dÃ©jÃ  vu [(day-zhah vooh)] The strange sensation that something one is now experiencing has happened before: âI knew I had never been in the house before, but as I walked up the staircase, I got a weird sense of dÃ©jÃ  vu.â From French, meaning âalready seen.â.
Muscle is a soft tissue found in most animals. Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell.uscle tissues are derived from the mesodermal layer of embryonic germ cells in a process known as myogenesis. There are three types of muscle, skeletal or striated, cardiac, and smooth.
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.eat production: The contraction of muscle produce heat, which keeps the body warm during the winter cold months. The production of heat is also an indication of active metabolic activity in the muscle tissue.
