What is anatomical position?
|
-arms out, palms slightly forward
- toes forward, feet shoulder width apart |

Superficial Vs. Deep
|
Superficial and deep. Superficial refers to structures nearer the skin, and deep to structures further away from the skin; these are relative terms. They should be used instead of the colloquial "on top of" (superficial to) or "underneath" (deep to).
|
|
|
Medial Vs. Lateral
|
Medial and lateral. Medial means nearer the midline of the body and lateral means further from the midline; these are relative terms. They may also refer to the midline and "sides" of a major organ. The "outer" surface of a limb is the lateral surface and the "inner" the medial.
|
|
|
Proximal Vs. Distal
|
Proximal and distal. Proximal refers to the end of a structure nearest a major point of reference and distal to the end furthest from a point of reference. The point of reference is usually the origin of a structure (such as a limb) or the ventral midline of the body. Proximal and distal are relative terms. These terms are correctly used to describe relative positions of structures in the limbs.

|
|
Superior Vs. inferior.
|
Superior and inferior. These terms are the equivalents of cranial and caudal in Homo. Superior means toward the head and inferior toward the feet. These terms are not used for quadrupeds.
|
|
|
Dorsal (posterior) Vs. ventral (anterior).
|
Dorsal and ventral. Dorsal refers to the back of an organism and ventral to the belly.
|
|
|
Cranial Vs. caudal
|
Cranial refers to the head end and caudal to the tail end.

What is A sagittal plane?
|
A sagittal plane divides the body into right and left parts. A median sagittal plane divides the body into equal right and left halves. para sagittal: divides the body into unequal left and right portions
|
|
|
What is A frontal (or coronal) plane?
|
A frontal (or coronal) plane passes from right to left and divides the body into dorsal and ventral parts.
|
|
|
What is a transverse plane?
|
A transverse plane (or cross section) passes perpendicular to the long axis of the body (or of a limb).
