Unit 7.1 key terms
| Term | Definition |
|---|---|
| anatomy | the study of the structure of an organism |
| cell | mass of protoplasm; the basic unit of structure of all animals and plants |
| cell membrane | outer protective, semipermeable covering of a cell |
| centrosome | that area of cell cytoplasm that contain two centrioles; important in reproduction of the cell |
| chromatin | a part of a cell located in the nucleus and made of deoxyribonucleic acid and protein; during cell reproduction, condenses to form chromosomes |
| congenital | acquired during development of the infant in the uterus and present at birth |
| connective tissue | body tissue that connects, supports, or binds body organs |
| cytoplasm | the fluid inside a cell; contains water, proteins, lipids, carbohydrates, minerals, and salts |
| degenerative | disease type, caused by a deterioration of the function or structure of body tissues and organs either by normal body aging or lifestyle choices such as diet and exercise |
| dehydration | insufficient amounts of fluid in the tissues |
| diagnosis | determination of the nature of a person's disease |
| edema | swelling; excess amount of fluid in the tissues |
| endoplasmic reticulum | fine network of tubular structures in the cytoplasm of a cell; allows for the transport of materials in and out of the nucleus and aids in the synthesis and storage of protein |
| epithelial tissue | tissue that forms the skin and parts of the secreting glands, and that lines the body cavities |
| etiology | the study of the cause of a disease |
| genes | the structures on chromosomes that carry inherited characteristics |
| genone | the total mass of genetic instruction humans inherit from their parents |
| golgi apparatus | the structure in the cytoplasm of a cell that produces, stores, and packages secretions from discharge from the cell |
| homeostasis | a constant state of natural balance within the body |
| infectious | invasion by organisms; contamination by diesease-producing organisms, or pathogens |
| inherited | a disease transmitted from parents to child genetically |
| lysosomes | the structures in the cytoplasm of a cell that contain digestive enzymes to digest and destroy old cells, bacteria, and foreign matter |
| meiosis | the process of cell division that occurs in gametes, or sex cells |
| mitochondria | the structures in a cell that provide energy and are included in the metabolism of the cell |
| mitosis | process of asexual reproduction by which cells divide into two indentical cells |
| muscle tissue | body tissue composed of fibers that produce movement |
| nerve tissue | body tissue that conducts or transmits impulses throughout the body |
| nulceolus | the spherical body in the nucleus of a cell that is important in reproduction of the cell |
| nulceus | the structure in a cell that controls cell activities such as growth, metabolism, and reproduction |
| organ | body part made of tissues that have joined together to perform a special function |
| organelles | structures in the cytoplasm of a cell, including the nucleus, mitochondria, ribosomes, lysosomes, and golgi apparatus |
| pathophysiology | study of how disease occurs and the responses of living organisms to disease processes |
| physiology | the study of the processes or functions of living organisms |
| pinocytic vesicles | pocket like folds in the cell membrane that allow large molecules such as proteins andfats to enter the cell |
| prognosis | prediction regarding the probable outcome of a disease |
| protoplasm | thick, viscous substance that is the physical basis of all living things |
| stem cells | cells that are capable of becoming any of the specialized cells in the body; two main types include embryonic stem cells from a developing set and somatic or adult stem cells |
| systems | a group of organs and other parts that work together to perform a certain function |
| tissue | a group of similar cells that join together to perform a particular function |
| vacuoles | pouch like structures found throughout the cytoplasm that have a vacuolar membrane with the same structure as the cell membrane |
| zygote | single celled embryo |
