| abdominopelvic cavity | A combination of all the organs that belong in the abdominal cavity and the pelvic cavity. |
| 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 |
| anatomical position | the standard nuetral reference position for the body used to describe sites or motions of various body parts; gives the directional terms meaning, |
| anatomy | The study of structure of an organism and the relationships of its parts |
| anterior | Front (ventral) |
| appendicular | Upper and lower extremities of the body. (arms and legs) |
| axial | Head, neck and torso or trunk of the body |
| Ventral cavities | Cavities that run along the front side of an organism. In humans they include the thoracic cavity, and the abdominopelvic cavity. |
| cell | The basic structural part of the body consisting of a nucleus surrounded by sytoplasma nd enclosed by a membrane. |
| chemical level | The level of the bodys organization that includes atoms and molecules |
| 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. |
| cranial cavity | The dorsal body cavity that contains the brain |
| deep | further away from the bodies surface |
| disease | A significant abnormality in the body's structure and function that disrupts a person's function or physical, mental or social well being. |
| Dorsal Cavity | Cavities that run along the back side of an organism. In humans they include the spinal cavity and the cranial cavity. |
| distal | toward to end of something |
| effector | Responding organ in a feedback loop |
| 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 |
| frontal plane | Lengthwise plane running from side to side, dividing the body into anterior and posterior portions |
| homeostasis | relative uniformity of the normal body's internal enviornment |
| inferior | Lower |
| lateral | Toward the side |
| medial | Toward the middle |
| 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. |
| organization (structural levels) | ( Going from small to large) cell-> Tissue-> Organ-> Organ System-> Organism |
| physiology | The study of body structure |
| 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 |
| posterior | To the back (dorsal) |
| prone | Used to describe the body laying in a horizontal positon facing downward |
| proximal | Next to or near |
| sagittal plane | Longitudinal- A strait cut up and down |
| 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 |
| superficial | Closer to the surface |
| superior | Higher (cranial) |
| supine | The body lying in a horizontal position facing upwards |
| Organ system | Group of organs working goether to perfom a complex function that no one organ can perfom by itself. |
| thoracic cavity | Organ containing space inside the ribcage or chest of the body that includes the mediastinum and left and right pleural cavities. |
| tissue | a group of similar cells that perform a common function |
| transverse plane | A flat cut though the body that is hoprizontal or crosswise and thus divides the body into upper and lower portions |
| Organ | A group of tissues working together to complete a specific function |
| atrophy | Wasting away of tissue decreasing its size |
| pathology | The scientific study of disease |
