   Adipose Connective tissue (FAT-think LONG TERM __)
little extracellular matrix (fat cells) function in packing material, thermal insulator, energy storage located around kidneys and mammary glands
4 types of tissue and what they do
epithelia-covers & lines surfaces, Connective-bind & support body parts, Muscle-movement, and nervous-detects changes & transmit info

Dense Collagenous Connective tissue

think ligament 

matrix composed of collagn fibers (inthe dermis) Function: ability to withstand pulling forces. located in tendons ligaments found in the dermis of skin.

what divides rapidly on the basement membrane?

and ____is not in contact with other cells 

basile cells

free surface 

where are simple columnar ET found?

think column think long lines.  

the nuclei are located near the base of the cells. forms the lining of the stomach and intestine/ sensroy reception nose, ears tast. 

where is simple cuboidal ET found?


glands and kidney tubules as well as in ducts and glands.

which body cavity is lined with serous membrane? and are they open or closed?

what is serous fulid? 

Pleural (lungs), peritoneum (addominal cavity & covers organs) and pericardium which surrounds the heart       lines closed cavities

a lubricant 

many osteocytes it provides strength and support and protects located in all bones of the body ex cancellous and compact bone
characteristics of CT
Few cells, non living matrix, found in all body parts, BINDS body components together VASCULAR(blood vessels) and FIBROBLASTS -secretes fiber.
characteristics of epithelial tissue, how are they arranged, functions,
tightly packed cells, arranged in layers. free surface & basement membrane below. To protect absorb, sensation, secretion. High rate of cell division healing. rely on diffusio-getting rid of bad stuff
classifications of connective tissue 6 types (2 branch off into another group)

Loose or areolar                                       &n

classifications of epithelial tissue (layers) and the 4 shapes
simple (one layer), stratified(>1layer) Shapes: Squamous, cuboidal, columnar (tall & thin) and transitional which has no particular shape
connective tissue blood
blood cells& fluid matrix. It transpors oxygen carbon dioxide hormones nutrients and waste. located within blood vessels white blood cells frequently leave the blood vessels. more red
Connective tissue has how many cells scattered along what kind of matrix? 
fewer cells scattered along NON living matric that is solid or semi solid. CT is the mot abundant by weight. 
diffusion occurs easily or harder with simple squamous et?
diffusion occurs easily
does Epithelial tissue have intercellular spaces?
NO and a small amount of substance. HAS BASEMENT MEMBRANE- which provides support for the epithelium and also binds it to neightboring structurs.
similar to hyaline, fibers more numerous. function flexible and located at disks
Functions of CT
enclosing and seperatin, connecting tissue to one another, supporting and moving, storing, cushioning, transporting and protecting cells. 
hyaline cartilage
function: allows growth of long bones, located in respiratory system
integumentary list some general info on it
Organ System, Dermatolog (study of skin)It is the largest organ by weight, includes 4 primary tissue types, and aids in excretion  of waste products
list the four types of membrans and what tissue i can find them in

ET and CT have Cutaneous (skin) Mucous (open) and Serous (close) Connective tissue has Synovial added on to its list

list the integumentary structure:
cutaneous membrane (dry) it has 2 layers Epiderms and the Dermis (with deeper hypodermis) and accessory structures like hair folicule, shaft and sweat glands. 
Loose Connective tissue
a fine network of fibers. mostly collagen fibroblasts located in here. Function is loose packing, support and nourish. Located thoughout the body underlying tissue skin dermis
name the 2 groups epithelial is divided into, and what are the names
simple: one layer and stratified: multiple layers. Simple can be subdived according to the shape and functoin of its cells.
name the connective tissue membrane
Synovial it lines freely moveable joint cavities (bursae, tendon sheaths) it lubricates and provides nutrients
name the structure, function and location of simple columnar epithelium tissue
single tall layer, function:movement of particles out of the lungs by cilitated cells. Goblet cells secrete musus. it protects absorbs and secretes and lines digestive track and uterus 
name the structure, function and location of simple cuboidal et
structure: single layer, some have microvilli or cillia. Function: active transport & facilitated diffusion in secretion & absobtion by cells. Located in kidney tubules, glands and their ducts.
name the structure, function and location of simple squamous epithelium

single layer-falt, diffusion, filtration, some secretion and protection, and located lining of blood vessels, heart, lungs, serous membrane body cavities. 


pseudostratified columnar et (struction:LAYERS, function and where we find it in the body
single layer of cells. function: synthesizes & secretes mucus onto free surface & moves. Location: lining the nasal cavity sinuses, trachea and lungs 
stratified cuboidal epithelium
more than one layer, found in sweat glands and functions in absorption and secretion
stratified Squamous ET structure function location
several layers that are cuboidal in the basal laye and flatter toward the surface . It protects against abrasion, barrier against infection and reduces loss of water from the body. dound in mouth throat skin esophagus.
the basement membrane can function as a what in epithelial cells?
can function as a filter & barrier for movement
transitional et is a special type of stratifies ET that can be greatly (what amanda loves to do)

STRETCHED itlines the urinary bladder

function is accomidating fluxuation in fluid volume  

transitional has how many layes and what shape? where is it located?
many layers and the cell shape changes-streche. location: lines the urinary bladder.
what are fibroblasts?  and what are Osteocytes?
are cells that form fibers abd ground substances in the matrix of C Tissue. Osteocytes maintain bone
what are the two folding layers of serous fulid?
1) parietal-lines wall of ventral body cavity lungs          2) Visceral- covers organs 
what tissue is on the top layer of skin
epithelial stratified squamous, superficial is dermis
where are squamous cells located?
they line body cavities like the mouth, blood vessels, heart and lungs and make up hte outer layer of the skin.
