| Term | Definition |
|---|---|
| anatomy | is the branch of biology and medicine that studies the structure of living organisms |
| cell | is the basic structural, functional, and biological unit of all living organisms |
| cell membrane | is the thin, flexible barrier that surrounds a cell, separating its internal contents from the external environment. |
| centro some | is a cell organelle that serves as the main microtubule-organizing center (MTOC) in animal cells. |
| chromatin | is a complex of DNA and proteins (mainly histones) found in the nucleus of eukaryotic cells. |
| congenital | refers to a condition or trait that is present at birth, whether inherited genetically or caused by factors affecting development before birth. |
| connective tissue | is a type of tissue in the body that supports, connects, and protects other tissues and organs. It is one of the four basic tissue types, along with epithelial, muscle, and nervous tissue. |
| cytoplasm | is the jelly-like substance inside a cell, located between the cell membrane and the nucleus, that surrounds and supports the cell’s organelles. |
| degenerative | refers to a condition or process in which tissues, organs, or body functions gradually deteriorate or lose their normal function over time. |
| dehydration | is a condition that occurs when the body loses more water than it takes in, leading to insufficient fluids to carry out normal bodily functions. |
| diagnosis | is the process of identifying a disease, condition, or injury based on a patient’s signs, symptoms, medical history, and test results. |
| edema | is the swelling caused by the accumulation of excess fluid in the tissues of the body, usually under the skin or in body cavities. |
| endoplasmic reticulum | is a network of membranous tubes and sacs within the cytoplasm of eukaryotic cells that plays a major role in synthesizing, folding, and transporting proteins and lipids. |
| epithelial tissue | is a type of tissue that covers the body surfaces, lines internal organs and cavities, and forms glands. It acts as a protective barrier and is involved in absorption, secretion, and sensation. |
| etiology | is the study of the cause or origin of a disease or medical condition. It explains why a disease occurs rather than just describing its symptoms. |
| genes | are units of heredity made of DNA that carry instructions for building and maintaining an organism’s traits and functions. They determine how your body develops and works. |
| genome | is the complete set of genetic material (DNA) in an organism, including all of its genes and non-coding sequences. It contains all the instructions needed to build and maintain that organism. |
| golgi apparatus | is a cell organelle that modifies, sorts, and packages proteins and lipids for storage or transport out of the cell. |
| homeostasis | is the body’s ability to maintain a stable internal environment despite changes in the external environment. |
| infectious | refers to a disease or condition that is caused by microorganisms (such as bacteria, viruses, fungi, or parasites) and can be spread from one person, animal, or object to another. |
| inherited | refers to traits, characteristics, or conditions that are passed from parents to their offspring through genes. |
| lysosomes | are small, membrane-bound organelles in eukaryotic cells that contain digestive enzymes. |
| meiosis | are small, membrane-bound organelles in eukaryotic cells that contain digestive enzymes. |
| mitochondria | are membrane-bound organelles in eukaryotic cells that produce energy for the cell. |
| mitosis | is a type of cell division in eukaryotic cells that produces two genetically identical daughter cells, each with the same number of chromosomes as the original cell. |
| muscle tissue | is a type of cell division in eukaryotic cells that produces two genetically identical daughter cells, each with the same number of chromosomes as the original cell. |
| nerve tissue | is a specialized type of tissue in the body that is responsible for transmitting electrical signals (nerve impulses) between different parts of the body and the brain or spinal cord. |
| nucleolus | is a small, dense, spherical structure found inside the nucleus of a cell. |
| nucleus | is a membrane-bound organelle found in eukaryotic cells that serves as the control center of the cell. |
| organ | is a structure in the body made up of two or more different types of tissues that work together to perform a specific function or set of functions. |
| organelles | are specialized structures within a cell that perform specific functions necessary for the cell’s survival and proper functioning. |
| pathophysiology | is the study of how normal physiological processes are altered by disease or injury. |
| physiology | is the scientific study of how living organisms and their parts function. |
| pinocytic vesicles | are small, fluid-filled sacs formed by the cell membrane to bring extracellular fluid and dissolved substances into the cell. |
| prognosis | is the medical prediction of the likely course, outcome, or recovery from a disease or medical condition. |
| protoplasm | is the living substance inside a cell, encompassing everything within the cell membrane except the cell wall |
| stem cells | is a special type of cell that has the ability to both self-renew (make copies of itself) and differentiate |
| system | is a group of organs that work together to perform a specific function or set of functions in the body. |
| tissue | is a group of similar cells that work together to perform a specific function in the body. |
| vacuoles | are membrane-bound sacs within a cell that store substances such as water, nutrients, waste products, or other materials. |
