(32 cards)
Standard Anatomical position of the body is erect
Head facing forward, arms by the sides with palms to the front. Left and right are from the subject’s point of view, not the examiner’s
Three reference systems
Direction, Planes, Cavities, and Structural unit
Directional and positional terms
Describe the location of organs or body parts in relationship to one another.
Superior
Above, in upward direction, toward the head
Inferior
Below or in a downward direction; move toward the feet or tail
Anterior- ventral
In front of or before, the front side of the body
Posterior- dorsal

Caudal
Pertaining to the tail; inferior in position
Cephalic
Pertaining to the head; superior in position
Medial
Nearest the midline or middle
Lateral
To the side, away from the middle
Proximal
Nearest the point of attachment or near the beginning of a structure
Distal
Away from the point of attachment or far from the beginning of a structure
Planes
Describe the imaginary planes that passes through the body and dividing it into various sections.
Midsagittal planes- median plane
Vertically divides the body as it passes through the midline to form right half and left half
Transverse- horizontal plane
Any plane that divides the body into superior and inferior portions
Coronal- frontal plane
Any plane that divides the body at right angles to the midsagittal plane. They divides the body into anterior (ventral) and posterior (dorsal) portions
Cavity
Is a hollow space containing body organs
Body cavity two groups
Ventral cavity or anterior cavity
Dorsal cavity or posterior cavity
Ventral cavity- anterior cavity
Is the hollow portion of the human torso extending from the neck to the pelvis containing the heart, and the other organs of respiration, digestion, reproduction and elimination.
Ventral cavity subdivision areas
Thoracic, Abdominal and Pelvic
Thoracic cavity
The area of the chest containing the heart and the lungs.
Pericardial cavity within the Thoracic cavity
Is the space containing the heart.
Pleural cavity within the thoracic cavity
Is the space surrounding each lungs
