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.

The Cambrian Explosion is a sudden appearance of all life as we know it. There are exceedingly few that come before this and those that follow the Cambrian show no differences than their ancestral cousins or predecessors that follow. It is like an explosion of life that appears almost instantaneously on earth. What is amazing about the Cambrian layer is what is not there before it and after it. In other words, you will find almost no predecessors or ancestors of the Cambrian creatures; that is, absolutely nothing above or below this layer.
