nervous

simple squamous

diffusion, osmosis, filtration where no protection needed - kidney, alveoli lungs, heart/blood vessel lining

simple cuboidal

absorption/secretion - kidney tubules, ducts and secretory portions of small glands

simple columnar

absorption and secretion (mucus) - lines digestive tract (stomach/intestines - takes in nutrients) small bronchi, uterine tubes/uterus

pseudostratified columnar

secretion; can propel mucus - sperm carrying ducts, line trachea and upper respiratory tract; not stiff for movement

stratified squamous

protects underlying tissues in abrasive areas - lining of esophagus, mouth, vagina, epidermis

transitional (cuboidal/squamous)

stretches to allow digestion of urinary organ (expands and reverts) - lines ureters, bladder, and urethra

areolar

wraps/cushions other organs, inflammation, holds tissue fluid - under epithelia, packaging organs and surrounding capillaries

adipose

provides fuel for energy, insulates heat loss, cushions and protects - under skin around kidneys, in abdomen and breasts

dense regular (more fibers, dense, uniform)

attaches muscle to bone and bone to bone, withstands stress - tendons, ligaments

dense irregular (more going on)

withstands stress and tension from many directions - surrounds organs and joints, dermis of skin, digestive tract

elastic connective

allows recoil of tissue following stretching (heart beats, lungs) - walls of large arteries, within walls of bronchiole tubes

hyaline cartilage (not one shape)

supports and reinforces, serves as resilient cushion, resists compressive stress - embryonic skeleton, long end of bones, nose/trachea/larynx

elastic cartilage (more stretchy than hyaline) SOUND

maintains shape of structure while flexibility - supports external ear; epiglottis

fibrocartilage (not as flexible)

ability to absorb compressive shock - intervertebral disks, pubic symphysis, menisci of knee

bone

supports/protects, cell formation, Ca+ mineral storage - bones

blood

transport of respiratory gases, nutrients, wastes - contained within blood vessels

skeletal muscle (stripes)

voluntary movement, locomotion - skeletal muscles, attached to bones

cardiac muscle

involuntary movement, contraction propels circulation - walls of heart

smooth muscle (like squamous)

involuntary, propels substances (food) along internal passageways - walls of hollow organs (digestive)

nervous

electrical signals for communication/control - brain, spinal cord, nerves
