MUSCLES AND MUSCLE TISSUE. Muscle is composed of fibers, nerves and connective tissues and account for over 40% of the body weight. The fibers contract to produce tension on the associated tissues or tendons.Muscle tissue is enclosed in facia, which in turn is attached to other structures including ligament.There are three types of muscle tissues: skeletal, cardiac and smooth muscles. Muscle tissue provides a) posture and body support b) locomotion and c) heat production.. FUNCTION AND TYPES OF MUSCLE. Locomotion: One of the most obvious functions of muscle tissue is locomotion. When muscles contract, the fibers pull or relax bones to which they are attached, thus causing locomotion.

In addition it could also be a Geo-scientist as follows: Geoscientists study the composition, structure, and other physical aspects of the Earth. They study the Earth's geologic past and present by using sophisticated instruments to analyze the composition of earth, rock, and water.
Astrobiologists, also known as exobiologists, life scientists, and space scientists, study the origin of all life formsâfrom a simple one-celled organism, to plants, to human beings. They study and research the evolution, distribution, and future of these life forms, on Earth as well as on other planets in our solar system and beyond. Many astrobiologists are employed by the National Aeronautics and Space Administration (NASA) and other government-funded agencies. They are also employed at private research institutions and colleges and universities.
