Skeletal muscle is attached to bones, cardiac muscle makes up the walls of the heart, and smooth muscle is found in the walls of internal organs and other internal structures. How does the heart resist fatigue? This entire process falls under the subject of motor control. Chapter 6 the muscular system answer key figures. 6 Disorders of the Muscular System: Review Questions and Answers. There are two principles that govern the relationship between motor neuron activity and muscle force: the rate code and the size principle.
Carpal tunnel syndrome is a biomechanical problem that occurs in the wrist when the median nerve becomes compressed between carpal bones, often due to repetitive use of the wrist and typically causing pain, numbness, and eventually muscle wasting in the thumb and first two fingers of the hand if untreated. Describe one of its functions. 10 Sensory Innervation of Muscle Spindles. Connective tissue in the interior cavity of a bone where blood cell formation (hematopoiesis) takes place. Muscular system worksheet answer key. Relate muscle fibre structure to the functional units of muscle fibre consists of a bundle of myofibrils, which are bundles of protein filaments. B. Intrafusal fibers.
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. Its firing rate does not depend on the rate of change of the muscle; rather, its firing rate depends only on the immediate length of the muscle. Additionally, ligaments composed of dense connective tissue surround these joints, tying skeletal elements together (a ligament is the dense connective tissue that connect bones to other bones). Chapter 6 muscular system answer key. Sample answer: Tendons and nervous system tissue. Physical exercise can also increase factors associated with good cardiovascular health, such as "good" cholesterol level and the mechanical efficiency of the heart. Making the same movement while removing a 2-lb weight from your pocket may result in the same trajectory of your hand, but will require different sets of forces on the muscles that make the movement. 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. These curvatures often appear in preteens as the result of poor posture, abnormal growth, or indeterminate causes.
Skeletal muscles also have connective tissue supporting and protecting the muscle tissue. Without red bone marrow, you would not be able to produce blood cells. Muscle spindles are collections of 6-8 specialized muscle fibers that are located within the muscle mass itself (Figure 1. Part 3: Cat Muscles and Dissection. Why does this orderly recruitment occur? Suppose your red bone marrow could not be formed. Thus, the white meat of a chicken, used to control the wings, is composed primarily of fast-twitch fibers, whereas the dark meat, used to maintain balance and posture, is composed primarily of slow-twitch fibers. Spinal curvatures can also be excessive dorsoventrally (kyphosis) causing a hunch back and thoracic compression. The arm would straighten out. 6 demonstrates how the size principle governs the amount of force generated by a muscle.
Three types of muscles are skeletal, smooth, and cardiac muscles. Note that the Ia afferent is not affected, as the muscle length has not changed. The motor system must generate movements that are adaptive and that accomplish the goals of the organism. A skeletal muscle consists of bundles of muscle fascicles, each of which in turn consists of bundles of muscle fibres. Sample answer: Two examples of flexibility exercises include stretching and yoga.
The brain has evolved exceedingly complex and sophisticated mechanisms to perform these tasks, and researchers have only scratched the surface in understanding the principles that underlie the brain's control of movement. Explain your answer. Skeletal muscle is attached to bones by tendons. Golgi tendon organs signal information about muscle force, but do not control that force directly.
Muscle fibres are bundled together in fascicles. List four characteristic signs of the disorder.
