The task of the motor system is to determine the necessary forces and coordination at each joint in order to produce the final, smooth motion of the arm. Initially, both Group Ia and Group II fibers fire at a certain rate, encoding the current length of the muscle. 2 Some Necessary Components of Proper Motor Control. For one, the bone tissue acts as a reservoir for a number of minerals important to the functioning of the body, especially calcium, and phosphorus. When the arm begins to rise, however, the Ia afferents fire, just as with the balloon. Muscular system worksheet pdf answer key. One of the key questions of research on motor control is to understand the functional roles played by each area. What is the muscular system? Neuromuscular disorders are systemic disorders that occur because of problems with the nervous control of muscle contractions or with the muscle cells themselves. Motor neurons are clustered in columnar, spinal nuclei called motor neuron pools (or motor nuclei).
Sample answer: Three reasons that muscle atrophy may occur include lack of physical activity, such as might occur with immobility due to a broken bone or surgery; starvation; and certain diseases, such as AIDS or cancer. Parkinson's disease is a degenerative disorder of the central nervous system that mainly affects the muscular system and movement. Chapter 6 the muscular system answer key.com. Muscle atrophy is a decrease in the size of muscle. These circuits execute the low-level commands that generate the proper forces on individual muscles and muscle groups to enable adaptive movements. Sample answer: Two examples of flexibility exercises include stretching and yoga.
Muscle tissue is a soft tissue that makes up most of the tissues in the muscles of the human muscular system. What are current recommendations for physical exercise for adults? Bone (osseous) tissue. Chapter 6 the muscular system answers key. The biceps and triceps muscles are shown above. Each muscle contains many muscle spindles; muscles that are necessary for fine movements contain more spindles than muscles that are used for posture or coarse movements. These fibers generate more force than slow-twitch fibers, but they are not able to maintain the force as long as the slow-twitch fibers. Be prepared to spend a fair amount of time on this unit. Raising one's hand from a resting position on a desk, compared to a resting position on top of the head, results in the same final position of the arm, but these two movements require different patterns of muscle activation. Motor neurons use a rate code to signal the amount of force to be exerted by a muscle.
The arm bends at the elbow and the forearm will move up. An increase in the rate of action potentials fired by the motor neuron causes an increase in the amount of force that the motor unit generates. Many skeletal muscles work in opposing pairs to move bones back and forth at joints. As the amount of current increases, the membrane potential of the larger motor neuron also increases, until it also reaches firing threshold. Dynamic nuclear chain fibers.
Cat Muscles - Photos of Muscles You Need to Know. Without red blood cells, your tissues would not be able to produce ATP using oxygen. This entire process falls under the subject of motor control. Thus, when the CNS instructs a muscle to contract, it not only sends the appropriate signals to the alpha motor neurons, it also instructs gamma motor neurons to contract the intrafusal fibers appropriately; this coordinated process is referred to as alpha-gamma coactivation. Myasthenia gravis is a genetic neuromuscular disorder most often caused by immune system antibodies blocking acetylcholine receptors on muscle cells and the actual loss of acetylcholine receptors.
Treatment can range from exercise to surgery. Bones also serve as a site for fat storage and blood cell production. Students also viewed. Without the skeletal system, you would be a limp mass of organs, muscle, and skin.
Sample answer: The connective tissue called epimysium surrounds skeletal muscles and anchors the muscles to tendons. Consider a large uranium plate of thickness 5 cm and thermal conductivity in which heat is generated uniformly at a constant rate of One side of the plate is insulated while the other side is subjected to convection to an environment at with a heat transfer coefficient of Considering six equally spaced nodes with a nodal spacing of 1 cm, (a) obtain the finite difference formulation of this problem and (b) determine the nodal temperatures under steady conditions by solving those equations. A skeletal muscle consists of bundles of muscle fascicles, each of which in turn consists of bundles of muscle fibres. The combination of an individual motor neuron and all of the muscle fibers that it innervates is called a motor unit. 4 Functional Segregation and Hierarchical Organization. Usually, however, our conscious actions require not only sensory input but a host of other cognitive processes that allow us to choose the most appropriate motor output for the given circumstances.
