What Are The Body Planes And Directional Terms?

How are body planes named?

The sagittal plane or lateral plane (longitudinal, anteroposterior) is a plane parallel to the sagittal suture.

It divides the body into left and right.

The coronal plane or frontal plane (vertical) divides the body into dorsal and ventral (back and front, or posterior and anterior) portions..

What plane separates the head from the neck?

Sagittal Plane: A Sagittal Plane divides the body into right/left parts [head, neck, trunk, tail].

Is dorsal a top or bottom?

The dorsal (from Latin dorsum ‘back’) surface of an organism refers to the back, or upper side, of an organism. If talking about the skull, the dorsal side is the top. The ventral (from Latin venter ‘belly’) surface refers to the front, or lower side, of an organism.

How do you remember planes of the body?

To remember it, let the name help you out: the prefix trans means “across.” Think of Transatlantic airlines flying you across the Atlantic Ocean. Alternatively, think of the horizon, which is the horizontal boundary between the earth and the sky, and you’ll remember the direction of the horizontal (transverse) plane.

How many Parasagittal planes are in the human body?

The nine divisions are part of parasagittal and two transverse planes of body-centered around the navel. These divisions are important anatomically to determine the location of the organ within the abdomen and pelvic area.

What are the major body planes?

There are three basic reference planes used in anatomy: the sagittal plane, the coronal plane, and the transverse plane.

What is a coronal section?

A coronal plane (also known as the frontal plane) is any vertical plane that divides the body into ventral and dorsal (belly and back) sections. It is one of the three main planes of the body used to describe the location of body parts in relation to each other axis.

What are the 3 types of body planes?

There are three planes commonly used; sagittal, coronal and transverse.

Why do we need directional terms?

Regions of the body are identified using terms such as “occipital” that are more precise than common words and phrases such as “the back of the head.” Directional terms such as anterior and posterior are essential for accurately describing the relative locations of body structures.

Is the elbow distal to the wrist?

The wrist joint is distal to the elbow joint. The scaphoid lies in the proximal row of carpal bones.

How many cavities does the human body have?

Humans have four body cavities: (1) the dorsal body cavity that encloses the brain and spinal cord; (2) the thoracic cavity that encloses the heart and lungs; (3) the abdominal cavity that encloses most of the digestive organs and kidneys; and (4) the pelvic cavity that encloses the bladder and reproductive organs.

What is directional position?

Directional terms describe the positions of structures relative to other structures or locations in the body. Superior or cranial – toward the head end of the body; upper (example, the hand is part of the superior extremity).

What is the anatomical term for head?

The cephalon or cephalic region refers to the head. This area is further differentiated into the cranium (skull), facies (face), frons (forehead), oculus (eye area), auris (ear), bucca (cheek), nasus (nose), oris (mouth), and mentum (chin).

What are the 3 axis of the body?

Just as there are three planes of motion, there are three axes of rotation: the anterior-posterior axis, the mediolateral axis, and the longitudinal axis.

Which directional term means lying face down?

ProneProne: With the front or ventral surface downward (lying face down), as opposed to supine. Proximal: Toward the beginning, as opposed to distal. Sagittal: A vertical plane passing through the standing body from front to back. The mid-sagittal, or median plane, splits the body into left and right halves.

What are the directional terms of the body?

Anatomical Directional TermsAnterior: In front of, front.Posterior: After, behind, following, toward the rear.Distal: Away from, farther from the origin.Proximal: Near, closer to the origin.Dorsal: Near the upper surface, toward the back.Ventral: Toward the bottom, toward the belly.Superior: Above, over.Inferior: Below, under.More items…•Jul 3, 2019

What are the 4 body planes?

The anatomical planes are four imaginary flat surfaces or planes that pass through the body in the anatomical position. They are the median plane, sagittal planes, coronal (frontal) planes and horizontal (transverse) planes (figure 2).
