The Ib fibers do not change appreciably, because the balloon does not add much load to the muscle.

Intrafusal fibers This answer is INCORRECT. 6 Disorders of the Muscular System: Review Questions and Answers.

Identify three types of muscle tissue and where each type is found. Explain how crossbridge cycling and sliding filament theory are related to each other. Describe one way in which the muscular system is involved in regulating body temperature. Muscle force is controlled in part by... Chapter 6 the muscular system answer key figures. A. Alpha-gamma coactivation.
Suppose your red bone marrow could not be formed. What are musculoskeletal disorders? With stronger inputs, more motor neurons will be recruited, resulting in more force applied to the muscle (Play 2 and Play 3). Why is the heart the muscle that performs the greatest amount of physical work in the course of a lifetime? What are two tissues — other than muscle tissue — that can experience problems that result in muscular system disorders? Contractions of smooth muscles are not under conscious control. 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. On Earth, muscle cells are continually challenged by gravity, and moving and lifting objects against gravity is a form of physical activity that helps maintain the size of muscle fibres. 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. Muscular system worksheet answer key. Thus, all movements ultimately depend on the activity of lower motor neurons.
When force is applied to a muscle, the Golgi tendon organ is stretched, causing the collagen fibers to squeeze and distort the membranes of the primary afferent sensory endings. What is the difference between primary and secondary Parkinson's disease? This elaborate processing would be of limited value, however, unless we had a way to act upon the environment that we are sensing, whether that action consist of running away from a predator; seeking shelter against the rain; searching for food when one is hungry; moving one's lips and vocal cords in order to communicate with others; or performing the countless other varieties of actions that make up our daily lives. Muscular system worksheet pdf answer key. 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. Spinal curvatures can also be excessive dorsoventrally (kyphosis) causing a hunch back and thoracic compression. This is because the neurotransmitter acetylcholine is necessary to trigger muscle contractions at the neuromuscular junction by binding to its receptors on the muscle fibres. Name a muscular system disorder involving tendons. They are themselves components of complex circuits that perform sophisticated information processing.
Muscle Lab Guide: Muscles you need to know. The calcium in osseous tissue provides mineral support to bones. The motor system must constantly produce postural adjustments in order to compensate for changes in the body's center of mass as we move our limbs, head, and torso. For example, the act of moving your hand from inside your pocket to a position in front of you requires the coordinated activity of the shoulder, elbow, and wrist. Part 1: Muscle Basics. If a resting muscle is stretched, the muscle spindle becomes stretched in parallel, sending signals through the primary and secondary afferents. The function of mitochondria in muscle cells is to provide energy for the muscles in the form of ATP, through aerobic respiration. Muscle spindles are collections of 6-8 specialized muscle fibers that are located within the muscle mass itself (Figure 1.
Note that the Ia afferent is not affected, as the muscle length has not changed. They signal information about the static length of the muscle. The famous physiologist Sir Charles Sherrington referred to these motor neurons as the "final common pathway" in motor processing. Bones also serve as a site for fat storage and blood cell production. Sample answer: Two examples of flexibility exercises include stretching and yoga. Neuromuscular disorders are not due to biomechanical stresses (they often have a genetic cause); they usually affect most or all of the muscles in the body; and they are often progressive and incurable. Initially, both Group Ia and Group II fibers fire at a certain rate, encoding the current length of the muscle. A typical muscle spindle is composed of 1 dynamic nuclear bag fiber, 1 static nuclear bag fiber, and ~5 nuclear chain fibers. At the resting position, the Ia afferents of spindles in the triceps muscle fire at a steady rate to encode the present length of the muscle, and the Ib afferents of the Golgi tendon organs of the biceps muscle fire at a low rate. The organ is innervated by primary afferents called Group Ib fibers, which have specialized endings that weave in between the collagen fibers. Hard, dense connective tissue that forms the structural elements of the skeleton. A motor neuron controls the amount of force that is exerted by muscle fibers. Why does this orderly recruitment occur?
Finally, fast-twitch, fatigable fibers are recruited when the largest motor neurons are activated.
