Term
epithelial tissue functions
Definition
protection, absorption, excretion, filtration, secretion and sensory reception
Term
epithelia tissue characteristics
Definition
polarity (apical/basal), avascularity, basement membrane (connective tissue base), regenerative
Term
simple squamous (functions, description, location)
Definition
filtration and exchange of substances. air sacs of lungs and blood vessel lining. thin permeable
Term
simple cuboidal epithelium (functions, description, location)
Definition
secretion and absorption. glands.
Term
simple columnar epithelium (functions, description, location)
Definition
secretion, absorption. has microvilli and goblet cells. digestive tract.
Term
pseudostratified columnar (functions, description, location)
Definition
contains many goblet cells. lines most upper respiratory passages
Term
stratified squamous epithelium (functions, description, location)
Definition
apical layer-simple squamous. adapted to resist abrasion. lines esophagus, vagina. keratinized version forms skin epidermis
Term
stratified cudoial epithelium (functions, description, location)
Definition
rare. male urethra and transitional places between other epithelial types
Term
transitional epithelium (functions, description, location)
Definition
modified stratified squamous. responds to stretch. urinary system organs.
Term
gland classification
Definition
exocrine/endocrine. unicellular/multicellular. simple/compound. tubular/avelar/tubuloaveolar. Merocrine (secret by exocytosis)/Holocrine (secrete via rupture).
Term
connective tissue functions
Definition
support, protection, binding, insulation, transportation
Term
connective tissue characteristics
Definition
all from embryonic mesenchyme. matrix. varying vascularization
Term
connective tissue structure
Definition
extracellular matrix (ground substance [cell adhesion proteins, proteoglycans] and fibers [collagen, elastic, reticular]). primary cell type (fibroblast, chondroblast, osteoblast, hematopoietic)
Term
connective tissue proper - loose - areolar (functions, description, location)
Definition
stores nutrients as fat. holds body fluids. defends infections. contains collagen, elastic, and reticular fibers. forms packaging around organs
Term
connective tissue proper - loose - adipose (functions, description, location)
Definition
hold many nutrients. 90% fat. insulates and protects body organs. energy reserves for certain hard-working organs.
Term
connective tissue proper - loose - reticular (functions, description, location)
Definition
 like areolar but only reticular cells within a reticular fiber network in soft ground substance. soft internal skeleton. bone marrow and spleen.
Term
connective tissue proper - dense - regular (functions, description, location)
Definition
parallel bundles of collagen fibers. few cells and ground substance. tendons, ligaments, aponeruoses. fibers are dominant element
Term
connective tissue proper - dense - irregular (functions, description, location)
Definition
fibers arranged irregularly. resists tension from different directions. dermis of skin and organ capsules
Term
hyaline cartilage (functions, description, location)
Definition
firm ground substance containing collagen fibers. resists compression.bone surfaces, trachea.
Term
elastic cartilage (functions, description, location)
Definition
elastic fibers dominate. flexible support. ear and epigottis.
Term
fibrocartilage (functions, description, location)
Definition
corse parallel collagen fibers. support with compressibility. intervertrbral discs and knee cartilages.
Term
bone (osseous tissue) (functions, description, location)
Definition
hard, collagen-containg matrix with calcium salts. cavities for fat storage and blood synthesis. skeleton.
Term
blood (functions, description, location)
Definition
blood cells (red and white) and plasma matrix. carried nutrients, waste, respiratory gases, etc.
Term
nervous tissue (functions, description, location)
Definition
composed of neurons and supporting cells. brain, spinal cord, nerves. receive and transmit impulses. react to stimuli.
Term
skeletal muscle tissue (functions, description, location)
Definition
attached to bone. movement. cylindrical and striated. MUSCLE FIBERS.
Term
cardiac muscle tissue (functions, description, location)
Definition
walls of heart. branched. uninucleate. contracts to propel blood. inercalated disks between branches.
Term
smooth muscle tissue (functions, description, location)
Definition
walls of hallow organs. involuntary. squeezes substances through with contraction/relaxation. no striations
Term
epithelial membranes
Definition
cutaneous membrane (skin), mucus membrane (lines body cavities, stratified or simple columnar), serous membrane (lines body cavities [parietal - outer, visceral - internal] simple squamous above areolar tissue)
Term
tissue trama reaction
Definition
dilation of blood vessels (increase permeability), redness, heat, swelling, pain.
Term
tissue repair
Definition
blood clot replaced with granulation tissue. regeneration of cells via mitosis or fibrosis (fibers grow and form scar tissue). surface epithelial is pushed to the apical surface and scab falls off. regenerates with scar tissue underneath.
Term
developmental
Definition
ectoderm (nervous tissue and epithelial), mesoderm (muscle and connective tissue and epithelium), endoderm (mucosae and epithelial)
