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
