Terms
What is Anatomy?
The study of the form and structure of an organism.
what is a Cell membrane?
The outer protective covering of the cell. It is also called the plasma membrane. It is semipermeable.
what is Dehydration?
A condition that occurs if there is an insufficient amount (not enough tissue fluid).
what are Genes?
The structures that carry inherited characteristics.
what is a Cytoplasm?
A semifluid inside the cell but outside the nucleus. It contains water, proteins, lipids, carbohydrates, minerals, and salts. It is the site for all chemical reactions.
Organ
Two or more tissues joined together to perform a specific function.
Mitosis
The process by which most cells reproduce by dividing into two identical cells. It is a form of asexual reproduction.
Muscle tissue
Produces power and movement by contraction of muscle fibers. (Three main kinds: skeletal, cardiac, and visceral.)
what is Chromatin?
Located in the nucleus and made of deoxyribonucleic acid (DNA) and protein. During cell reproduction, it condenses to form rod-like structures called chromosomes.
System
Organs and other body parts joined together to perform a particular function.
what is a Nucleus?
A mass in the cytoplasm, often called the "brain" of the cell because it controls many cell activities and is important in mitosis.
what is the Centrosome?
Located in the cytoplasm and near the nucleus. It contains two centrioles. During mitosis, the centrioles separate.
what is Endoplasmic reticulum?
A fine network of tubular structures located in the cytoplasm. This network allows for the transport of materials and aids in the synthesis and storage of proteins.
Physiology
The study of the processes of living organisms, or why and how they work.
Pathophysiology
The study of how disease occurs and the responses of living organisms to disease processes.
Diagnosis
dentifying the disease or stating what it is.
Degenerative
Caused by a deterioration of the function or structure of body tissues and organs either by normal body aging or lifestyle choices.
Golgi apparatus
A stack of membrane layers located in the cytoplasm. This structure produces, stores, and packages secretions for discharge from the cell.
what is Inherited?
Transmitted from parents to child genetically.
Vacuoles
Pouchlike structures found throughout the cytoplasm that are filled with a watery substance, stored food, or waste products.
what is Epithelial tissue?
Covers the surface of the body and is the main tissue in the skin. It forms the lining of tracts and body cavities, and forms body glands.
What are Pinocytic vesicles?
Pocketlike folds in the cell membrane. These folds allow large molecules such as proteins and fats to enter the cell.
what are Lysosomes?
Oval or round bodies found throughout the cytoplasm. These structures contain digestive enzymes that digest and destroy old cells, bacteria, and foreign materials.
what are Homeostasis?
A constant state of natural balance within the body.
what is a Mitochondria?
Rod-shaped organelles located throughout the cytoplasm, often called the "furnaces" or "powerhouses" of the cell because they produce adenosine triphosphate (ATP), the major energy source.
