opposite of ventral

An indefinite number of triads of mutually perpendicular axes could be defined, but any such choice of axes would be useless, as nothing would distinguish a chosen triad from any others. Varus (from Latin 'bow-legged') and valgus (from Latin 'knock-kneed') are terms used to describe a state in which a part further away is abnormally placed towards (varus) or away from (valgus) the midline.[30]. Dorsal vs Ventral • Dorsal is the backside while ventral is the opposite of backside.

Think of ventral (Latin venter = "belly") as being associated with the belly side (with belly referring to "swelling" or "inflating") -- or typically the side of the organism containing the digestive and respiratory organs.Dorsal (from Latin dorsum meaning "back") refers to the body region/"side" opposite that of ventral (and typically called the "back"). Although these terms differ between shapes/orientations of organisms, using such terms for more specific body parts (e.g., heads or feet) are not always as inconsistent. Although the direction indicated by "proximal" and "distal" is always respectively towards or away from the point of attachment, a given structure can be either proximal or distal in relation to another point of reference. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. [35] For example, the arm is peripheral to the body. It only takes a minute to sign up. For other uses, see, "Proximal" and "distal" redirect here. For example, anatomical positional terminology for. From prior reading, I thought that Dorsal is the same as Posterior and Ventral is the same as Anterior. How do you put grass into a personification? In invertebrates, the large variety of body shapes presents a difficult problem when attempting to apply standard directional terms. There is typically no basis for the definition of a third axis. Example: the ventral wall of the heart. Two specialized terms are useful in describing views of arachnid legs and pedipalps. • When a particular organ (A) is ventral to another (B), the organ-B lies dorsal to the organ-A. Standard anatomical and zoological terms of location have been developed, usually based on Latin and Greek words, to enable all biological and medical scientists, veterinarians, doctors and anatomists to precisely delineate and communicate information about animal bodies and their organs, even though the meaning of some of the terms often is context-sensitive. [1] In humans, this refers to the body in a standing position with arms at the side and palms facing forward, with thumbs out and to the sides. Isn't "2+2" correct when answering 'What is "2+2"'? Also, this Bio.SE post addresses anatomical terminology usage in plants and body organs. What is the lowest level character that can unfailingly beat the Lost Mine of Phandelver starting encounter?

How to deal with a younger coworker who is too reliant on online sources, Category theory and arithmetical identities. Cnidarians (jellyfish, sea anemones and corals) have an incomplete digestive system, meaning that one end of the organism has a mouth, and the opposite end has no opening from the gut (coelenteron). Turning right but can't see cars coming (UK). 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. [45] For this reason, the end of the organism with the mouth is referred to as the oral end (from Latin ōrālis 'of the mouth'),[61] and the opposite surface is the aboral end (from Latin ab- 'away from').[62]. The dorsal (from Latin dorsum, meaning 'back') surface of an organism refers to the back, or upper side, of an organism. 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. Where is the IAP also known as MAP sensor on a 1992 Dodge Stealth? [65], Aspects of spider anatomy; This aspect shows the mainly prolateral surface of the anterior femora, plus the typical horizontal eye pattern of the Sparassidae, Typical arrangement of eyes in the Lycosidae, with PME being the largest, In the Salticidae the AME are the largest, Standard terms for unambiguous description of relative placement of body parts, "Anterior" redirects here. More generally, a frontal plane always divides an organism into ventral/dorsal. Structures closer to the radius are radial, structures closer to the ulna are ulnar, and structures relating to both bones are referred to as radioulnar. Why are "south" and "southern" pronounced with different vowels?
