ЧТО ОЗНАЧАЕТ СЛОВО DEXTRAL
Синастральный и правый
Sinistral и dextral - научные термины, которые описывают хиральность или относительное направление по ряду дисциплин. Термины взяты из латинских слов для «левого» и «правого». Другие дисциплины имеют разные термины или просто используют левый и правый. Относительное направление и хиральность - это разные понятия. Относительное направление - с точки зрения наблюдателя. Полностью симметричный объект имеет левую и правую стороны, с точки зрения наблюдателя, если определены верхнее и нижнее и направление наблюдения. Хиральность, однако, независима от наблюдателя: независимо от того, как смотреть на правую винтовую резьбу, она по-прежнему отличается от левой винтовой резьбы. Следовательно, симметричный объект имеет сугубо логическое и правостороннее направления, произвольно определяемые положением наблюдателя, тогда как объект, имеющий хиральность, может иметь начальные и правосторонние направления, определяемые характеристиками объекта, независимо от положения наблюдателя.

B. Maternal Factor Determining Cleavage Handedness The typical spiral
cleavage pattern is dextral (clockwise at the third cleavage), although some
species, Physa, for example, have a sinistral (counterclockwise) spiral cleavage
pattern.
