A description of any region or part of, the body in a specific stance is called the, anatomical position., In the anatomical position, the body is upright, directly, facing the observer, feet flat and directed forward., The upper limbs are at the body’s sides with the palms, facing forward., , www.visiblebody.com

If the body is lying face up, it is in the, supine position., www.visiblebody.com, , If the body is lying face down, it is in the, prone position.

Directional terms are words used to, describe the position of one body relative to, another., Many directional terms are grouped in pairs that have, opposite meanings (ex: anterior-posterior), or are grouped, together to have combined meanings (ex: anterosuperior)., , www.visiblebody.com

When we study the parts of the body,, we also study their relativity to planes., Planes are imaginary flat surfaces that pass, through parts of the body., We also study parts of the body in sections, which are, cuts along a certain plane., , www.visiblebody.com
