Muscular system provide energy for exercises lasting up to ten seconds. Recovery is very quick, with full creatine stores regenerated within five minutes. Multiple diseases can affect the muscular system. Muscular system The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture and circulates blood throughout the body. The muscular systems in vertebrates are controlled through the nervous system although some muscles (such as the cardiac muscle) can be completely autonomous. Together with the skeletal system, it forms the musculoskeletal system, which is responsible for movement of the human body.
Cooperative Human Tissue Network Cooperative Human Tissue Network The Collaborative Human Tissue Network (the CHTN) was established in 1987 by the National Cancer Institute in response to an increase in the demand for high quality biospecimens for cancer research. The purpose of the CHTN is to stimulate, for the good of the public, cooperative efforts to collect and distribute human biospecimens and to thereby facilitate research utilizing those specimens. These activities are expected to encourage basic and developmental studies in many areas of cancer research, including molecular biology, immunology and genetics. The CHTN is not intended to be a human tissue bank, but instead
