tissues

covers surfaces....covers the ezxternal body surface, lines the cavities and tubules.

marks are insides off from our outsides

glands such as endocrine and exocrine glands are made from

this tissue functions as protection, absorption, filtration, ecretion, secretion and sensory reception

the membranes always have one free surface called apical surface and typically that surface is significantly different from the basal surface

the outside surface of epithelial tissue

the inside surface of epithelium tissue

the cells in this tissue fit closely together to form a membrane

sheets of cells  and are bound together by specialized junctions

supported by connective tissue. the cells are attached by an adhesive basement membrane

is an amorphous material secreted partly by the epithelial cells (basal lamina) and connective tissue cells (reticular lamina) that  lie adjacent to each other

this tissue has no blood supply of their own (are avascular) but insteaddepend on diffusion of nutrients from the underlying connective tissue.

T or F Glandular epithelia is vary vassular
True False

The lining epithelial are classified  according to what two criteria

consisiting of one layer of cells attached to the basement membrane

consisting of tow or more layers of cells

The general types of epithelia based on shapes

scalelike shape

column shaped

cube like

simple columnar epithelium (one layer of cells), but because its cells vary in height and the nuclei lie at differnet levels above the basement membranem it gives you a false apperence of being stratified. This is often ciliated.

is a rather peculiar stratified squamous epithelium formed of rounded or plump cells with the ability to slide over one another to allow the organ to be stretched

found only in the urinary system organs subjected to periodic distension such as the bladder. flatter like squamous when stretched but when tension is released they are roung and plump

ductless glands

hormones are released into extracellular fluid, from which they enter the blood or the lymphatic vessels that weave through the glands

glands that retain their ducts

secretions empty through their ducts

sweat and oil glands

liver and pancreas secrete through

flattened, single layer cells. central nuclei and sparse cytoplasm, the simplest of epithelium

allows passage of materials by diffusion and filtration in sites where protection is not important, secretes lubricating substances in serousae

this tissue is located in kidney glomeruli, air sacs of lungs, lining of heart and blood vessels, serosae membrane of ventral portion

single large cubelike cells, with large sperical nuclei

found in kidney ducts, secretory portions of small glands and ovary surface

single layer of tall cells with round to oval nuclei, some cells bear cilia, layer amay contain mucus secreting unicellular glands ( globlet cells)

absorption, secrtion of mucus enzymes and other substances, ciliated type propaels mucus or reproductive cells by cillary action.

located in stomach to anal canal, gallblader and excretory ducts of some glands, ciilated variey lines small bronchi, uterine tubes and some regions of the unterous

single layer of cells of differing heights, some not reaching the free surface, suclei seen at difernet levels, may contain mucus secreting cells and bear cilia

secretion particularly of mucus, propulsion of mucus by ciliary action

ciliated type lines upper respitory area

non ciliated types, lines males sperm carrying ducts and ducts of large glands

thick membrane composed of several cell layers, basal cells are cuboidal or columnar and metabolically active, surfacecells are flattened(squamous) in the keratinized type the surface cells are full of keratin and dead, basal cell are activein superficial layers

form the skin

lines mouth and uterus

two layers of cubiodal cells

function - protection

found in largest ducts of sweat glands, mammary glands and salivary glands

several layers of basal cells usually cuboidal, superficial cells elongated and columnar

functions - protection and secretion

found in small amounts of male urethra and in large ducts of some glands

resembles both stratified squamous and stratified cuboidal, basal cells cuboidal or columnar, surface cells some degree of organ stretch

a tissue found in all parts of the body as discrete structures of as part of various body organs. Its the most abundant and widely distributed of the tissue types

primary function of this tissue is to protect, support, and bind together other tissues of the body

bones, ligaments, and tendons are examples of what type of tissue

tendons and ligamenst are what type of connective tissue

also known as osseous tissue

is soft  packaging material that cushions and protects body organs

adipose

looks like bubbles with few nuclei

looks like thick yarn, dark strings and scatured spotes

looks like cells jumbled together, with thick looking vain branches

looks like waves with long skinny nucleis that goes with wave

looks like a bunch of curely strings
