What are the four stages of mitosis? 1.Prophase 2.Metaphase 3.Anaphase 4.Telophase
Endoplasmic Reticulum Organelle composed of a system of connected membranous tubules and vessicles, along which protein is synthesized.
Dialysis Separation of smaller (diffusable) particles from larger (non-diffusable) particles through a semipermeable membrane.
Deoxyribonucleic Acid DNA - genetic material a double stranded polymer-stranded polymer of nucleotides.
Inflammation Dilation of blood vessels in affected tissues.Skin is reddened, swollen, and painful to touch.
Adenosine Triphosphate (ATP) Organic molecule that stores and releases energy which may be used in cellular processes.

Simple Columnar Tissue Single layer of tall narrow cells.
Collagen Protein in connective tissue and in bone matrix.
Keratinization Process by which cells form fibrils of Keratin and harden.
Eccrine Glands Respond to an elevated body temperature, environmental heat or physical exercise.Common on the forehead, neck, and back.
Epitheal Tissue Covers body surfaces & organs. Forms inner lining of body cavities & lines hollow organs.Lacks blood vessels. Cells are tightly packed.
Exocytosis Exo(external) cytosis (cell)
Exocytosis is defined as? A process in which a cell directs the contents of secretory vessicles out of the cell membrane. Ex: hormones
Phagocytosis Process by which a cell engulfs and digests solids. (literally cell eating)

Transcription Manufacturing a complimentary RNA from DNA
Organelle Part of a cell that performs a specialized function.
Endocytosis The process by which cells absorb molecules from outside the cell by engulfing it with their cell membrane.
Nucleoplasm A special type of cytoplasm found in the nucleus.
Osteon Cylinder shaped unit including bone cells that surround a central canal.
Collagenous Cells Thick threads of protien collagen grouped in long parallel bundles. Flexible but only elastic. Provides great tensile strength.

Cytoplasm Contents of a cell exluding the nucleus and cell membrane.
Cuboidal cell shape resembling a cube.
Basement Membrane Layer of extracellular matrix that anchors epithelial tissue to underlying connective tissues.
Keratin Protien in epidermis hair and nails.
What are the 4 major tissue types? 1.Epithelial 2.Connective 3.Muscle 4.Nervous
Stratum Basale The deepest layer of the epidermis. Contains cells undergoing mitosis. These cells are nourished by dermal blood vessels.
Epidermis The epidermis is stratified squamous epithelial tissues. The outermost layer of the epidermis composed of dead cells. The bottom is composed of living cells.
Osmosis Diffusion of water through a selectively permeable membrane in response to a concentration gradient.
Areolar Connective tissue consisting of fibers and a cariety of cells embedded in a loose matrix of soft sticky gel.
Integumentary System The skin and accessory organs.
Which gland is responsible for sweat? Sudoriferous gland
