Prelims Flashcards
is a term that describes central ray angles or relationships between both parts often are related to imaginary planes that pass through the body in the anatomic position
body planes
is a reference position that defines specific surfaces and planes of the body
anatomic position
is any longitudinal plane that divides the body into right and left portion
sagittal plane
is the plane which divides the body into equal right and left halves
median/midsagittal plane
is any longitudinal plane that divides the body into anterior and posterior portion
coronal plane
is any transverse plane that passes through the body at right angles to a longitudinal plane dividing the body into superior and inferior portion
horizontal plane
is any plane that can pass through a body part at any angles between three planes
oblique plane
is any plane that transects the pelvis at the top of the iliac crests at the level of the 4th spinous process
interiliac plane
a plane that is formed by the biting surfaces of the upper and lower teeth with the jaws closed
occlusal plane

the common variations in the shape of human body
body habitus
it determines the shape, size, position of the thoracic and abdominal cavities
body habitus
50% of population has this body habitus
sthenic
35% of population has this body habitus
hyposthenic
10% of population has this body habitus
asthenic
5% of population has this body habitus
hypersthenic
the organs and characteristics for this habitus are INTERMEDIATE BETWEEN THE STHENIC AND ASTHENIC body habitus types, this habitus is the most difficult to classify
hyposthenic
this body habitus is the massive type
hypersthenic
toward the front
anterior
toward the back
posterior
toward the head
superior
toward the feet
inferior
towards the median plane/near the middle of the body
medial
away from the median plane
lateral
parts closer/near the source or beginning
proximal
parts away from the source or beginning
distal
towards the head end
cephalad, cephalic, cranially
towards the feet or tail end
caudal, caudad
