Matrix is composed of an amorphous ground substance consisting of molecules that expand when water molecules and electrolytes bind to them. As much as 90% of connective tissue is ground substance. Fibers make up the other component of matrix.MEIOSIS,A type of cell division in which each daughter cell receives half the normal number of chromosomes, forming two reproductive cells.MEMBRANE,A thin, sheetlike layer of tissue that covers a cell, an organ, or some other structure; that lines a tube or a cavity, or that divides or separates one part from another.METABOLISM,Chemical processes in the body that convert food and air into energy to support growth, distribution of nutrients, and elimination of waste.METABOLITES,Molecules synthesized or broken down inside the body by chemical reactions.MICROVILLI,Small projections of the cell membrane that increase the surface are of a cell.MITOCHONDRIA,Cell organelles of rod or oval shape that provide energy for cellular activity.MITOSIS,Cell division in which the cell duplicates its DNA and divides into two identical daughter cells.MOLECULE,A combination of two or more atoms. A molecule is the smallest portion of a substance that can exist separately without losing the physical and chemical properties of that substance.MUSCLE TISSUE,A specialized form of tissue that contracts and shortens to provide movement, maintain posture, and produce heat.NERVOUS TISSUE,A specialized tissue that coordinates and regulates body activity. It can develop more excitability and conductivity than other types of tissue.NUTRIENTS,Essential elements and molecules that are obtained from the diet and that are required by the body for normal body fuction.ORGANELLES,The basic components of a cell that perform specific functions within the cell.ORGANIC COMPOUNDS,Substances that have carbon and hydrogen as part of their basic structure.OSMOSIS,Diffusion of water from a region of lower concentration of solution to a region of higher concentration of solution across the semipermeable membrane of a cell.PASSIVE TRANSPORT,Transportation of a substance across the cell membrane without the use of energy.PHAGOCYTOSIS,The process of endocytosis followed by digestion of the vesicle's contents by enzymes present in the cytoplasm.PHOSPHOLIPID BILAYER,Cell membrane made up of lipids, carbohydrates, and proteins.PHYSIOLOGY,The study of the structures of a particular area of the body.
