Attaches epithelial cells to underlying tissue
Epithelium with single layer of cube-shaped cells
Epithelium with multiple layers of tall, thin cells
Epithelium with layers of cells that appear cubelike when an organ is relaxed and flattened when the organ is distended by fluid.
Epithelium with single layer of flat, often hexagonal cells.
Epithelium with single layer of cells; some cells are tall and thin and reach the free surface, and others do not.
Epithelium with multiple layers of cells in which the deepest layers are cuboidal or columnar and become flattened at the surface.
Found in areas where protection is a major function, e.g., skin, anal canal, and vagina.
Found in organs where the principal functions are diffusion, filtration, secretion or absorption.
Epithelial cells involved in diffusion or filtration.
Epithelial cells with the major finction of secretion or absorption.
Glands with a duct (e.g., sweat glands).
Glands with no duct; secrete hormones (e.g. pituitary gland).
Bind adjacent cells together and prevent the passage of materials between epithelial cells.
Mechanical links that function to bind cells together; found in areas subjected to stress such as skin epithelium.
Small channels that allow small molecules and ions to pass from one epithelial cell to another.
Extracellular matrix for dense and areolar connective tissue.
protein fibers + ground substance
Extracellular matrix for cartilage and bone.
Extracellular matrix for blood.
dense connective tissue
Closely packed collagen fibers running in the same direction; found in tendons, ligaments, and the dermis of the skin.
loose (areolar) connective tissue
Widely separated collagen fibers running in random directions attachment for organs, glands, muscles, nerves, and skin.
Very little matrix; cells filled with lipid for energy storage.
Covers the ends of bones where bones come together to form joints.
Found in the disks between vertebrae.
Found in the external ear.
Hard connective tissues consisting of living cells and a mineralized matrix.
Cylindrical, striated, voluntary muscle cells with several nuclei per cell.
Striated, branching, involuntary cells with intercalated disks.
Cells tapered at each end, unstriated, involuntary, and with a single nucleus.
Part of the nueron (nerve cell) that contains the nucleus; site of general cell function.
Recieve action potentials and conduct them toward the cell body.
Conducts action potentials away from the cell body.
Support cells of the nervous system; function to nourish, protect and insulate the neurons.
mediators of inflammation
Chemical substances that are released or activated in the injured tissues and adjacent blood vessels.
dilation and increased permeability
2 changes that occur in blood vessels that result in symptoms of redness, heat, and swelling.
Swelling of tissues when proteins and water from blood enter tissues.
Phagocytic white blood cells that fight infection; dead cells in pus.
Result of direct damage, mediators, and edema stimulating nerve cell endings.
disturbance of function
Limitations produced by edema, tissue destruction, and pain.
Line cavities that open to the outside of the body.
Line the truck cavities and cover the organs located within the truck cavities.
Includes, skin, synovial membrane, and periosteum.
The new cells are of the same type as those that were destroyed.
A new type of tissue develops that eventually causes scar production and the loss of some tissue function.
Continue to divide throughout life; these cells can be completely repaired by regeneration.
Do not actively divide after growth ceases, but they do retain the ability to divide after an injury, and are capable of regeneration.
Cannoth divide, and if killed, they are usually replaced by connective tissue.
Cell surface that reduces friction.
Propel materials along the cell surface.
Greatly increase surface area; cylindrical extensions of the cell membrane.
Protein fibers that resemble microscopic ropes; flexible, but resist stretching.
Fine short collagen fibers that branch.
Protein fibers with structure similar to a coiled bed spring.
Ground substance molecules that trap water; composed of proteins and polysaccharides.
Cells that produce the extracellular matrix.
Cells that maintain the extracellular matrix.
Cells that break down the extracellular matrix.
Cells that move about and ingest foreign substances.
Nonmotile cells; release chemicals promoting inflammation.
Spaces containing cells within the matrix of bone or cartilage.
Serous membranes associated with the lungs.
Serous membranes associated with the heart.
Serous membranes associated with the abdominopelvic cavity.
A threadlike protein that binds the edges of the wound together and stops the bleeding.
The surface of the clot dries to form a ______.
removes dead neutrophils, cellular debris, and the decomposing clot.
a delicate connective tissue that replaces the clot consisting of fibroblasts, collagen, and capillaries.
when a large amount of granulation tissue persists.
when fibroblasts pull the edges of the wound closer together.
