Frontal or Coronal Plane: Features and When Used

He frontal plane or coronal is that which divides the human body anatomically into two halves, to facilitate its study and understanding of the position and location of organs and systems. From this division an anterior or ventral half is generated, and a posterior or dorsal half.

To fully understand what is the coronal plane or frontal plane in the human body, it is necessary to determine the anatomical position of a body. An individual is in a neutral anatomical position when standing, with the eyes facing forward and the arms along the sides of the body.

Frontal or coronal plane

In addition, the palms of your hands are placed forward, the legs are together and the knees are straight. On the other hand, the feet point slightly outwards. The ventral section refers to the front or front of the body, while the dorsal section corresponds to the back or back of the body.

The coronal plane allows to establish the descriptive positional terms necessary to indicate the regions and anatomical characteristics of a body, as well as to determine the type of movement according to the central imaginary line.

Main characteristics

The coronal plane belongs to the set of the longitudinal planes of the human anatomy, it is clearly identified by the following characteristics:

- Imaginary line that cuts both shoulders of the body.

- It is parallel to the frontal suture of the skull.

- Go through the cranial suture.

- It forms a right angle with the sagittal plane.

- There are movements that are made to one side or the other.

- The observation of the movements in this plane is done from the previous or later view of the same.

When is it used?

It is used to accurately determine the anatomical location of the parts of the body in relation to others.

Medical imaging techniques - such as ultrasound, computed tomography, magnetic resonance imaging or PET scans - are one of the main applications in which the use of anatomical planes is necessary.

In body

Not only does it allow us to locate the position of the body parts, but it also allows us to determine the way in which the body moves.

In this case, the movements in the frontal plane are identified by making a central imaginary line observing the movement: if the movement moves away from the central line, we speak of abduction; in the case of movement towards the center of the imaginary line, it is called adduction.

In the brain

The frontal plane, as well as in the body, divides the brain into an anterior and a posterior section. It is created by cutting the brain parallel to the longitudinal axis of the body and perpendicular to the ground; that is, in a vertical position in a person in a neutral anatomical position.

The brain has a three-dimensional structure; that means that each part of it is located in the XYZ plane. The relative position and direction of brain structures are described with special words. For example, we can say that the frontal lobe is"rostral"to the occipital lobe.

As a result of the determination of the anatomical planes, the basic principles for the clear identification of the parts of the human body, as well as the movements of it, are derived. From there comes the importance of its study as a fundamental basis in human anatomy courses.
