animals: connective‚ muscle‚ nervous‚ and epithelial. We are going to go into muscle tissue. The cells of muscle tissues are called fibers. There are three types of muscle tissue and they are skeletal‚ cardiac‚ and smooth. All types can go though hypertrophy (enlargement or overgrowth of an organ or part of the body due to the increased size of the constituent cells). Muscle fibers contract due to the interaction of the contractile proteins‚ actin and myosin. Muscle contraction generates contractile

Endomysium- covers the individual muscle fibers Sarcomere- smallest contractile element of muscle fiber‚ extends from z-line to z-line Myofilament- responsible for contraction Striated- the color variations on the muscle fiber. Has to do with the amount of protein and the way it reflects light. Myosin- globular protein Bulb like heads come in contact with the active sites on actin Active sites are not exposed when in the resting position

The Skeletal System 2/17/13 Period: 2 Sierra Smith Emily Johnson Imani Rigguns The skeletal system is one of the most important systems in the human anatomy. Without this system our bodies wouldn’t have any source of motion or movement. From the skull all the way to the toes of our feet‚ everything is important. Out of the 206 bones‚ they all form our different shapes and make us all unique. They create our framework and enables us the move and perform our different

Professor: Pierre Louis‚ Vertulie 4/16/13 A&P SKELETAL PROJECT! This system has 206 bones and associated cartilage‚ tendons‚ and ligaments. Because bone is unbending‚ it gives the body a structure‚ maintains its shape‚ and protects essential organs. Bones provide a place for muscles and supporting structures to attach‚ and‚ with the movable joints. A joint is a place of union between two or more bones that may be movable or immovable. Bone also functions as a place for mineral storage

Skeletal System Skeletal system is the biological system providing support in living organisms. Skin‚ muscle and bones allow movement. Skin - pliable covering. Muscles do actual moving. Bones give anchor to move against. The skeleton functions not only as the support for the body but also in haematopoiesis‚ the manufacture of blood cells that takes place in bone marrow. This is why people who have cancer of the bone marrow almost always die. It is also necessary for protection of vital organs
