The Golgi organ (also called Golgi tendon organ, GTO, tendon organ, neurotendinous organ or neurotendinous spindle) senses changes in muscle tension.he tendon organ is a stretch receptor that signals the force developed by the muscle. The sensory endings of the Ib afferent are entwined amongst the musculotendinous strands of 10 to 20 motor units.
1 A sequence is a set of numbers, called terms, arranged in some particular order. 2  An arithmetic sequence is a sequence with the difference between two consecutive terms constant. 3  The difference is called the common difference. 4  A geometric sequence is a sequence with the ratio between two consecutive terms constant.
For example, the sequence 2, 6, 18, 54, ... is a geometric progression with common ratio 3. Similarly 10, 5, 2.5, 1.25, ... is a geometric sequence with common ratio 1/2. Examples of a geometric sequence are powers r of a fixed number r, such as 2 and 3. The general form of a geometric sequence is. where r â  0 is the common ratio and a is a scale factor, equal to the sequence's start value.
