few cells, poor blood supply, thus slow healing cartilage all cartilage cells are called chondrocytes hyaline cartilage covers ends of joints, padding elastic cartilage external ear, larynx fibrocartilage tough, shock absorbing, located between vertebrae bone tissue osseus tissue, rigid due to mineral salts blood tissue circulates throughout the body muscle tissue skeletal, cardiac, smooth skeletal tissue striated and voluntary smooth tissue hollow organs, involuntary cardiac tissue wall of the heart nerve tissue found in the brain, spinal cord, and nerves neurons transmit impulses neuroglia protection and support

major types of tissue

epithelial, connective, muscular, nervous

functions of epithelial tissue

protection, secretion, , absorption, filtration, excretion, senses

simple

one layer

squamous

flat cells

stratified

multiple layers

cuboidal

cube shaped

columnar

column shaped

simple squamous shape

single layer of flat cells

simple squamous function

diffusion and filtration

simple squamous location

found in air sac of the lungs

simple cuboidal shape

single layer of cube shaped cells

simple cuboidal function

secretion and absorption

simple cubiodal location

kidney tubules, surface of ovaries

simple columnar shape

single layer of long cells, have goblet cells and microvilli

simple columnar function

secretion and absorption

simple columnar location

digestive tract and uterus

goblet cells

secrete mucus

microvilli

projections that increase the cell's surface area

stratified squamous shape

several layers, flat

stratified squamous function

protection

stratified squamous location

lines body cavities; skin and mouth

what happens when the dermis pulls away from epidermis

blisters form

collagen and elastin

connective tissue

pseudostratified columnar shape

single layer with nuclei at various levels, can have goblet cells and cilia

pseudostratified columnar function

secretion and cilia-aided movement

pseudostratified columnar location

linings of respiratory passages, tubes of reproductive system

transitional epithelium shape

thick, layered cuboidal cells

transitional epithelium function

stretchable tissue, forms barrier to block diffusion

transitional epithelium location

urinary bladder

glandular epithelium

cells that are specialized to produce and secrete substances, makes up the body's glands

connective tissue

most abundant tissue in your body, binds structures together

connective tissue function

provides support, prtoection, framework, fills space, stores fat, produces blood cells, fights infection

connective tissue composed of

scattered cells within a matrix, a ground substance and fibers

common types of connective tissue cells

mast cells, macrophages, fibroblasts

main types of fibers

collagenous and elastic

collagenous fibers

strong, flexible, not very elastic, found in bones, ligaments

elastic fibers

not as strong, very elastic, found in ears, vocal

areolar tissue (loose connective tissue)

binds skin to underlying organs, forms thin membranes throughout body

adipose tissue (fat)

protective cushion, insulation to preserve body heat, stores energy

fibrous connective tissue

thick collagenous fibers and fine network of elastic fibers- few cells, poor blood supply, thus slow healing

cartilage

all cartilage cells are called chondrocytes

hyaline cartilage

covers ends of joints, padding

elastic cartilage

external ear, larynx

fibrocartilage

tough, shock absorbing, located between vertebrae

bone tissue

osseus tissue, rigid due to mineral salts

blood tissue

circulates throughout the body

muscle tissue

skeletal, cardiac, smooth

skeletal tissue

striated and voluntary

smooth tissue

hollow organs, involuntary

cardiac tissue

wall of the heart

nerve tissue

found in the brain, spinal cord, and nerves

neurons

transmit impulses

neuroglia

protection and support
