Tissues

Front 1

simple squamous

Back 1

flat, allows materials to pass through diffusion and filtration, secretes lubricating substances in serosae. found kidneys and air sacs

Front 2

simple cuboidal

Back 2

cubelike, secretion and absorbtion, found kidney tubules ovary surface

Front 3

simple columnar

Back 3

single lyer column like cells, absorption, secretion of mucus enzyme and other substances, found in lining of digestive tract

Front 4

pseudostratified columnar

Back 4

single layer of cells column like but cells differentiate in height, secretes substances, found in the trachea

Front 5

stratified squamous

Back 5

thick membrane composed of several cell layers, protects underlying tissues in areas of abrasion

Front 6

stratified cuboidal

Back 6

two layers of cubelike cells, protection, found in sweat glands mammary glands and salivary glands

Front 7

stratified columnar

Back 7

several cell layers columnar, protection and secretion, found in urethra

Front 8

transitional

Back 8

resembles both stratified squamous and stratified cuboidal or columnar, stretches readily and permits distension of urinary organ by contained urine, found lining the ureters, urinary bladder, and parts of the urethra

Front 9

embryonic connective

Back 9

gel like ground substance containing fibers star shaped mesenchymal cells, gives rise to all other connective tissue types, found primarily in embryo

Front 10

connective tissue proper; loose connective tissue, aerolar

Back 10

gel like matrix with all 3 fibers types cells: fibroblast, macrophages, mast cells, and some white blood cells

Front 11

connective tissue proper: loose connective tissue, adipose

Back 11

gel like matrix, sparse, closely packed adipocytes, or fat cells have nucleus pushed to side by large fat droplets; provides reserve fuel, insulates against heat loss; supports and protects organs

Front 12

connective tissue proper: loose connective tissue, reticular

Back 12

network of reticular fibers in a typical loose ground substance; reticular cells lie on the network. fibers form a soft internal skeleton that supports other cell types, found in the lymphoid organs

Front 13

cartilage

Back 13

similar to hyaline cartilage but more elastic fibers in the matrix. maintains the shape of a structure while allowing great flexibility, found in ears and epiglottis

Front 14

cartilage, fibrocartilage

Back 14

matrix similar to but less firm than the hyaline cartilage; thick collagen fibers; tensile strength wit the ability to absorb compressive shock, found in the intervertebral discs and knee joints

Front 15

connective tissue proper, dense connective tissue

Back 15

primarily parallel collagen fibers, a few elastic fibers major cell type is fibroblast,; attaches muscle to bone or to muscle, found in tendons and ligaments

Front 16

connective tissue proper dense connective tissue elastic

Back 16

dense regular tissue containing high portions of elastic fibers; allows recoil of tissue following stretching, walls of large arteries, aorta

Front 17

connective tissue proper, dense connective tissue dense regular

Back 17

primarily irregularly arranged collagen fibers some elastic fibers major cell is fibroblast; able to withstand tension exerted in many directions provieds structural support; found in the dermis of skin and shoulder joints

Front 18

cartilage, hyaline

Back 18

amorphous but firm matrix collagen fibers form an immperceptible network chondroblasts produce the matrix and when mature lie in lacunae; supports and reinforces serves as resilient cushion resists compressive stress; found in costal cartilage

Front 19

bone osseus tissue

Back 19

hard calcified matrix containing many collagen fibers; support and protects; bones

Front 20

blood

Back 20

red and white blood cells in a fluid matrix; transport of respiratory gases nutrient wastes and other substances; contained within blood vessels
