| anatomy | the study of the structure of an organism and the relationships of its parts |
| appendicular | refers to the upper and lower extremeties |
| atrophy | wasting away of tissue |
| axial | refers to the head, neck, and torso |

| abdominal cavity | single cavity containing the abdominal and pelvic organs |
| cranial cavity | space inside the skull that contains the brain |
| dorsal cavity | includes the cranial and spinal cavity |
| mediastinum cavity | a subdivision in the midportion of the thoracic cavity |
| pelvic cavity | the lower portion of the ventral cavity |
| pleural cavity | a subdivision of the thoracic cavity |
| spinal cavity | the space inside the spinal column through which the spinal cord passes |
| thoracic cavity | pertaining to the chest area of the body |
| ventral cavity | organ containing space in the anteroir trunk of the body that includes the thoracic and abdominopelvic cavities |
| control center | |
| diaphragm | membrane or partition that seperates the thoracic and abdominal cavities |
| superior | higher |
| inferior | lower |
| anterior | front |
| posterior | back |
| ventral | front |

| medial | toward the midline of the body |
| lateral | further from the midline of the body |
| proximal | located nearest the center of the body |
| distal | toward the end of a structure |
| superficial | toward the surface of the body |
| deep | farther away from the body's surface |
| dissection | cutting technique used to seperate body parts for study |
| effector | responding organ |
| experimentation | performing an experiment |
| feedback loop | a complex control network classified into positive and negative |
| homeostasis | relative uniformity of the normal body's internal environment |
| hypothesis | a proposed explaination of an observed phenomenon |

| chemical | the simplest structure in a living organism |
| cellular | the smallest living unit in an organism |
| tissue | group of similar cells that perform a common function |
| organ | group of several tissue types that performs a special function |
| system | group of organs arranged so that the group can perform a more complex function than any one organ can perform alone |
| physiology | the study of body function |
| sagittal | a plane that divides the body into right and left halves longitudinally |
| midsagittal | a cut or plane that divides the body or any of its parts into two EQUAL halves |
| frontal | lengthwise plane running from side to side, dividing the body into anterior and posterior portions |
| transverse | a plane that divides the body into upper and lower halves |
| positive feedback loop | a control system that feeds back information to the control center causes the level of a variable to be pushed further in the direction of the original deviation |
| prone | lying face down |
| scientific method | any logical and systematic approach to discovering principles of nature, often involving testing |
| sensor | responding sensor in a feedback loop |
| supine | lying face up |
| theory | an explaination of a scientific principle that has been tested experimentally and found to be true |
