ANATOMICAL TERMS PowerPoint Presentation free download Biology Diagrams Descriptions of directional terms include: a) superior (head) and inferior (caudal), b) anterior and posterior, c) lateral and medial, d) deep and superficial, e) proximal and distal, and f) dorsal and ventral. Directional terms provide comparison of anatomical position by comparing the locations of different structures in the body.
Superficial describes a position closer to the surface of the body. The skin is superficial to the bones. Deep describes a position farther from the surface of the body. The brain is deep to the skull. Figure 1.4.2 - Directional Terms Applied to the Human Body: Paired directional terms are shown as applied to the human body. Body Planes Superficial refers to a structure that is closer to the surface of the body. Deep refers to a structure that is farther away from the body's surface. For example, I could say my skin is superficial to my biceps brachii muscle. Or, I could compare the depth of two muscles. For example, the brachialis muscle is deep to (underneath) the biceps
Anatomical Position and Directional Terms Biology Diagrams
For example, a superficial bruise may only require rest, while deeper tissue injuries might demand physical therapy or medical intervention. Conclusion. In the world of anatomy, the terms 'superficial' and 'deep' have implications that stretch beyond mere descriptions. Understanding the difference between superficial and deep has practical implications. For instance, when a healthcare provider is talking about an injury say a bruise they might say it's superficial if it's just under the skin. But if you're told it's a deep tissue injury, well, that sounds a lot more serious! A Personal Anecdote Deep (or internal) means the opposite: away from the outside of the body. A deep wound is going to penetrate far below the surface of the skin! The liver is deep to the rib cage. The skin is superficial to the liver. The muscles are deep to the skin, and the skin is superficial to the kidneys.
Superficial vs Deep. The next pair of directional terms is superficial and deep. Superficial. If we move closer to the surface of the body, then we are moving superficial. Therefore, superficial is defined as "closer to the surface". "Superficial" and "Surface" both start with the letter "S" which makes it easy to remember. Deep is a directional term that describes the position of a structure as away from the surface of the body. It also denotes a structure that is further away from the surface of the body when compared with another structure. The opposite term of deep is superficial, which pertains to a structure that is closer to the surface of the body.. For example, the muscles are found deep to the surface
