The proximal part of a limb is the part close to where it joins the body, while the distal part is the part furthest away. For example, the tips of our fingers are the most distal part of our arms. All of these terms are used for relative positions as well as standard anatomical position; for example, the neck is superior to the chest, ...

Which plane divides the body into dorsal and ventral sides?
The coronal plane divides the body into dorsal and ventral sides. The sagittal plane divides the body into left and right, while the transverse plane divides the body into cranial and caudal. Choice D, caudal, is not an anatomical plane.
Why are anatomical positions important?
Anatomical positions are important because they give us a frame of reference for describing the body. Similar to a compass, they give us a universal way to describe the position of an organism.

What is the difference between body position and posture?
Body “POSITIONS” and “POSTURE” are two distinct terms.#N#‘Position’ is the position of the body and body parts in relation to space. It is passive in nature and non-responsive.#N#‘Posture’ is dynamic in nature.#N#For example, someone is sitting on a chair in a sitting position. But, he/she is actually sitting in a bending posture which is a wrong posture.
How many names are there for the human body system?
Although, the body can be positioned in multiple ways, for the study purpose the human body system can be recognized under three names. These body positions are very basic positions but one needs to keep their eyes on the small details.
Is standing anatomical?
Anatomical position is standing position. But, not all standing position can be anatomical position. If a person is standing relaxed with hand on the waist and staring towards ground, cannot be anatomical position. To call a standing position truly anatomical position, here are few details we should make sure to follow.
What is the anatomical position of the human body?
The human body’s anatomical position is described as any region of the body in a definite stance—when the body is in an erect position, facing towards the observer, directed forward, and feet flat on the ground. The arms are at the side of the body, palms forward and feet together.
Why use anatomical directional terms?
Anatomical directional terms are used to point out definite anatomical structures based on someone’s perspective. It is better to have a specific pair of terms to allow you to easily find an organ with respect to the location or position of another. It is a language commonly used to navigate yourself through anatomy and body structures easily.

The supine position, which is also referred to as Dorsal Decubitus, is when the anatomical position of the body is positioned face up. It is defined by horizontally lying down with the torso and face facing upwards.
Why is it important to standardize the position of the organism's body?
In studying Anatomy and Physiology, it is important to standardize the position of the organism’s body to avoid disorientation and confusion. Every other organism is unique and can take on different positions that might change the placement of its internal and external organs. Descriptions are standardized even when the organism’s limbs are in a different position, thus providing a more accurate location of the organs when studying the anatomies of 2 different representatives of the same species.

Anatomical position for a human is when the human stands up, faces forward, has arms extended, and has palms facing out.
When anatomists or health professionals identify the location of a structure in the human body, do they do so?
When anatomists or health professionals identify the location of a structure in the human body, they do so in reference to a body in anatomical position. That is, they figure out the location based on the assumption that the body is starting out in anatomical position.
What is the difference between anatomical right and anatomical left?
When referencing a structure that is on one side of the body or the other, we use the terms “anatomical right” and “anatomical left.” Anatomical right means that the structure is on the side that a person in anatomical position would consider their right-hand side (not necessarily on the right of the viewer) and anatomical left means that the structure is the side that a person in anatomical position would consider their left-hand side (which likewise is not necessarily the left side of the viewer.)
What is the difference between medial and lateral?
A structure that medial to another is closer to the midline of the body’s trunk. A feature that is lateral to another is farther away from the midline of the trunk.
What is superior to inferior?
Superior/Inferior –Equivalent to above and below when moving along the long axis of a body in anatomical position. The structure that is superior to another is above the second structure when the body is in anatomical position. A feature that is inferior to another is below the second feature when the body is in anatomical position.
How to view the interior of a body?
To view the interior of a body, we expose the organs and structures that are visible when that body is cut open along one of four commonly used sectional planes. These planes are the different directions a body is cut to reveal different views of its internal structures.
What does "proximal" mean in anatomy?
A feature that is proximal to something else is closer to the limb’s point of attachment to the trunk. A structure that is distal to something else is farther away from the limb’s point of attachment. Less precisely but still occasionally used in the trunk of the body itself to indicate whether something is closer to (prox imal) or farther away from (distal) something else.

Anatomical Position Definition
Function of Standard 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 pal…
Relative Locations of The Body
- This diagram depicts the body in standard anatomical position and uses positional labels. Let’s take a more detailed look at the labels used for different parts of the anatomy. They are regarded as axes because they are used to describe how near or far a body part is from an end of the organism.
Planes of The Body
- There are three main planes that transect, or divide, the human body into sections to make it easier to describe the locations of body parts and movements. They are the sagittal plane, the coronal plane, and the transverse plane. The sagittal plane runs down the center of the body and divides the body into left and right sides. The coronal plane divides the body into dorsal and vent…
