| abdominal cavity | The cavity containing the abdominal organs |
| abdominopelvic quadrants (4) | four subdivisions of the abdomen determined by two imaginary lines dividing through the belly button. One vertical and one horizontal. Uses- medical professionals use these to help locate specific internal organs. |
| abdominopelvic regions (9) | Nine subdivisions of the abdomen determine by 4 imaginary lines configured ina tic-tac-toe pattern. Anatomists use these named regions to identify the locations of specific internal organs |
| appendicular | Upper and lower extremities of the body. (arms and legs) |
| axial | Head, neck and torso or trunk of the body |
| cavities | Hollow place or space in the body |
| control center | A part of the homeostatic feedback loop that puts together preprogrammed information with actual sensed information about a physiological varibale and then sends out a signal to an effecter to change the variable. |
| diaphragm | Mambrane that separates the thoracic cavity from the abdominopelvic cavity. |
| effector | Responding organ in a feedback loop |
| epigastric region | top middle region when using the abdominopelvic regions |
| feedback loop | A higly complex communication network. Can be either postive or negative. Negative feedback loops are the most important and popular form of homeostatic control |
| homeostasis | relative uniformity of the normal body's internal enviornment |
| hypochondriac region | Can either be left or right in the top row of the abdominopelvic regions |
| hypogastic region | The bottom middle section in the abdominopelvic regions |
| iliac region | can either be left or right in the bottom row of the abdominopelvic regions |
| lumbar region | Can either be left or right in the middle row of the abdomiopelvic regions |
| mediastinum | A subdivision in the midportion of the thoracic cavity |
| negative feedback loop | homeostatic control system in which information feeding back to the control center causes the level of the varibale to be changed in the direction opposite to that of the intiial stimulus. |
| pelvic cavity | The lower portion of the ventral cavity |
| Pleural Cavity | A cavity in the thoracic cavity |
| positive feedback loop | homeostatic control system in which information feeding back to the control center causes the level of the varibale to be changed in the direction same to that of the intiial stimulus. It amplifies the original signal to make it stronger |
| sensor | Part of the homeostatic feedback loop that senses changes in physiological varibale that is regulated in the feedback loop |
| spinal cavity | The space inside the spinal colummn through which the spinal cord runs |
| thoracic cavity | Organ containing space inside the ribcage or chest of the body that includes the mediastinum and left and right pleural cavities. |
| atrophy | Wasting away of tissue decreasing its size |
