Standard anatomical terms of location are used to describe unambiguously the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on.
The three anatomical planes of the body: the sagittal, transverse (or horizontal), frontal planes. Anatomy is often described in planes, referring to two-dimensional sections of the body. A section is a two-dimensional surface of a three-dimensional structure that has been cut. A plane is an imaginary two-dimensional surface that passes through ...
Proximal The surfaces of teeth that normally lie adjacent to another tooth. Proximal includes both mesial and distal, such as when referring to the proximal surfaces of teeth. [1] Quadrant Dental quadrants The dentition is divided into four quarters. The two dental arches form an oval, which is divided into quadrants which are numbered from 1 ...
The standard anatomical position, or standard anatomical model, is the scientifically agreed upon reference position for anatomical location terms. Standard anatomical positions are used to standardise the position of appendages of animals with respect to the main body of the organism. In medical disciplines, all references to a location on or ...
A malleolus is the bony prominence on each side of the human ankle.. Each leg is supported by two bones, the tibia on the inner side (medial) of the leg and the fibula on the outer side (lateral) of the leg.
The anatomical axes of orientation of the human brain are at odds with the anatomical axes of the human body in the standard anatomical position. Red axis shows how the head bent forward as the back pointed upwards: c: Caudal r: Rostral Yellow axes show the conventions for naming directions in the brain itself: c: Caudal (though not tail ...
The tibia, located medially, bears most of the body's weight, while the fibula, positioned laterally, is smaller and supports leg structure. Further down the leg are the metatarsal bones, found near the distal end of the hindlimb. These bones are positioned proximal to the toe bones, or phalanges, providing support and structure in the foot.
Definition Etymologic memory aid; apophysis: Any of various processes or protuberances on a bone. apo-+ physis, "outward from the growth part; outgrowth" diaphysis: The long, relatively straight main body of a long bone; region of primary ossification. Also known as the shaft. dia-+ physis, "between the growth parts" epiphysis
