| Term | Definition |
|---|---|
| Human Anatomy | the scientific study of the body’s structures. |
| Gross Anatomy | the study of the larger structures of the body, those visible without the aid of magnification. |
| Macro | means "large" |
| Micro | means "small" |
| Cytology | the study of cells |
| Histology | the study of tissues |
| Regional Anatomy | the study of the interrelationships of all of the structures in a specific body region. |
| Systemic Anatomy | is the study of the structures that make up a discrete body system; that is, a group of structures that work together to perform a unique body function. |
| Human Physiology | the scientific study of the chemistry and physics of the structures of the body and the ways in which they work together to support the functions of life. |
| homeostasis | the state of steady internal conditions maintained by living things. |
| neurophysiology | the study of the brain, spinal cord, and nerves and how these work together to perform functions as complex and diverse as vision, movement, and thinking. |
| Cell | the smallest independently functioning unit of a living organism. |
| Elements | the unique pure substances that make up matter. |
| Atom | the smallest component of an element, characterized by a sharing of the chemical properties of the element and a nucleus with neutrons, protons and electrons |
| Molecule | a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction. |
| cytoplasm | the material or protoplasm within a living cell, excluding the nucleus. |
| organelles | subcellular structure that has one or more specific jobs to perform in the cell. |
| tissue | a group of many similar cells (though sometimes composed of a few related types) that work together to perform a specific function. |
| organ | an anatomically distinct structure of the body composed of two or more tissue types. |
| organ system | a group of organs that work together to perform major functions or meet physiological needs of the body. |
| Organism | a living being that has a cellular structure and that can independently perform all physiologic functions necessary for life. |
| blood vessels | tubular structure carrying blood through the tissues and organs; a vein, artery, or capillary. |
| integumentary system | largest organ system; includes the skin, hair, and nails. |
| skeletal system | supports the body and enables movement; includes cartilage, bones, and joints. |
| muscular system | enables movements and helps maintain body temperature; includes skeletal muscles and tendons |
| nervous system | detects and processes sensory information and activates bodily responses; includes the brain, spinal cord, and peripheral nerves. |
| endocrine system | secretes hormones and regulates bodily processes; includes the pituitary gland, thyroid gland, pancreas, adrenal glands, and testes or ovaries |
| cardiovascular system | delivers oxygen and nutrients to tissues and equalizes temperature in the body; includes the heart and blood vessels. |
| lymphatic system | returns fluid to the blood and defends against pathogens; includes the thymus, lymph nodes, spleen, and lymphatic vessels. |
| respiratory system | removes carbon dioxide from the body and delivers oxygen to the blood; includes the trachea, lungs, and nasal passage. |
| digestive system | processes food for use by the body and removes wastes from undigested food; includes the stomach, liver, gall bladder, large intestine, and small intestine. |
| urinary system | controls water balance in the body and removes wastes from the blood and excretes them; includes kidneys and urinary bladder. |
| male reproductive system | produces sex hormones and gametes and delivers gametes to female; includes epididymis and testes. |
| female reproductive system | produces sex hormones, supports embryo/fetus until birth, and produces milk for infant; includes mammary glands, ovaries, and uterus |
