Term
composed of flat sheets of tight cells. A surface tissue. Not just outer surfaces, inner surfaces too.
A. Protect: from outside invaders, from UV rays, from excessive water loss.
B. Transport: such as air in lungs.
C. Secretion: such as mucus or enzymes.
D. Produces: reproductive cells such as eggs and sperm.
Definition
Epithelial/Epithelium
Term
always suspended in intercellular matrix.
Definition
Connective cells
Term
plasma is the liquid or intercellular matrix that cells are suspended in.
Definition
Blood
Term
red cells, transports oxygen
Definition
erythrocytes
Term
white cells, invisible/no color for protection
Definition
leukocytes
Term
Platelets for blood clotting
Definition
thrombocytes
Term
composed of cells suspended in an open weave of protein fibers. Binds and attaches things together (ex: skin to underlying muscles).
Definition
Loose
Term
cells suspended in a dense matrix of protein fibers (ex: tendons connect muscle to bone and ligaments connect bones to bones).
Definition
Fibrous
Term
good to provide support and protein gives them some flexibility. Fewer cells than other tissues. Provides protection (ex: ribs). Makes blood cells.
Definition
Bone
Term
mix of tough protein and stretchy protein. Lots of fluid in intercellular matrix found in ears, nose, between bones/vertebrae. No blood supply so doesn’t heal well.
Definition
cartilage
Term
aka fat. Composed of cells that are fairly close together. Oil filled cells (or triglyceride). Isolation, protection, energy.
Definition
adipose
Term
composed of cells that have the ability to contract
Definition
Muscle
Term
attached to bones by way of tendons. Voluntary movement.
Definition
skeletal muscle
Term
involuntary movement. Such as, internal organs, etc.
Definition
visceral muscle
Term
heart muscle only. Involuntary (except you can learn to slow heartbeat). Great endurance.
Definition
Cardiac
Term
composed of cells called neurons and have the ability to conduct or transmit an impulse.
Definition
nervous system
