCalcitriol
- 24It can cause RicketsInsufficient Vitamin D3
- 25Is located between epidermis and subcutaneous layer Anchors epidermal accessory structures (hair follicles, sweat glandsDermis
- 26Component of Dermis that consists of areolar tissuePapillary Layer
- 27Component of Dermis that consists of dense irregular connective tissueReticular Layer
- 28Derived from epidermis but extend into dermisSkin appendages
- 29Body parts that are not covered with hairPalms
Soles
Lips
Portions of external genitalia - 30Produced by melanocytes at the hair papillaHair Color
- 31Parts of HairRoot
Shaft - 32Three concentric layers of HairMedulla
Cortex
Cuticle - 33Types of hairVellus
Intermediate
Terminal
- 34contains lipids and other ingredients lubricates and protects the epidermis inhibits bacteriaSebum
- 35It Contains the sebaceous & sweat glands (Watery Secretion)Exocrine Glands in the skin
- 36Simple branched alveolar glands:associated with hair folliclesSebaceous (Oil) Glands
- 37Sweat gland found in armpits, around nipples, and groin Secrete products into hair follicles Surrounded by myoepithelial cells: In response to hormonal or nervous signalApocrine Sweat Glands
- 38Sweat gland that is widely distributed on body surface Especially on palms and soles Discharge directly onto skin surfaceMerocrine (Eccrine) Sweat Glands
- 39protect fingers and toes Made of dead cells packed with keratin Metabolic disorders can change its structureNails
- 40Threat to life Catastrophic loss of body fluids Dehydration and fatal circulatory shock InfectionBurn
- 41*Types of burn epidermis: rednessFirst Degree Burn
- 42*Types of burn epidermis and upper dermis: blisterSecond Degree Burn
- 43*Types of Burn (full thickness, destroying epidermis, dermis, often part of hypodermis)Third Degree Burn
- 44Disorders of the integumentary systemBurns
Infections
Skin Cancer - 45Most common type of skin cancer considered malignant b/c causes significant destruction and disfigurement of surrounding tissuesBasal cell carcinoma
- 46Malignant tumor of melanocytes Less common skin cancer but causes majority of skin cancer related deathsMelanoma
