The flat bones are strong‚ flat plated‚ and provide protection for all the major organs‚ such as the brain‚ heart and the lungs. They can also provide attachment for muscles. Irregular bones are bones that don’t fit into any category‚ they help to support and protect joints‚ and an example of this would be the vertebrae. And finally‚ the sesamoid bones‚ they are usually short or irregular bones that are placed / imbedded

Anatomy and Physiology Introduction In this assignment i will carry full investigation and analysis on the Skeletal system‚using my class notes‚researching on the internet and reading books. The Skeletal system is the system of bones‚ associated cartilages and joints of human body. Together these structures form the human skeleton. Skeleton can be defined as the hard framework of human body around which the entire body is built. Almost all the hard parts of human body are components of human

musculoskeletal system includes bones‚ joints‚ skeletal muscles‚ tendons‚ and ligaments. The response this exercise does to the body is increased blood supply for muscles to work for longer and harder when exercising‚ muscle pliability will also develop as regular muscles are being used and developed making them stronger overall. Increased respiratory rate‚ increased fuel metabolism‚ increased oxygen consumption and also increased muscle temperature these are some of the features that will take

procedure to assess the health of muscles and the nerve cells that control them (motor neurons). Motor neurons transmit electrical signals that cause muscles to contract. An EMG translates these signals into graphs‚ sounds or numerical values that a specialist interprets. It is a technique for evaluating and recording the electrical activity produced by skeletal muscles. EMG results can reveal nerve dysfunction‚ muscle dysfunction or problems with nerve-to-muscle signal transmission. Careful registration

are in these systems are skeletal muscles‚ bones (joints‚ tendons‚ and ligaments). By dividing the two systems into different sections‚ it will make it easier for you‚ the reader‚ to understand and make sense of the information. The muscular system functions are to provide movement‚ protects organs‚ and production of heat. There are many muscles that do different functions. Before I go into all of the muscular functions‚ I will give an overview of all the muscle structure. Fascia‚ which is a fibrous

Ch 10 The unit of muscle structure that is composed of bundles of myofibrils‚ enclosed within a sarcolemma‚ and surrounded by a connective tissue covering called endomysium is a muscle fiber. The plasma membrane of a skeletal muscle fiber is called the Sarcolemma In a skeletal muscle fiber‚ Ca2+ is stored within the sarcoplasmic reticulum The bundle of dense regular connective tissue that attaches a skeletal muscle to bone is called a(n) tendon.
