Chapter 4 tissues

Epithelial tissues

lines hollow organs

connective tissues

protects ans supports and blinds organs ex(bone, blood, cartilage)

What tissue would fat be

connective

muscular tisssue

generates physical force to make the body move

nervous tissue

detects changes in the body and responds by generating naive impulses

epithelia tissue

cells arranged in continuous sheets

true or false epithelial tissue can be single or multiple layered

true

single layer

single

multiple layer

stratified

in epithelial tissues cells are ____ packed together

closely

epithelial tissues are found at

a boundary betweenween two different environments

epithelial will always

have a free surface somewhere that has space on top of it

two types of epithelial

cover and Line, glandular co

covering And lining

covers outer surfaces, lines inner surfaces

glandular epithelium

forms most glands of the body to produce some sort of product , sweat gland, oil glands

general functions of epithelium

protection of underlying tissues, secretion, absorption, diffusion, filtration, sensory

special features of epithelial

abundance of cells, specialized contact pointsanchored to a basement membrane, polarity(basal, apical), support by connective tissue (basement membrane), avascular, high regeneration, nervous innervation

apical surface

faces body surface

basal surface

opposite of apical surface, adheres to basement membrane

because epithelial tissue is a vascular it is dependent on

diffusion

Regeneration results from

high motif activity

True or false classify epithelial first shape of cells, second arrangement of cell layers

false vice versa

cubodial

square

squamous

flat

columnar

like a column, longer than flat

you name the cell shape on the most

apical surface

simple squamous

one layer flat cells (thinnest layer possible), allows passage of materials by diffusion and filtration,

What is a component of all tissue cells

cells and extracellular matrix

epithelial tissues cover body surfaces and lines hollow organs aswell as `

body cavities and ducts. They also form glands and protect underlying structures.

connective tissue binds organs aswell as

store energy as fat

muscular tissue generates physical force needed to make body structures and generate

body heat

simple

1 cell layer

cuboidial

square

a simple cubodial epithelium function is

secretion and absorption (part of the gland produces substance

) ex: sweat

simple cubodial epithelium can be found in

Kidney tubules, ducts and secretory portions of small glands, ovary surface

epithelial cell always faces

free surface

hollow space

lumen

What cell is this

simple cubodial epithelium

What cell is this

simple columnar epithelium

simple columnar epithelium is described as

a single layer of tall cells with round oval nuclei, some cells bear cilia, layer may contain mucus secreting unicellular glands

simple columnar epithelial cilia microtubules are at the

apical surface of the epithelial

simp0le columnar epithelium function

absorption, secretion of mucus, enzymes, and other substances, cilliated thype propels mucus by cilliary action

where do noncililated simple columnar epithelium reside

lines most of the digestive tract, gallblaffer and excretory ducts of some glands

where do cilliated simple columnar epithelium reside

small bronchi, uterine tubes, and some regions of the uterus

what are goblet cells

specialized epithelial cells that produce mucous

cilia is often associated with

mucous

pseudostratified columnar epithelium description

single layer of cells differing heights, some not reaching the free surface, nuclei seen at different levels, may contain goblet cells and bear cilia

pseudostratified columnar epithelium function

secretion of mucus, propulsion of mucus by ciliary action
