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 |
