Cards in this deck (67)
- 1what are the 4 types of tissueepithelial
connective
muscular
nervous - 2which type of tissue is most abudantconnective tissue
- 3where is epithelial tissue foundexterior/superficial skin
lines hollow organs
lines hollow passages exiting the body - 4what 2 characteristics differentiate connective tissue types?-type of fibers
-abundance of fibers vs. matrix - 5What are the classes of connective tissue?-Bone
-Cartilage
-connective tissue proper
-Blood - 6What are the functional differences for elastic and collagen fibers in CT- elastic provides strength and stretch
ie: lungs, skin, blood vessels
-collagen provides strength and structure
ie: bone, cartilage, tendons, ligaments - 7what are the types of fibers found in connective tissue?-elastic
-collagen
-reticular - 8what are reticular fibers?-found in connective tissue
-fine collagen fibers
-form a supportive mesh
-support soft tissues and organs - 9What are the types of muscular connective tissue-skeletal
-smooth
-cardiac - 10What is the purpose of muscular CTmotion
- 11How does muscular connective tissue produce motion-action potentials
-contractility
-extensibility
-elasticity
-excitability - 12What are the 3 defining characteristics of skeletal muscular connective tissue-attached to bone
-striated
-voluntary movement - 13What are the defining characteristics of cardiac muscular connective tissue-striated
-involuntary contractions
-only found in heart - 14Where is smooth muscle CT found?-found in walls of hollow internal organs
-Uterus, stomach, bladder, blood vessels - 15What is visceral muscle tissueSmooth muscle connective tissue
- 16What can smooth muscle CT do-constrict / contract
-provides involuntary motion of systems
ie: dilation of blood vessels
propulsion of food thru GI tract
contracts urinary bladder - 17What are the visual characteristics of smooth muscle connective tissue-non-striated
-spindle shaped
-elongated nucleus - 18What is the largest organ of the bodyskin
- 19What is the function of skin-sensitivity to touch, pain, temperature, pressure
-protects against pathogenic organisms
-protects against trauma
-regulates body temp (sweat)
-stores nutrients
-synthesis of vt.D
-keeps good molecules in and bad molecules out - 20What 2 tissues compose skin-epidermis
-dermis - 21What type of tissue is the epidermisstratified squamous epithelium
- 22Can epidermis keratinizeyes
- 23How does the epidermis maintain its constant thickness-growth and shedding
-desquamation - 24why does skin not bleed from light scratches?the epidermis is avascular, it lacks its own blood supply
- 25What are the 2 regions of the dermis?papillary layer
reticular layer - 26Meissners Corpusclesfree nerve endings & touch receptors
- 27which region of the dermis is the upper region?papillary layer
- 28which region of the dermis is the lower region?reticular layer
- 29what are the contents of the reticular layer?-blood vessels
-sweat glands
-oil glands
-deep pressure receptors aka
Pacinian Corpuscles - 30what are the contents of the papillary layer?-dermal papillae
-nerve endings & touch receptors
(meissners corpuscles) - 31what is subcutaneous tissue in reference to skin?-underlies the dermis
-not part of the skin
-anchors the skin to other organs
-shock absorber - 32What tissue insulates deeper tissues from exterior temperature changes?subcutaneous tissue
- 33what are the 3 types of glands found in the dermis?-eccrine sweat gland
-apocrine sweat gland
-sebaceous gland - 34label the glandsA. sebaceous
B. eccrine sweat
C. apocrine sweat - 35explain pseudostratificationlayers that appear to be stratified (multi layer) but are actually simple (one layer)
- 36Describe the 3 shapes of cells-columnar: tall
-cuboidal: cube
-squamous: flat - 37why is transitional epithelium unique?it changes in appearance based on tension, it will appear differently with different amounts of tension
- 38where is transitional epithelium foundUrinary bladder
- 39describe the squamous cell shapeflattened, like a fried egg (nucleus is yolk)
- 40—simple squamous epithelium
- 41—stratified squamous epithelium
- 42—simple cuboidal epithelium
- 43—stratified cuboidal epithelium
- 44—simple columnar epithelium
- 45—stratified columnar epithelium
- 46—pseduostratified ciliated columnar epithelium
- 47what is the connective tissue's extracellular matrixglycosaminoglycans +hyaluronic acid
- 48—loose areolar connective tissue
- 49—Adipose tissue
- 50—Dense regular connective tissue
- 51—Dense regular connective tissue
- 52—Dense irregular connective tissue
- 53—Hyaline cartilage
- 54—Elastic cartilage
- 55—fibrocartilage
- 56—compact bone
- 57—spongy bone
- 58—spongy bone
- 59—blood
- 60—skeletal muscle
- 61—smooth muscle
- 62—cardiac muscle
- 63—nervous tissue
- 64first degree burn characteristicsredness, swelling, pain
epidermal damage only - 65second degree burn characteristicsepidermal and upper dermal damaged
blisters - 66third degree burn characteristicsfull thickness burn
no pain
skin is cherry red, grey-white, or black - 67—transitional epithelium
