How The Muscular System Enables Movement For The Body

How the muscular system enables movement for the body The muscular system enables the body to carry out all kinds of movements such as extension, rotation, abduction, adduction and flexion. For example the bicep helps to flex the arm and triceps help to extend the arm (working antagonistically). Muscles are attached to bones by tendons. The muscles contract to allow movement, while the skeleton gives the muscles support. Without muscles we would be able to move. Antagonistic pairs: Antagonistic pairs of muscles allow movement of parts of the body due to one muscle relaxing and the other muscle contracting. For example as the arm flexes the bicep contracts and the triceps relaxes which makes the bicep and tricep an antagonistic pair. Skeletal muscles always work in groups; they never work on their own. Agonist and antagonist: An agonist is a muscle which contracts while the other relaxes in an antagonistic pair. For example, when the arm flexes at the elbow joint the bicep is the agonist because hat muscle is contracting. An antagonist muscle is the muscle which relaxes as the other muscle contracts. For example, when the arm flexes at the elbow joint the tricep relaxes. Fixator – Muscles stabilise parts of the body to give the prime muscles a firmer base to work on. Synergist –this type of muscle works with another muscle to create a movement also like antagonistic pair muscles except as one muscle contracts another muscle does not necessarily relax to help flexShow MoreRelatedMuscular System . Muscles Attach To The Skeleton By Tendons.1359 Words   |  6 PagesMuscular System Muscles attach to the skeleton by tendons. Muscle tissue is responsible for the mechanical process of movement. The 650 muscles are given Latin names according to location, relative size, shape and their action. Muscles are signaled to contract via nerve impulses. The muscular system most important function is to create movement, it also protects the organs. The cardiac muscle is required to pump blood around the body and the smooth muscle ensures blood flow and aids digestion Read MoreThe Importance or Exercising Regularly832 Words   |  3 Pagesexertion while getting energy from the aerobic system used to supply the body with energy.

All organ systems within the body depend on one another for survival in some way or form at all times. Cherif et al., (2010) state, the body depends on the precise action of each organ to maintain physical, mental, and emotional health of a human being. Also, homeostasis, the regulatory of body temperature plays a survival role in maintaining body functions.

Version 42-0014-00-01 Purpose: What is the purpose of this exercise? In this exercise I will exam how joints function and thereby discover how they allow for movement in the body. Joints are where two bones come together. The joints hold the bones together and allow for movement of the skeleton. All of the bones, except the hyoid bone in the neck, form a joint. JointsRead MoreSuitable Population: The DynamicArm is the world’s first elbow joint prosthetic that is controlled1400 Words   |  6 PagesSuitable Population: The DynamicArm is the world’s first elbow joint prosthetic that is controlled by an electric motor. The Vario-Gear transmission allows the prosthetic to react immediately to different movements as well as continuously adapt to changing environments.1 Because of the capabilities of this prosthetic, it is very beneficial for those individuals who are physically active. However, the DynamicArm is suitable for almost all individuals with upper arm or shoulder amputations.

As blood flows through the body, waste products are deposited into the bloodstream that needs to be removed. The system that does this is the ‘Urinary system’ also known as the ‘Renal system’. It is made up of two kidneys, two ureters, a urinary bladder and a urethra that produce, store and then excrete urine out of the body.
