Muscular System . Muscles Attach To The Skeleton By Tendons.

Skeletal Muscle Structure.The cells of skeletal muscles are long fiber-like structures. They contain many nuclei and are subdivided into smaller structures called myofibrils. Myofibrils are composed of 2 kinds of myofilaments. The thin filaments are made of 2 strands of the protein actin and one strand of a regulatory protein coiled together. The thick filaments are staggered arrays of myosin molecules.

system is to provide movement for the body. The muscular system consist of three different

Firstly, an isometric contraction is when the length of the muscle does not change and the angle of the joint does not change. The muscle is active during this contraction but it is in a static position. An example of this is when you stop halfway when doing a squat or push-up or holding yourself in an abdominal plank position. This type of muscle work is quite easy to do, however it can result in fatigue very quickly. Furthermore, this type of muscle work can cause a sharp increase in the blood pressure in the body because blood flow is reduced. Another type of muscle contraction is the concentric muscle contraction; this occurs when a muscle shortens against a resistance, an example of this is a bicep curl. The brachialis and bicep shorten, bringing your forearm towards your upper arm. These types of contraction are also known as the positive phase of muscle

These muscle tissue cells specialised to contract and move parts of the body. It is also capable of responding to stimuli. There are three types of muscle in the body such as: skeletal, cardiac and smooth. Each muscle is created of muscle fibers that are capable of contracting and returning back to original state-relaxation. Contraction causes movement of the skeleton, soft tissue, blood or specific material. Skeletal muscle is attached to the bones of the skeleton. Some facial muscles are attached to the skin. They have direct control over them through nervous impulses from our brain sending messages to the muscle. Contractions can vary to produce fast, powerful movements. These muscles also have the ability to stretch and contract to return to original shape. Cardiac muscles are found in the chambers of the heart such as the atria and ventricles. It is under the control of the automatic nervous system; however, even without nervous input contractions can occur. It is completely different to all the other muscles. Smooth muscles are also known as involuntary due to our inability to control its movement. This muscle is usually found in the walls of hollow organs

10. two of the main types of muscle tissue correspond with muscles that are involuntary, they are cardiac muscle, which includes the heart. Smooth muscle, which is also involuntary, and includes the stomach, intestines, uterus, urethra, bladder, and blood vessels. The Skeletal muscles are voluntary, they’re attached to the bone and are used to affect skeletal movement.

The EMS increase also the strength ans muscular mass, and you can elevate the intensity of your training, means more and more fibres are recruited in the

1. The 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

Smooth muscles are found in the skin, internal organs, reproductive system, major blood vessels, and excretory system. Skeletal muscles are composed of long fibers surrounded by a membranous sheath, the sarcolemma. Since the Skeletal muscles are under control by whom ever they belong to are called voluntary muscles. This muscle is attached to two or more bones which are then attached to the skeleton by tendons. For example, head and neck muscles; contraction of these muscles produces facial expressions and head movements. They are also responsible for speech and swallowing. Skeletal muscles are the main muscles which move your body. Muscles nearly always work in coordinated groups; contraction of one muscle is accompanied by relaxation of another, while other muscles stabilize nearby joints. Then the last of the muscle types is the Cardiac Muscle or the involuntary muscles. Cardiac muscles are not under conscious control they do not react by a persons decision or movement. and are connected to the nervous system which are stimulated by autonomic impulses. Cardiac muscles are found in your internal organs like the heart or the intestine. For example; they include muscles that propel food through the intestine and those that control sweating and blood pressure.

Equines have been essential to the evolution of our society for over 4,000 years, providing speed and strength to aid in work, travel, and war. They are extreme athletes, capable of producing high speeds and stamina and are able to do so efficiently. This is due partly to the muscle physiology of the equine. In most mammals, 40-45% of body weight is made of muscle mass. In horses this percentage is increased to over 50%. Horses are not all the same, however. Different breeds have different skeletal muscle builds as well as muscle types. For example, the Thoroughbred, one of the most athletic breeds of horses, has a muscle mass percentage of almost 55%. (Gunn, 1979) Conditioning of our equine athletes is an important part of equine care, especially

When you begin running your body starts using ATP converting it into adenosine diphosphate (ADP) another molecule that gives you energy. Our cells then begin to break down GLYCOGEN (a type of glucose stored in our molecules) in order to produce more ATP. Our body only stores 2-3 seconds of ADP after the initial exercise cells recycle the ADP back into ATP. The process of converting ATP to ADP and back creates the release of lactic acid. After 10 minutes our body efficiently uses OXYGEN, BURNS FAT and GLUECOSE.

The functions of the muscular system. There are more than six hundred muscles located in the human body, all with assigned jobs. The nervous system panels the actions of the muscles and the circulatory system supplies the muscles with a opulent blood supply that delivers fuel for the muscles. Through its many muscles, the muscular system: • Allows human movement.

Skeletal muscles consist of numerous elongated cells called muscle fibres; these fibres are arranged in bundles called fasciculi. Each muscle is composed of hundreds of muscle fibres enclosed within a protective tissue envelope; most of these fibres extend the full length of the muscle. The fibres within each fasciculus are separated

The major training responses take place in the blood, heart, muscles and cardiovascular system. Within the first two- four months of training there is normally an increase of blood volume, red blood cell count, and haemoglobin concentrations. This will normally result in a more efficient circulatory system. An increase in the blood plasma in the first few weeks of training will contribute to the horse having better thermoregulation and a better sweating capacity. After the horse has undergone 3-6 months of training, an improvement in the network system as the number and density of capillaries provide a more efficient blood flow. With this greater increase in blood flow more oxygen can therefore be delivered to the working muscles in order for them to keep up with the greater demands put upon them.

Another effect of exercise to muscular system is the enlargement of the muscle. As regular as you do an exercise in the gym by lifting weights, your body will continue adding size to meet the imposed demand (Jordan T.S.).Having a long term exercise can generate muscle fibers growth known as hypertrophy. Having a resistance training will increase overall synthesis which is the main building block for muscle. When you lift an overload weights it will increase the number of contractile filaments with in the muscle cells. This will make the enlargement of muscle cells that makes the entire muscle larger(Weir J., 2010).

Muscle tissues are found attached to the bones, the walls of hollow internal organs, and the heart. Their main function involves movement. These tissues react to a stimulus called muscle fibers. When these muscle fibers contract, they pull at their attached ends and this is how we move different parts of our body. There are three main types of muscle tissue: skeletal, smooth, and cardiac. Skeletal muscle tissues are found in muscles attached to bones. Smooth muscle tissues are found on the walls of hollow internal organs. Cardiac muscle tissues are only in the heart.
