Cardiac muscle

and give the body support, and pump blood cells. The bones have skeletal muscles that help produce movement. With the joints they act like fulcrums while the bones and muscles work and act like a lever. Depending on how close or far away of the load to the joint make the bones and muscles create a mechanical advantage or disadvantage when lifting an object. The bone that is stationary is the skeletal system. The skeletal muscles are attached by bones by tendons which help move the body. The tendon is

Cellular adaptations of growth and differentiation In order to function properly, the cells and tissues have to maintain a steady state (homeostasis)- the cells must constantly adapt cellular adaptation- is the state between a normal unstressed cell and the overstressed injured cell -by definition - an adaptative process is reversible -within defined limits, all the cells are capable of adapting to a variety of stimuli which may upset normality NORMAL CELL GROWTH -Normal tissue growth

three organs the heart, blood vessels, and blood. They work together in order to provide oxygen throughout the whole body, the heart composed of cardiac muscle is the main organ in the human body without it we won’t be able to live it, its function is mostly to pump blood throughout the whole body. The blood vessels are composed mainly by smooth muscle throughout the whole body carrying blood such as the arteries and the veins, which takes carbon dioxide and other waste out of the body. There are

The Muscular System The muscular system moves the body. The body has more than 600 muscles and each of them has special fibers that contract. When a muscle contracts, it pulls the tissue that it is attached to. This pulling results in movement. Skeletal muscles are probably the most familiar type of muscle. They are the muscles that ache after strenuous work or exercise. Skeletal muscles make up about 40 percent of the body’s mass or weight. They stabilize joints, help maintain posture, and give

smooth muscle and skeletal muscle is in the way actin and myosin is used during contraction, and the characteristics of the muscle cell as well. Skeletal muscles have long strands of multinucleate cells and are made of sarcomeres that form the striations within the cells. While smooth muscle, cells are not striated because they do not have sarcomeres and have a single nucleus. In addition, skeletal muscles are the only muscle cells out of the three that is voluntary. The third type of muscle cell is

action potential and the mechanical muscle contraction. Physiologically, it is a mechanism whereby an electrical signal detected by the dihydropyridine receptor is converted into an increase in calcium via activation of ryanodine receptors (RyRs). Per the article, mutations in RYR1, the gene encoding, are the underlying cause of various congenital myopathies including central core disease, multiminicore disease (MmD), which is a disorder that primarily affects muscles used for movement, as well as some

individual the larger the heart, lungs and muscle mass are, which contributes to them having a higher VO2max. Growth and maturation (Malina, 2014) Growth and maturation are terms that are often used in a similar context but each, however, specify a different biological process. Growth refers to the increase in body size both from an external perspective and an internal perspective: As a child grows, height and body mass increase due to changes in skeletal and muscle composition as well as increases in

P2: Outline the four main tissue types such as Epithelial, connective, muscle, nervous. Tissues are groups of cells, which are placed together to achieve a common function. There are four main types of tissue: Epithelial, connective, muscle and nervous. Most of these tissues are found in our bodies, however the epithelial tissue is covered all over the surfaces of the body. Epithelial tissue This tissue covers the whole surface of the body and is specialised to form the covering or lining

organs of the body. Tissues are a collection of similar cells that group together to carry out a specific function within the body. There are four different types of tissue found in the human body which include; epithelial tissue; connective tissue; muscle tissue and nerve tissue. The first type of tissue found in the human body is epithelial tissue. These types of tissue are found covering the whole surface of the body, lining of cavities, hollow organs and tubes. The cells a very closely packed and

for rotation around an axis. There is a pivot joint near the top of your spine that allows your head to move from side to side. Hinge joints. This type of joint can open and close like a door. Your elbow is a hinge joint. Your biceps and triceps muscles are basically two people standing on opposite sides of a wall (the humerus, or upper-arm bone), each with one hand reaching over to its respective side of a door (the bones of the lower arm). The biceps "shuts" the door, by contracting and lessening
