Anatomical Planes of the
Human Body
Anatomical Planes Defined
p.14 Fig. 1.11
 Saggital (median) Plane – lengthwise cut
of the body into right and left sides; if
passes along midline, then body is in
equal parts = median
 Transverse (horizontal) plane – cut that
divides body into superior and inferior
portions
 Coronal (frontal) plane – divides body into
anterior and posterior views.
Anterior and
Posterior
view
Anterior and Posterior Positions
 Anterior –
means towards the front
 Posterior –
opposite view of anterior;
means toward the back
Superior
and Inferior
Views
Superior and Inferior Views
Superior –
 means the body part is above
another part or is closer to the
head.
Inferior –
 means the body part is below
another part or is closer to the
feet
Medial
and
Lateral
Views
Medial and Lateral
Medial  relates to an imaginary midline dividing
the body into equal left and right halves.
Body part is medial if it is close to the
midline. (Nose is medial to the eyes)
Lateral –
 means toward the side with respect to
the imaginary midline (Ears are lateral to
the eyes)
Proximal
and Distal
Views
Proximal and Distal
Proximal –
 describes a body part that is closer to a
point of attachment than another body
part. (Elbow is proximal to the wrist)
Distal –
 opposite of proximal; particular body
part is farther from a point of attachment
than another body part. (Fingers are
distal to the wrist)
Superficial and Deep
Superficial –
situated near the surface
Deep –
parts that are more internal
Body Views
Axial Portion – head, neck, trunk
 Dorsal cavity – cranial cavity and
vertebral canal
 Ventral Cavity – Thoracic cavity,
Diaphragm, abdominopelvic cavity
Appendicular Portion – arms & legs
Body
Cavities
Lateral
View
Body Cavities
cranial cavitiy –
 houses the brain
vertebral canal –
 spinal cord and some vertebrae
Body Cavities
Thoracic cavity – Lungs and more
 Mediastinum region (separates right and
left lungs) = heart, esophagus, trachea,
and thymus
Diaphragm –
 separates the thoracic from the
abdominopelvic
Body Cavities
 abdominopelvic cavity –
 Abdominal cavity – stomach, liver,
spleen, gallbladder, kidneys, most of the
small and large intestines
 Pelvic cavity – enclosed by hip bones;
includes terminal portion of large
intestine, urinary bladder, and internal
reproductive organs.
