1 They are inserted in the same order as that in which they arise: the most lateral of the clavicular fibers are inserted at the upper part of the anterior lamina; the uppermost sternal fibers pass down to the lower part of the lamina which extends as low as the tendon of the Deltoid and joins with it.
By extension of the American standards the half letter size meets the needs of many applications. It is also known as statement, stationery, Half A (from ANSI sizes) or simply half size. It is a piece of letter paper cut in half, 5.5 Ã 8.5 (140 Ã 216 mm).
There are a lot of mathematical fomulas behind the workings of A, B and C paper sizes but the underlying feature is that any successive paper size (eg. A1, A2, A3, A4) measurement is determined by halving the dimensions of the preceding one. For example the most commonly used paper size is A4 (297mm x 210mm) and the next paper size is A5 (210mm x 148.5mm) which is equal to half of the A4 dimensions. The main uses of A, B and C paper sizes is their application to a particular print project. For example C paper sizes are solely used for the manufacture of envelopes and are sized in a way that would allow an A4 piece of paper to fit nicely into a C4 envelope.
