The body can be subdivided into 2 major divisions. | Axial and appendicular |
Anatomy is the study of | structure of an organism and the relationships of its parts. |
Physiology is the study of | functions of the living organism and its parts. |
Characteristics of human life | Responsiveness conductivity growth respiration digestion absorption secretion excretion circulation reproduction |
Mitochondria | Powerhouses of cells that provide energy needed by the cell to carry on day to day functioning, growth & repair. Organelle. |
Golgi Apparatus | Set of sacs that provide packaging service to the cell by storing material for future internal or export of the cell. Organelle |
Endoplasmic reticulum | Network of channels within the cell that acts as a highway for movement of chemicals, assist in chemical processing. Organelle |
Superior and Inferior | Towards head..... towards feet |
Anterior and Posterior | Towards the front....towards the back |
Medical and Lateral | Towards the midline.....away from the midline |
Proximal and Distal | Nearest to the truck of the body.... farthest from the truck of the body |

Coronal Plane | AKA Frontal plane |
Normal reading or range of normal | Set point or setpoint range |
Several tissues working together are termed | Organ |
Smallest to largest the levels of organization of the body are | Chemical, organelle, cellular, tissue, organ, system, organism |
Molecules are | atoms combined to form larger chemical aggregates |
Hydrolysis | breaks down compounds by adding a water molecule |
Electrolytes are | called cations if they have a positive charge |
The hydrogen isotope tritium consists of | One proton and two neutorns |
Ribosomes are organelles that | Float in the cytoplasm and attach to the endoplasmic reticulmn |
Cell fibers from largest to smallest | Microtubules, intermediate filaments, microfilaments |
Compact bone contains many cylinder-shaped structural units called | Osteons |
If one side of a DNA molecule is CTAGGCTG the other side would be | GATCCGAC |
DNA base pairs | Adenine-Thymine Cytosine-Guanine |
