The fanning of the primary bundle of light beams (411) is achieved by refraction on rotationally symmetric interfaces (471, 472), which are variably inclined in relation to the optical axis (417).

However, each row must have a unique primary key, which is a sort of name for that particular bundle of data.

Conclusion: the anterior bundle of UCL of the elbow is the primary restraint to valgus stress and should be the focus of repairing or reconstructive operation.
