Tissues

TermDefinition
epithelial tissue closely spaced cells that cover the skin function: protection, absorption, filtration, secretion
simple squamous one layered thin cell function: diffusion and filtration location: blood vessels
simple cuboidal one layered cube shaped cells function: secretion and absorption location: kidney tubules
simple columnar one layered tall shaped cell function: secretion or mucus and enzymes location: digestive tract
keratinized stratified squamous keratin filled dead surface cells function: protection from abrasion location: epidermis
non keratinized stratified squamous no keratin alive surface cells function: protection in moist areas location: mouth, esophagus
pseudo stratified columnar appears layered but all cells touch base, ciliated function: secretes mucus and moves it location: trachea, upper respiratory tract
transitional cells change shape when stretched function: allows stretching location: urinary bladder
connective tissue cells packed loosely surrounded by extracellular matrix
loose connective tissue more ground substance less fibers
areolar lc tissue function: wraps cushions and holds tissues together location: around organs
reticular lc tissue function: forms supportive framework location: lymph nodes, bone marrow
adipose lc tissue function: insulation, energy/fat storage location: under skin
dense connective tissue more fibers less ground substance
dense regular same direction fibers function: strong attachment location: tendons and ligaments
dense irregular fibers in many directions function: strength in multiple directions location: dermis of skin
elastic dc tissue function: stretch and recoil location: lungs, large arteries
supportive connective tissues cartilage
hyaline cartilage function: support and cushioning location: nose, trachea, ends of bones
fibrocartilage function: shock absorption location: invertebral discs
elastic cartilage function: maintains shape with flexibility location: ear
compact bone looks like: tree rings function: support and protection location: outer portion of bone
spongy bone looks like: spread out spaces function: houses marrow location: ends of long bones, inside
erythrocytes looks like: small round no nucleus function: transport oxygen and co2 location: blood
leukocytes looks like: small with nucleus function: fight infection location: blood and tissues
platelets looks like: small cell fragments functions: blood clotting location: blood
muscle tissue produces movement
skeletal muscle looks like: long striated multinucleated function: voluntary movement location: attached to bones
cardiac muscle looks like: striated branching cells, one nucleus function: pumps blood location: heart
smooth muscle looks like: non- striated single nucleus function: move substances through organs location: digestive tract, vessels, uterus
nervous tissue communication made of neurons and glial cells
neuron looks like: circle with branches coming out function: transmit electrical signals location: brain, spinal chord, nerves
dendrites looks like: branches coming off cell body function: receive signals location: neuron
cell body looks like: main central part of neuron function: integrates incoming signals location: neuron
axon hillock looks like: beginning of axon function: initiates action location: between cell body and axon
axon looks like: long branch off cell body function: sends impulses away location: neuron
glial cells looks like: other circles and branches around the neuron function: protect and insulate neurons location: around neurons

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
