- Anterior (or ventral) describes the front or direction toward the front of the body. The toes are anterior to the foot. Posterior (or dorsal) describes the back or direction toward the back of the body. The popliteus is posterior to the patella. Superior (or cranial) describes a position above or higher than another part of the body proper.

What are anatomical terms?
Directional terms such as anterior and posterior are essential for accurately describing the relative locations of body structures. Images of the body’s interior commonly align along one of three planes: the sagittal, frontal, or transverse.

Sep 30, 2019 · Like you use the cardinal directions to explain the location of certain regions (north, northwest, southeast, etc.), you use directional terms to describe the regions of the body. Here are some commonly used directional terms: Anterior. At or near the front of the body (front view) Posterior.
When you take Anatomy and Physiology, you’ll learn about the anatomical position, as well as some basic directional terms. These terms may seem complicated at first, but they are easy to learn, and I’m going to give you some tips for remembering them.
Directional Terms. With the body in anatomical position, there are specific terms to describe parts of the body with respect to each other. Please note that these terms are always used in reference to a body in anatomical position, regardless of that human body's actual position.
- Anatomical Position. To further increase precision, anatomists standardize the way in which they view the body. Just as maps are normally oriented with north at the top, the standard body “map,” or anatomical position, is that of the body standing upright, with the feet at shoulder width and parallel, toes forward.
- Regional Terms. The human body’s numerous regions have specific terms to help increase precision (see Figure 1.12). Notice that the term “brachium” or “arm” is reserved for the “upper arm” and “antebrachium” or “forearm” is used rather than “lower arm.”
- Directional Terms. Certain directional anatomical terms appear throughout this and any other anatomy textbook (Figure 1.13). These terms are essential for describing the relative locations of different body structures.
- Body Planes. A section is a two-dimensional surface of a three-dimensional structure that has been cut. Modern medical imaging devices enable clinicians to obtain “virtual sections” of living bodies.
Jun 7, 2024 · Anatomical directional terms are like the directions on a compass rose of a map. Like the directions North, South, East and West, they can be used to describe the locations of structures in relation to other structures or locations in the body.
Nov 23, 2022 · Directional terms refer to the relative locations of different body structures. 2 Essentially, they explain how close or far away different structures are from one another. Anterior and posterior are terms used to describe whether a structure is in front of or behind another.
