| tissue types | epithelial, connective, muscle, nervous |
| epithelial tissue | covers organs, lines cavities,opens to outside or open space internally |
| epithelial tissue | functions in protection, absorption, secretion,excretion, filtration |
| simple squamous | single, flattened cell, tight fit; diffusion, filtration |
| simple cuboidal | single, square shape nuclei, cover ovaries,kidney, ducts, salivary |
| simple cuboidal | functions in secretion, absorption |
| simple columnar | single, elongated, nuclei at basement;,lines uterus,stomach,intestines |
| simple columnar | tissue thick, protects tissues, microvilli, goblet cells secret mucus |
| glandular epithelium | 2, cells that secrete substances into ducts or body fluids |
| glandular epithelium | exocrine, endocrine; for secretion |
| endocrine | secrete products into body fluids or blood, ductless gland |
| exocrine | secrete products into ducts that open to internal or exteranl surface |
| merocrine | type of exocrine secretion, release fluid,(salivary gland), most common |
| apocrine | type of exocrine secretion, lose small portion of cells with secretion(mammory gland) |
| holocrine | type of exocrine secretion, release entire cells,(sebaceous gland) |
| serous fluid | watery, high concentration of enzymes; from inner linings |
| mucus | thicker, glycoprotein, from inner linings(digestive, respiratory) |
| carcinoma | cancer starts in epithellium, most begin on surfaces that contact external environment |
| connective tissue | weighs most, binds structures, support, framework |
| fibroblast | type of fixed cell, most common, star shaped |
| machrophage | type of cell, (histocyte), in WBC, fight infection |
| mast | type of cell, large, near blood vessels, release Heparin, Histamine |
| type of cells | fibroblast, machrophage, mast |
| type of fibers | collagenous, elastic, reticular |
| collagenous fiber | protein collagen, high tensile strength, hold stuctures together |
| ligaments | hold bone to bone |
| tendons | hold muscle to bone |
| elastic fiber | protein elastin, weaker than collagenous, very elastic |
| reticular fiber | very thin,highly branched, form delicate networks, collagenous fibers |
| types of connective tissue | adipose, cartilage, bone, blood |
| adipose tissue | fat, under skin, between muscles, behind eyes, abd., heart |
| adipose functions | insulation, protection, stores energy |
| cartilage | rigid, support, framework, attachments, protection |
| cartilage | heals slowly, chondrocytes(cartilage cells) |
| types of cartilage | hyaline, elastic, fibrocartilage |
| bone | most rigid, hardness due to mineral salts, more collagen |
| bone functions | support, protection, attachment, formation blood cells |
| osteocyte | bone cell |
| bone | very active tissue, injured bone heals rapidly |
| blood | RBC, WBC, platelets |
| plasma | fluid with RBC, WBC and platelets |
| RBC | transport gases; entirely in blood vessels |
| WBC | fight infection |
| platelets | involved in blood clotting |
| muslce tissue | contractile, can shorten and thicken to cause movement |
| types of muscle tissue | skeletal, smooth, cardiac |
| skeletal muscle | voluntary, striated, attach muscle to bone; many nuclei |
| smooth muscle | lacks striations, involuntary; lines walls of stomach,intestine,bladder,uterus, 1nucleus |
| cardiac muscle | only in heart, striated end to end; 1nucleus, involuntary |
| intercalated disc | where touches another cell; only in cardiac tissue |
| nervous tissue | in brain, spinal cord, peripheral nerves |
| nervous tissue function | coordination of body, no reproduction of cells |
| neurons | nerve cells |
