What is the muscular system? Calcium ions, for example, are essential for muscle contractions and are involved in the transmission of nerve impulses. Like the nuclear chain fiber, these fibers signal information about the static length of a muscle. These minerals, incorporated into bone tissue, can be released back into the bloodstream to maintain levels needed to support physiological processes. What may explain the positive benefits of physical exercise on cognition? Chapter 6 the muscular system answer key. Two terms are used to describe the anatomical relationship between motor neurons and muscles: the motor neuron pool and the motor unit. Because they innervate all 3 types of intrafusal fibers, Group Ia afferents provide information about both length and velocity. How does the heart resist fatigue? What mechanism may underlie many of the general health benefits of physical exercise? Printout of ALL Muscles we labeled and colored in class.
Explain why astronauts can easily lose muscle mass in space. In recent years, orthopedists have even performed prenatal surgery to correct spina bifida, a congenital defect in which the neural canal in the spine of the fetus fails to close completely during embryologic development. The muscular system answer key. The mechanism that may underlie many of the general health benefits of physical exercise is the release of hormones called myokines from contracting muscles. The heart is the muscle that performs the greatest amount of physical work in the course of a lifetime because it beats continuously throughout life without rest. A motor neuron controls the amount of force that is exerted by muscle fibers. Red bone marrow is where the production of blood cells (named hematopoiesis, hemato- = "blood", -poiesis = "to make") takes place.
A strained muscle is caused by the tearing of muscle fibres. Flexibility exercise is any physical activity that stretches and lengthens muscles. Musculoskeletal disorders are injuries that occur in muscles or associated tissues such as tendons because of biomechanical stresses. Padding of a strained muscle protects it from further impact. Both muscle fibres and myocytes are muscle cells. Muscular system worksheet pdf answer key. Larger motor neurons have more membrane surface and correspondingly more ion channels; therefore, they have a smaller input resistance. Why does this orderly recruitment occur? Cat Muscles - Photos of Muscles You Need to Know. What controls the contraction of smooth muscle? Thus, all movements ultimately depend on the activity of lower motor neurons. This entire process falls under the subject of motor control.
Because motor units are recruited in an orderly fashion, weak inputs onto motor neurons will cause only a few motor units to be active, resulting in a small force exerted by the muscle (Play 1). Initially, both Group Ia and Group II fibers fire at a certain rate, encoding the current length of the muscle. However, if the rate of firing of the motor neuron increases, such that a second action potential occurs before the muscle has relaxed back to baseline, then the second action potential produces a greater amount of force than the first (i. e., the strength of the muscle contraction summates) (Play 2). Attribute specific functions of the skeletal system to specific components or structures. Red blood cells, white blood cells, and platelets are all produced in the red bone marrow. Moreover, different types of muscle fibers are innervated by small and larger motor neurons.
If the acetylcholine receptors on muscle fibres were blocked by a drug, what do you think this would do to muscle contraction? If a muscle is required only for coarse movements (e. g., a thigh muscle), its motor units will tend to have a high innervation ratio (i. e., each motor neuron innervating 1000 or more muscle fibers), as there is no necessity for individual muscle fibers to undergo highly coordinated, differential contractions to produce a fine movement. Compare the response of the Group Ia afferent to the Group II afferent. List four characteristic signs of the disorder. Note that the Ia afferent is not affected, as the muscle length has not changed.
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. The filaments would not slide past each other and therefore muscle contraction would not occur. A skeletal muscle contraction is an increase in the tension or a decrease in the length of a skeletal muscle. During the stretch, the two types differ in their responses. Which type of muscle fibre has more mitochondria — slow-twitch or fast-twitch? In some cases the relationship between the sensory input and the motor output are simple and direct; for example, touching a hot stove elicits an immediate withdrawal of the hand (Figure 1. Bones also serve as a site for fat storage and blood cell production. 5 Physical Exercise: Review Questions and Answers. Contractions of smooth muscles are not under conscious control.
Myokines are endocrine hormones that promote tissue repair and growth and have anti-inflammatory effects. GetBodySmart - tutorials on major muscle groups. The motor system has a set of sensory inputs (called proprioceptors) that inform it of the length of muscles and the forces being applied to them; it uses this information to calculate joint position and other variables necessary to make the appropriate movement. They signal information about the static length of the muscle. Group Ib afferents are associated with Golgi tendon organs. Three types of muscles are skeletal, smooth, and cardiac muscles. Each individual muscle fiber in a muscle is innervated by one, and only one, motor neuron (make sure you understand the difference between a muscle and a muscle fiber).
This concept is illustrated in Figure 1. The sliding filament theory is the most widely accepted explanation for how a muscle contraction occurs. All of the motor neurons in a motor neuron pool innervate a single muscle (Figure 1. When the motor neuron fires a single action potential (Play 1), the muscle twitches slightly, and then relaxes back to its resting state. Muscle atrophy is a decrease in the size of muscle. Carpal tunnel syndrome may be treated by wearing a wrist splint, receiving corticosteroid injections, or undergoing surgery to cut the carpal ligament and reduce pressure on the median nerve. Four characteristic signs of the disorder are muscle tremor, rigidity, slowness of movement, and postural instability. Outline the cause and progression of myasthenia gravis. 4 Functional Segregation and Hierarchical Organization. Other sets by this creator. A dense connective tissue that connect one whole bone to another whole bone.
What will be the angular velocity at which the maximum power be delivered? Muscular dystrophy is a genetic disorder caused by defective proteins in muscle cells. Why can carpal tunnel syndrome cause muscle weakness in the hands? Some functions of the skeletal system are more readily observable than others. In order to make a desired movement (e. g., raising your hand to ask a question), it is essential for the motor system to know the starting position of the hand. They are themselves components of complex circuits that perform sophisticated information processing. Skeletal muscle is attached to bones by tendons. 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. Additional Practice and Other Resources. The slow-twitch fibers generate less force than the fast-twitch fibers, but they are able to maintain these levels of force for long periods. Imagine if walking across the room required thinking about planting the foot at each step, paying attention to the movement of each muscle in the leg and making sure that the appropriate forces and contraction speeds are taking place. 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.
Relate physical exercise to cardiovascular disease risk. These goals are evaluated and set by high-order areas of the brain. A muscle strain occurs when muscle fibres tear as a result of overstretching. Without red blood cells, your tissues would not be able to produce ATP using oxygen. Gamma motor neurons innervate intrafusal fibers, which contract only slightly. Activation of gamma motor neurons prevents this temporary insensitivity by causing a weak contraction of the intrafusal fibers, in parallel with the contraction of the muscle. Sample answer: Musculoskeletal disorders are due to biomechanical stresses; typically only affect just one or a few muscles; and are often fully treatable. These fibers produce large amounts of force, but they fatigue very quickly. If the muscle were to be stretched again, the muscle spindle would not be able to signal this stretch. If the motor neuron fires after the muscle has returned to baseline, then the magnitude of the next muscle twitch will be the same as the first twitch.
The red bone marrow is responsible for forming red and white blood cells as well as platelets. By comparing desired activity with actual activity, sensory feedback allows for corrections in movements as they take place, and it also allows modifications to motor programs so that future movements are performed more accurately. Most muscles contain both fast- and slow-twitch fibers, but in different proportions. Why is skeletal muscle tissue striated? Students also viewed. Some orthopedic problems can be treated with medications, exercises, braces, and other devices, but others may be best treated with surgery (Figure 6.
D. Golgi tendon organs.
