| Question |
Answer |
| abdominopelvic quadrants |
health professionals divide the abdomen into four areas to help locate specific organs |
| abdominopelvic regions |
anatomists have divided the abdomen into nine regions to identify the location of organs |
| anatomical position |
the reference position for the body, which gives meaning to directional terms |
| 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 |
| dorsal |
back |
| 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 |
| negative feedback loop |
control system where information feeding back to the control center causes the level of a variable to be changed in the direction opposite to that of the initial stimulus |
| 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 |
| law |
a scientific law is a theory, or explaination of a scientific principle, with an extraordinarily high degree of acceptance |
