Free Surface
Part of epithelial cells which is not in contact with other cells.
Basement Membrane
Attaches epithelial cells to underlying tissues.
Simple Cuboidal
Epitheliums with single layer of cube-shaped cells
Stratified Columnar
Epithelium with MULTIPLE layers of tall, thin cells
Transitional
Epithelim with layers of cells that appear cubelike when an organ is relaxed and flattened when the organ is distended by fluid
Simple squamous
Epithelium with SINGLE layer of FLAT, often HEXAGONAL cells
Pseudostratified
Epithelium with SINGLE layer of cells; some cells are TALL and THIN and reach the free surface, others do not
Stratified Squamous
Epithelium with multiple layers of cells in whih the deepest layers are cuboidal or columnar and becomes flattened at the surface.
Stratified Epithelium
Found in areas where PROTECTION is a major Function... SKIN, ANAL CANAL, and VAGINAL
Simple epithelium
Found in ORGANS where the princelpal functions are diffusion, filtration, secretion or absorption.
Squamous
Epithelial cells involved in diffusion or filtration
Cuboidal or Columnar
Epithelial cells with the major function of secretion or absorption
Smooth
Cell surface that REDUCES friction
Cilia
Proel materials along the cell surface
Microvilli
Greatly increase surface area; cylindrical extensions of the cell membrane.
Tight Junctions
Bind adjacent cells together and prevent the passage of materials between epithelial cels.
Desmosomes
Mechanical links that function to bind cells together; found in areas subjected to stress such as skin epithelium
Gap Junctions
Small channels that allow small molecules and ions to pass from one epithelial cell to another.
Exocrine
Gland with a duct (Sweat glands)
Endocrine
Glands with NO duct; screte hormones (Pituitary gland )
Collagen Finbers
Protein fibers that resemble microscopic ropes; flexible, but resist stretching.
Recticular Fibers
Fine short collagen fibers that branch
Elastic Fibers
Protein fibers with structure similar to a coiled bed spring.
Proteglycans
Ground substance molecules that trap water; composed of Protein and Polysaccharides.
Blast Cells
Cells that PRODUCE the extracellular matrix
Cyte cells
Cells that MAINTAIN the extracellular matrix
Clast Cells
Cells that BREAK DOWN the extracellular matric.
Macrophages
Cells that MOVE about and ingest foreign substances
Macropahge Move
Mast Cells
Nonmotile cells; RELEASE chemicals promoting inflammation.
Protein Fibers
Extracellular matric for dense and areolar connective tissue
Protein Fibers + Ground Substances
Extracellular matrix for cartilage and bone
Liquid
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
Widely separated collagen fibers running in random directions; attachment for organs, glands, muscles, nerves, and skin
Adipose Tissue
Very little matrix; cells filled with lipid for energy storage.
Hyaline Cartilage
Covers the ends of bones where bones come together to form juoints
Fibrocartilage
Found in the Disks between vertebrae
Elastic Cartilage
Found in the external ear
Bone
Hard Connective tissue consisting of living cells and a mineralized matrix.
Chondrocytes
Cartilage cells
Osteocytes
Bone Cells
Lacunae
Spaces containing cells within the matrix of bone or cartilage
Skeletal Muscle
Cylindrical, striated, voluntary muscle cells, with several nuclei per cell
Cardiac muscle
Striated, branching, involuntary cells with intercalated disks
Smooth muscle
Cells tapered at each end, unstriated, involuntary, and with a single nucleus
Cell body
Part of the neuron (nerve cell) that contains the nucleus; site of general cell functions.
Dendrite
Receive action potentials and conduct them toward the cell body
Axon
Conducts action potentials away from the cell body
Neuroglia
Support cells of the nervous system; function to nourish, portect and insulate the neurons
Mucous Mebranes
Line cavities that open to the outside of the body
Serous membrane
Line the trunk cavities and cover the organs located within the trunk cavities.
Other membranes
Includes skin, synovial membrane, and periosteum
Pleural
Serous membranes - LUNGS
Pericardial
Serous membranes - HEART
Peritoneal
Serous membranes - Abdominopelvic Cavity
