Planes and Positions Most A&P courses, before delving into the good stuff, teach positions and planes. We’ve put together a quick guide to help you better understand them. A description of any region or part of the body in a specific stance is called the anatomical position. In the anatomical position, the body is upright, directly facing the observer, feet flat and directed forward. The upper limbs are at the body’s sides with the palms facing forward. www.visiblebody.com  If the body is lying face up, it is in the If the body is lying face down, it is in the supine position. prone position. www.visiblebody.com  Directional terms are words used to describe the position of one body relative to another. Many directional terms are grouped in pairs that have opposite meanings (ex: anterior-posterior), or are grouped together to have combined meanings (ex: anterosuperior). www.visiblebody.com  Anterior view: At or near the front Posterior view: At or near the back of the body. of the body. www.visiblebody.com  Midline: the imaginary line that divides the body into right and left halves. Medial: Nearer to midline Lateral: Away from midline www.visiblebody.com Superior view: Situated toward the head and further away from the feet; the upper part of a structure. www.visiblebody.com  Inferior view: Situated nearer to the feet than the head; the lower part of a structure. www.visiblebody.com  Deep Superficial Away from the surface Close to the surface of the body of the body www.visiblebody.com  Proximal Nearer to the origination of a structure. Distal Farther from the origination of a structure. www.visiblebody.com  When we study the parts of the body, we also study their relativity to planes. Planes are imaginary flat surfaces that pass through parts of the body. We also study parts of the body in sections, which are cuts along a certain plane. www.visiblebody.com Frontal (coronal) plane: Divides the body into front and back portions. www.visiblebody.com  Tranverse plane: Divides the body into superior (upper) and inferior (lower) portions. www.visiblebody.com  Oblique plane: Passes through a structure or the entire body at an angle. www.visiblebody.com Sagittal plane: Divides a structure or the body vertically into right or left portions. www.visiblebody.com Review and Practice Okay, we’ve thrown a lot of terms at you over the course of this eBook. Time to see what you remember. Positions and directionals: Commonly used planes: Anterior: At or near the front of the body. Frontal (or coronal): Divides the body into anterior (front) Posterior: At or near the back of the body. and posterior (back) portions. Midline: Imaginary vertical line dividing the body equally. Transverse (or horizontal): Divides the body into superior Superior: Toward the head, upper part of a structure. (upper) and inferior (lower) portions. Inferior: Away from the head, lower part of a structure. Sagittal: Divides the body vertically into right and left sides. Lateral: Farther from midline. Midsagittal: Divides the body vertically into equal right and Medial: Nearer to midline. left sides. Proximal: Nearer to the origination of a structure. Parasagittal: Divides the body vertically into unequal right Distal: Farther from the origination of a structure. and left sides. Superficial: Close to the surface of the body. Oblique: Passes through the body at an angle. Deep: Away from the surface of the body.  This is a _______ view. This is a _______ view.
