- health professionals divide the abdomen (through the navel) into four areas to help locate specific regions
- abdominal quadrants
- anatomists have divided the abdomen into nine regions to identifu the location of organs.
- abdominiopelvic regions
- the reference posion for the body, which gives meaning to directional tems.
- anatomical position
- the study of the structure of an organism and the relationships of its parts.
- anatomy
- wasting away of tissue; decrease in size of a part; sometimes refered to as the disuse _____.
- atrophy
- the cavity containing the abdominal organs.
- abdominal cavity
- space inside the skull that contains the brain.
- cranial cavity
- the lower protion of the ventral cavity; the distal portion of the abdominopelvic cavity.
- pelvic cavity
- a subdivision of the thorax
- pleural cavity
- the space inside the spinal column through which the spinal cord passes
- spinal cavity
- higher,opposite of interior
- superior
- lower; opposite of superior
- inferior
- front or ventral; opposite of posterior or dorsal
- anterior
- behind; opposite of anterior
- prosterior
- of or near the belly;in humans, front or anterior; opposite of dorsal or posterior
- ventral
- referring to the back; opposite of ventral; in humans, the posterior is dorsal
- dorsal
- of or toward the middle; opposite of lateral
- medial
- of or toward the side; opposite of medial
- lateral
- next or nearest; located nearest the center of the body or the point of attachment of a structure
- proximal
- toward the end of a structure; opposite of proximal
- distal
- near the body surface
- superficial
- farther away from the body's surface
- deep
- performing an experiment, which is usually a test of a tentative explanation of nature called a hypothesis
- experimentation
- a highly complex and integrated communication control network, classified as negative or positive; negative feedback loops are the most important and most numerous homeostatic control mechanisms.
- feedback control loop
- relative uniformity of the normal body's internal environment
- homeostasis
- a proposed explanation of an observed phenomenon
- hyposthsis
- a subdivision in the midportion of the thoracic cavity
- mediastinum
- the study of body function
- physiology
- longitudinal; like an arrow
- saggital
- a cut or plane that divides the body or any of its parts into two equal halves
- midsaggital
- lengthplane running from side to side, dividing the body into anterior and posterior portions
- frontal
- used to describe the body lying in a horizontal position facing downward
- prone
- used to describe the body lying in a horizontal position facing upward
- supine
- an explanation of a scientific priciple that has been tested experimentally and found to be true
- theory
