In this article, we will discuss Concepts of Human Anatomy: Body Part Regions and Body Planes. So, let’s get started.
Body Part Regions
The body can generally be described to have areas of:
Axial Body Part: It is the part of the body near the axis of the body. This includes head, neck, thorax (chest), abdomen and pelvis.
Appendicular Body Part: It is the part of the body out of the axis line. This includes upper and lower extremities. It is customary to subdivide the abdominal area into nine regions or more easily into four quadrants.
Regions: Right hypochondriac region, Epigastric region, Left hypochondriac region, Right lumbar region, umbilical region, Left lumbar region, Right iliac region, Hypogastric region, Left iliac region.
Quadrants: Right upper quadrant, Left upper quadrant, Right lower quadrant, Left lower quadrant.
Body Planes
Body planes are imaginary surfaces or planes lines that divide the body in to sections. This helps for further identification of specific areas.
Sagittal plane
- divides the body into right and left half
- Mid sagittal plane: divides the body into equal left and right halves
- Para sagittal plane: divides body into unequal left and right
Frontal plane: divides the body into asymmetrical anterior and posterior sections
Transverse plane: divides the body into upper and lower body section.
Oblique plane: divides the body obliquely into upper and lower section.
