Hannah Loback Muscle Essay The muscular system is a network of tissues that controls movement of the human body. Attached to the skeletal system are a multitude of muscles consisting of tissues‚ blood vessels‚ tendons‚ and nerves. Muscles are a bundle of fibrous tissue in the body that have the ability to contract‚ thus producing movement and maintenance of body parts. Without this system the ability to function and maintain a healthy lifestyle would be impossible. Correct posture‚ locomotion‚ and

due to Muscular Dystrophy‚ also called (MD). Muscular dystrophy is a genetic mishap that weakens the body’s muscles. There is no single disease called muscular dystrophy. Muscular Dystrophy refers to a group of more than 30 inherited diseases. These diseases affect the voluntary or skeletal muscles‚ which control the movements of legs‚ arms‚ and other limbs. Some organs‚ such as the heart and the gut‚ are also affected by the disease. Muscular Dystrophy can prevent the movement of the muscles any human

Mr.Jorez Human Muscular System Visceral muscle is found inside of organs like the stomach‚ intestines‚ and blood vessels. The weakest of all muscle tissues‚ visceral muscle makes organs contract to move substances through the organ. Because visceral muscle is controlled by the unconscious part of the brain‚ it is known as involuntary muscle—it cannot be directly controlled by the conscious mind. The term “smooth muscle” is often used to describe visceral muscle because it has a very smooth

able to exert great bodily or muscular power. Another component of muscular fitness that is crucial is muscular endurance‚ which is the ability to perform a specific muscular action for a prolonged period of time. For example‚ performing 50 squats with a weight of 50 kilograms on the shoulders requires both attributes‚ 150 squats without weight requires more muscular endurance while the ability to perform a single squat with a weight of 200 kilograms depends on muscular strength. Different tests are

The Muscular System: Contraction of Motor Units 1. Define a motor neuron:_____A single nerve cell that branches from the brain or the spinal cord to a muscle or a gland. 2. Define a motor unit: ___A motor neuron and all of the muscle fibers it stimulates. 3. The synapse between a motor neuron and the muscle it innervates is called a ____neuromuscular junction_______. 4. The stimulation of additional motor units will increase the strength of the contraction. This process is called
