Definitions
|
Frontal or coronal plane (“crown”)
|
v It
is perpendicular to median plane.
v Divides
the whole body into the front and back halves of body.
|
Transverse
|
v Divide
the body into upper (superior) and lower (inferior) parts
|
Sagittal
|
v It

v Mid-sagittal
plan (median plane), pass through midline and divide body into left and right
parts.
v Parasagittal,
off to one side and divide body into unequal right and left parts
