Most radially symmetric animals are symmetrical about an axis extending from the center of the oral surface, which contains the mouth, to the center of the opposite (aboral) end. Animals in the phyla Cnidaria and Echinodermata generally show radial symmetry, [ 7 ] although many sea anemones and some corals within the Cnidaria have bilateral ...
Asymmetry is the absence of, or a violation of, symmetry (the property of an object being invariant to a transformation, such as reflection). [1] Symmetry is an important property of both physical and abstract systems and it may be displayed in precise terms or in more aesthetic terms. [2]
2. Arranged on opposite sides, e.g. leaves on a stem; Compare distichous and opposite. 3. Bilaterally symmetrical, as in a leaf with a symmetrical outline. biloculate Having two loculi, e.g. in anther s or ovaries. binomial Making use of names consisting of two words to form the scientific name (or combination) in a Latin form.
Sponges are asymmetrical. [1] Corals build colonies that are not symmetrical, but the individual polyps exhibit radial symmetry. [26] Alpheidae feature asymmetrical claws that lack pincers, the larger of which can grow on either side of the body, and if lost can develop on the opposite arm instead. [27]
Opposite to outermost (the adventitia, serosa, or the cavity's wall). [54] Parietal (from Latin paries 'wall'): pertaining to the outer wall of a body cavity. [55] For example, the parietal peritoneum is the lining on the inside of the abdominal cavity. Parietal can also refer specifically to the parietal bone of the skull or associated structures.
If the axial surface is vertical and the angles on each side of the fold are equivalent, then the anticline is symmetrical. If the axial plane is tilted or offset, then the anticline is asymmetrical. An anticline that is cylindrical has a well-defined axial surface, whereas non-cylindrical anticlines are too complex to have a single axial plane.

A crossword (or crossword puzzle) is a word game consisting of a grid of black and white squares, into which solvers enter words or phrases ("entries") crossing each other horizontally ("across") and vertically ("down") according to a set of clues. Each white square is typically filled with one letter, while the black squares are used to ...
