The asymmetrical tonic neck reflex (ATNR) is a primitive reflex found in newborn humans that normally vanishes around 6 months of age. It is also known as the bow and arrow or "fencing reflex" because of the characteristic position of the infant's arms and head, which resembles that of a fencer. When the face is turned to one side, the arm and ...
A reflex bow is a bow that has curved or curled arms which turn away from the archer throughout their length. When unstrung, the entire length of the bow curves forward from the belly (away from the archer), resembling a "C"; this differentiates a reflex bow from a recurve bow in which only the outer parts of the limbs turn away from the archer.

In the subsequent standardization of Korean archery, the nature of the bow and the arrow was standardized, as was the range of the targets. Korean traditional archery now uses one specific type of composite bow, bamboo arrows, and a standard target at a standard distance of 120 bo (about 145 m or 160 yards). Korean Archery as a sport developed ...
The Manchu bow follows the same basic layout as other Asian composite reflex bows. The bows were formed using frames of either wood, or a mixture of wood and bamboo, to give shape to the bow. [ 1 ] Strips of horn were then glued, using a collagen-based, extremely durable glue made from fish bladders, to the compressing side of the working limbs.
When the bow is drawn, the sinew (stretched on the outside) and horn (compressed on the inside) store more energy than wood for the same length of bow. The strength can be made similar to that of all-wood "self" bows, with similar draw-length and therefore a similar amount of energy delivered to the arrow from a much shorter bow. However ...
