Raphael Brandon explains how rehab specialists can exploit our emerging knowledge of tendon properties. The properties and behaviour of the muscle-tendon complex (MTC) is a relatively new focus for sports science research, but it is attracting a lot of interest.rucially, the muscles and tendons interact, with the elastic properties of the tendons contributing both to the type and quality of movement. In almost all movements, when the muscle contracts, the tendon will lengthen before it shortens, independent of any change in muscle length.
Cambrian Explosion. A relatively brief time in geologic history (30-50 MY) when large, hard-bodied forms of animals with most of the major body plans known today appeared in the fossil record. This burst of evolutionary change occurred about 535-525 million years ago. No new major phyla since. relatively brief time in geologic history (30-50 MY) when large, hard-bodied forms of animals with most of the major body plans known today appeared in the fossil record. This burst of evolutionary change occurred about 535-525 million years ago.
While the early Cambrian showed such diversification that it has been named the Cambrian Explosion, this changed later in the period, when it was exposed to a sharp drop in biodiversity. About 515 million years ago, the number of species going extinct exceeded the amount of new species appearing.
