Concept explainers

Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are the important contractile proteins involved in muscle action. Muscle contraction, in addition to movement, serves several other important functions in the body, including posture, heat generation, and joint stability. Muscle contraction maintains posture, which includes standing and sitting.

A physically active 13-year-old boy is complaining of pain at the posterior heel below the attachment of the achilles tendon. What are the possible reasons for his pain and what is the most likely cause? Explain your reasoning. What is the anatomical significance of the location of his pain? Does his age make a difference in how he should be managed? Are there any risks in ignoring the problem? Are there other locations in the body in which similar conditions occur?
Adequate level of muscle tone is essential for the accurate performance of voluntary movements, because :-a- it adjusts the α -motor neuron discharge initiating voluntary movementsb- it adjusts posture of proximal joints of the acting limbsc- it adjusts the upright posture of the whole body during voluntary movementsd- it adjusts sensitivity of the spindles of the involved muscles

Polymyositis is a muscle disease characterized by the simultaneous inflammation and weakening of voluntary muscles in many parts of the body. _______________ _______________ _______________ _______________
Which of the following statements are true? Multiple Choice Muscles work in antagonistic pairs because if one muscle shortens during contraction, the opposing muscle across the joint must relax. Muscles work in antagonistic pairs because tendons lengthen during contraction. Muscles work in antagonistic pairs because muscles lengthen during contraction. Muscles work in antagonistic pairs because if one muscle pushes during contraction, the opposing muscle across the joint must pull.
Neuromuscular diseases primarily affect skeletal muscles. Which of the following could be the result of a neuromuscular disease? Difficulty controlling air flow through bronchioles because the muscles that wrap around them are partly paralyzed. Difficulty exhaling because the external intercostals are partly paralyzed Difficulty inhaling because the diaphragm is partly paralyzed
Researchers are working to understand a rare disease that affects the ability of the muscles to contract. They have identified that the disease is caused by abnormal gene expression leading to a relatively large intracellular space between the T-tubules and the terminal cisternae in the triad, which causes an interruption in the connection between the dihydropyridine (DHP) receptor and the ryanodine calcium channel. Based on this description of the morphology underlying the disease, which of the following problems would you expect in excitation-contraction coupling? An action potential would not be able to be transmitted down the T-tubule. Re-uptake of calcium would be blocked, leading to an increase in intracellular calcium. O The actin binding sites may continue to be blocked by tropomyosin even following an action potential along the sarcolemma. O All of the above. Only B and C.
Repetitive extension of the hand at the wrist and abduction of the hand can lead to lateral epicondylitis.

Jason is a 21-year-old university student presenting with pain in the back of his right thigh. The pain started yesterday during soccer game. Jason went to kick the ball and felt an immediate 'pull' in the back of his right upper thigh. He had to limp off the field and reported mild pain in his right hamstring muscles with most active movements involving knee flexion and extension. Jason can still walk around without too much discomfort. a) What is the most likely cause of Jason's pain?
