In: Anatomy and Physiology
Standard anatomical position is a way of describing the anatomy of an organism so that it is easy to understand what part of the body is being talked about no matter what direction the organism is facing or where its appendages/limbs are. In humans, standard anatomical position is defined as standing up straight with the body at rest.
Function of anatomical position
The purpose of standard anatomical position is to be able to clearly talk about different parts of moving organisms no matter how they are moving or what position they are in. This makes it easier to avoid confusion when discussing anatomy. In humans, standard anatomical position is with the body standing up straight and facing forward, with arms by the sides of the body and palms facing forward. The legs are straight, and the feet are slightly apart from one another and turned outward slightly. This is used as a starting point for describing the body. In animals that are quadrupedal, or walk on four legs, standard anatomical position is with all four feet on the ground so that the belly of the animal is roughly parallel with the ground
Some example
Superior-Inferior
In standard anatomical position, the head is the most superior part of the body, and the feet are the most inferior.
Medial-Lateral
Lateral describes the parts of the body that are toward the sides, while medial describes the middle of the body. If a part of the body is lateral, it can mean left lateral or right lateral
