Question | Answer |
---|---|
What is Gross Anatomy? | science of macroscopic anatomy; studying large body structures without the use of a microscope |
What is Anatomy? | the study of the form or structure of body parts and how these parts relate to one another |
What is Physiology? | the study of the functions of the body parts |
What is Surface Anatomy? | the study of morphology and markings of the human body |
What is Regional Anatomy? | the study of the specific regions of the body such as the head and extremities |
What is Systematic Anatomy? | the study of specific systems in the body such as skeletal and and digestive |
What is Microscopic Anatomy? | the study of body tissues using a microscope |
Cytology | study of the cells in the body |
Histology | study of the tissues in the body |
Radio-graphic Anatomy | study of the structure of the body that involves using x-rays |
Embryology | study of the development of the fertilized egg through the 8th week utero |
Pathological Anatomy | study of diseased body structured |
Cell Physiology | study of cell function |
Pathophysiology | study of disease functions and processes |
Immunology | study of the functions of the immune system |
Neurophysiology | study of the functions of the nervous system |
Cardiovascular | study of the functions of the heart and blood vessels |
atoms | building blocks of matter |
elements | units composed of identical atoms |
molecules | various types and numbers of elements bonded together (water and protein) |
organelles | functional units of cells composed in various molecules |
cells | structural and functional units of an organism |
tissues | group of cells with similar structure and function |
organ | structure composed of two or more tissue types |
organ systems | collection of organs that work towards a common purpose |
organism | functional collection of many organ systems |
Moment: Muscular system contraction | propelling the whole organism or substances through the body via smooth muscles |
Responsiveness/irritability | ability of the organism to adapt to changes in the environment |
Digestion | break down of food, both chemically and physically, into simple nutrients that the body can use |
Metabolism | all of the chemical reactions/activities of an organism |
Anabolic Reactions | are synthesis reactions that typically use energy |
Catabolic Reactions | reactions associated with breaking down substances for the release of energy |
Excretion | removing harmful waste products from the organism (elimination, excretion, and the breathing process are examples) |
Reproduction | at the organismal level it is the production of offspring to ensure survival of the species |
Growth | increase in cell number and size attributing to increase in overall size of the organism |
Homeostasis | ability of the body to maintain equilibrium internally despite a continually changing world externally |
