[44], Some elongated protists have distinctive ends of the body. In such organisms, only terms such as superficial and deep, or sometimes proximal and distal, are usefully descriptive. [68] Eyes are labelled according to their position as anterior and posterior lateral eyes (ALE) and (PLE); and anterior and posterior median eyes (AME) and (PME). "Lateral", "dorsal", and "ventral" have no meaning in such organisms, and all can be replaced by the generic term peripheral (from Ancient Greek περιφέρεια 'circumference'). [46][47] For example, the terms "distal" and "proximal" are also redefined to mean the distance away or close to the dental arch, and "medial" and "lateral" are used to refer to the closeness to the midline of the dental arch. The palmar fascia is palmar to the tendons of muscles which flex the fingers, and the dorsal venous arch is so named because it is on the dorsal side of the foot. The most amazing human being on this earth. In organisms with a changeable shape, such as amoeboid organisms, most directional terms are meaningless, since the shape of the organism is not constant and no distinct axes are fixed. Definition of the anatomical direction term superior as used in anatomy biology kinesiology and medicine with examples of use of the term. Anatomical lines are used to describe anatomical location. [8] To do this, distinct ends of an organism are chosen, and the axis is named according to those directions. “Relations of the aorta, trachea, esophagus and other heart structures” By ZooFari (CC BY-SA 3.0) via Commons Wikimedia, Lakna, a graduate in Molecular Biology & Biochemistry, is a Molecular Biologist and has a broad and keen interest in the discovery of nature related things, What is the Difference Between Superior and Inferior in Anatomy. 1. 1. 2. 5. They only live because everyone knows they are superior. Therefore, the term ‘superior’ can also describe structures towards the head. These terms are used to avoid confusion when describing the median surface of the hand and what is the "anterior" or "posterior" surface – "anterior" can be used to describe the palm of the hand, and "posterior" can be used to describe the back of the hand and arm.

Therefore, the head is the most superior anatomical structure in humans. Thus, the "rostrocaudal axis" refers to a C shape (see image). Unique terms are used to describe animals without a backbone (invertebrates), because of their wide variety of shapes and symmetry. Similarly, in the forearm, for clarity, the sides are named after the bones. In radiology, an X-ray image may be said to be "anteroposterior", indicating that the beam of X-rays passes from their source to patient's anterior body wall through the body to exit through posterior body wall. Anatomy Next provides anatomy learning tools for students and teachers For example, in the anatomical position, the most superior part of the human body is the head and the most inferior is the feet. [34] For example, the arm is peripheral to the body. Similarly, the term ‘inferior’ can describe the structures towards the feet in the human body.

These terms are generally preferred in veterinary medicine and not used as often in human medicine. Gross anatomy Origin and course. Additionally, in other animals, this term can describe the structures located towards the end of the body. However, some biradially symmetrical comb jellies do have distinct "tentacular" and "pharyngeal" axes[66] and are thus anatomically equivalent to bilaterally symmetrical animals.

Reversal of SMA/SMV relationship is classically associated with intestinal malrotation, although distally (>6 cm from origin) this may be a normal finding 6. This is because although teeth may be aligned with their main axes within the jaw, some different relationships require special terminology as well; for example, teeth also can be rotated, and in such contexts terms like "anterior" or "lateral" become ambiguous. For example, the top of a dog's paw is its dorsal surface; the underside, either the palmar (on the forelimb) or the plantar (on the hindlimb) surface. The head is superior to the neck; the umbilicus is inferior to the sternum. DOI:10.15347/wjm/2014.010. 1.

Volar can also be used to refer to the underside of the palm or sole, which are themselves also sometimes used to describe location as palmar and plantar. Superior means ‘higher’, inferior means ‘lower’. Usually such organisms are planktonic (free-swimming) protists, and are nearly always viewed on microscope slides, where they appear essentially two-dimensional. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. This helps avoid confusion in terminology when referring to the same organism in different postures. Similarly, a perpendicular transverse axis can be defined by points on opposite sides of the organism. What is the meaning of anatomy? 3. Another word for superior. In such organisms, the end with a mouth (or equivalent structure, such as the cytostome in Paramecium or Stentor), or the end that usually points in the direction of the organism's locomotion (such as the end with the flagellum in Euglena), is normally designated as the anterior end.

Organisms that are attached to a substrate, such as sponges, animal-like protists also have distinctive ends. 3. [44] For this reason, the end of the organism with the mouth is referred to as the oral end (from Latin ōrālis 'of the mouth'),[64] and the opposite surface is the aboral end (from Latin ab- 'away from').[65]. Also, another difference between superior and inferior is that the term ‘superior’ can be used to describe the anatomical structures located towards the head while the term ‘inferior’ can be used to describe the anatomical structures located towards the feet or end of the body.

Similarly, in the lower leg, structures near the tibia (shinbone) are tibial and structures near the fibula are fibular (or peroneal). Blausen.com staff (2014). Terms include: Different terms are used because of different body plans in animals, whether animals stand on one or two legs, and whether an animal is symmetrical or not, as discussed above. All procedures were videotaped. Because the sacrum and coccyx are fused, they are not often used to provide the location. The long or longitudinal axis is defined by points at the opposite ends of the organism. Superior and inferior are two anatomical terms that describe the location of different structures of the body.
