The term we are now going to analyze is composed of two words whose etymological origin is found in ancient languages. Thus, the first word, position, we can determine that it comes from Latin and specifically from the concept positio which is the result of the sum of positus which can be translated as “post” and suffix -tion which is defined as "putting action".

For its part, the second term, anatomical, has its aforementioned origin in the Greek where we can see that it is created from the union of several lexical components: the prefix Ana- which is equivalent to "up", the verb take which is synonymous with "cut" and the suffix -ico whose meaning is "relative to".

A position it is the bearing, the mood or the ways of someone or something. It may be a particular provision or situation. Anatomical , meanwhile, is what is associated with the anatomy (the analysis of the structure, state and links of the different body parts).

The anatomic position , therefore, it has to do with the spatial references that make it possible to describe how the woven , the organs and the systems of the human body.

The study begins with the body in what is known as standard anatomical position . The person he must stand, with his head and neck erect, his arms on both sides of the body (extended towards the floor and with the palms of his hands turned forward), and his gaze towards the front. The legs have to be extended and slightly apart, with the feet and ankles also extended.

This same standard anatomical position, if the body is located on a dissection table, implies that what you previously observed forward happens to look up, while what you observed back, is currently looking down.

In addition to the aforementioned we can establish that there are a number of anatomical positions that are considered as fundamental or more important. Among them is, for example, the position of decubitus which is the one that is defined because it means that the person is lying down. It also has three modalities: active supine that is when it is on its back; ventral that is when it is upside down and on the belly; and the active side which is the one that takes place when it is supported on one side.

In the same way, in addition to the decubitus position, we find other anatomical positions such as Fowler's, semi-sitting and knees bent or stretched; that of Sims, which is characterized as a mixture of the aforementioned ventral and active lateral; And the Mohammedan.

The anatomical position can be studied according to three axes : he vertical axis (from head to toe), the transverse axis (from side to side) and the anteroposterior axis (from front to back).

The main anatomical planes, then, are the middle plane (which divides the body into two parts: left and right), the frontal planes (separate the body in anterior and posterior), the axial planes (oriented horizontally), the sagittal planes (perpendicular to the front) and oblique planes (which divide the body in a direction that is not parallel to the rest of the planes).
