Unit 2 Flash Cards

Groups of similar cell and cell products

work together to perform a certain function or make a specific structure

Four major categories of tissues or types of tissue

study of microscopic anatomy

How many different cell types are there?

Forms the lining of the body cavities, covers body surfaces and glandular tissues

one or more layers of closely adhering cells

Tissue that sits on basement of membrane

Extra cellular material so thin it is not visible

tissue cut along the longest direction of an organ

tissue cut perpendicular to the length of an organ

tissue cut at an angle between a cross and longitudinal section

function of epithelial tissues

Made primarily of epithelial tissue

-contains one layer of cells'
-names by shape of cells

-more than one layer of cells
-names for shape of cells of the apical cells

-single row of flat cells
-Allows rapid diffusion of substances; secretes serous fluid
-found in alveoli of the lung, glomeruli in the kidney, endothelium in blood vessels and serosa

mucus producing cell scattered throughout the pseudostatified ciliated conlumnur epthelium

-single row of cube shaped cells, often with microvili
-involved in absorption and secretion in some areas and produces mucus in other areas such as respitory tract
-liver, thyroid, salivery and other glands bronchials and most kidney tubules

-single row of tall, narrow cells
-vertically oriented, oval nucleic in basal half of cells
-absorption and secretion; and secrestion of mucus
-inner linning of gi tract, uterus, kidney and uterine tubes

-lines passage of repitory and reproductive tracts
-respitory passages mucus covered linning are sticky and trap particles of dust and micro organism that enter with the air
-cillia move the mucus and particles upward and out of airways
-cillia aid the movement of sex cells from one region to another

-composed of more that one layer of cells and named for shape of surface or apical cells
-Deepest cells sit on basement membrane

-multi layerd epithelium covered with layer of compact, dead squamus cells packed with protein keraiten
-slows down water loss and prevents penetration of organism
-forms epdermal layer of skin

-multilayered epithelium that lacks surface layer of dead cells forming abrasion-resistant, moist slipery layer
-found on tough, oral mucose, esophugus and adult vagina

-two or more layers of cells, surface cells square
-secretes sweat or ovarian hormones, produces sperm
-found in sweat gland ducts; overain follicles and sminiferous tubules

-multilayerd epithelium with rounded surface cells that flatten when tissue is strectched
-stretched to allow filling or urinary tract
-found in urinary tract-kidney, ureter,bladder
