Body Structure Flashcards
Toward the front of the body, organ, or structure
anterior
anter: anterior, front
-ior: pertaining to
Pertaining to the front and back of the body or passing from the front to the back of the body
anteroposterior
Pertaining to below, lower, or toward the tail
inferior
Process of using a moving device or a sweeping beam of radiation to produce images of an internal area, organ, or tissue of the body
scan
molecules combine to form cells, the basic structural and functional units of the body
cellular level
groups of cells that work together to perform a specialized function
tissue level
structures that are composed of two or more different types of tissue; they have specific functions and usually have recognizable shape
organ level
related organs with a common function; also called organ-system level
sytem level
collection of body systems that makes up the most complex level: a living human being. All parts of the human body functioning together constitute the total organism.
organism level
the standard reference position of the body
anatomical position
the person stands erect, the eyes look straight ahead, the arms are at the sides of the body with the palms of the hand turned forward, and the feet are parallel to one another and flat on the floor.
anatomical position
the relationship of one body part to another in reference to the anatomical position
directional terms
Movement toward the midline of the body
ADDuctive movement
you are adding a part to the body
away from the midline of the body
abductive movement
Above or higher; toward the head
Superior (cephalic, cranial)
Below or lower; toward the tail
inferior (cadual)
Front of the body; toward the front
anterior (ventral)
Back of the body; toward the back
Posterior (dorsal)
Pertaining to the middle; toward the midline
medial
Pertaining to the side; toward the side
lateral
Outside, exterior to
external
Within, interior to
Internal
Toward or on the surface
superficial
Away from the surface
deep
Near the point of attachment to the trunk or a structure
proximal
Farther from the point of attachment to the trunk or a structure
distal
Pertaining to the outer wall of a cavity
perietal
Pertaining to the organs within a cavity
visceral
vertical plane that passes through the midline of the body and divides the body or organ into equal right and left sides; also called midsagittal plane
median plane
plane that divides the body into anterior (front) and posterior (back) portions; also called coronal plane
frontal plane
plane that separates the body into superior (upper) and inferior (lower) portions; also called transverse plane
horizontal plane
hollow spaces within the body that help protect, separate, and support internal organs.
body cavities
what are the two main body cavities
dorsal (back of the body)
ventral (front of the body)
