Chapter 8, Problem 19RAC
Summary Introduction
Introduction:
Joints are formed by the articulation of the surfaces of two or more bones. They also consist of cartilage, synovial membrane, ligaments, tendons, synovial fluids, bursa and meniscus. With aging, there are a number of changes that occur within the joints due to a decrease in strength of ligament and tendons and the modification in the protein structure of collagen fiber.

Whenever the position of a joint is stabilized at a certain attitude, the nervous system produces this by :-
a- increasing the α-motor neuron discharge to all muscles attached to the jointb- increasing the γ-motor neuron discharge to all muscles attached to the jointc- increasing γ-motor neuron discharge to postural musclesd- co-activation of α and γ-motor neurons innervating the involved muscles
Molly is a 10-year-old girl of short stature with hyperelastic skin which bruises easily, and hypermobile joints which are easily dislocated. Molly's mother said that Molly's diet includes fruits and vegetables high in Vitamin C, so she does not have a vitamin C deficiency. She also has no signs of anemia and has normal iron levels.
You decide to refer Molly to a surgeon who will correct the looseness of Molly's joints. The surgeon agrees to take skin samples during the surgery so that you can perform an analysis of her fibroblasts. These cells produce connective tissue in the skin. Because skin, ligaments, and tendons have collagen as their major structural protein, you suspect that Molly is unable to synthesize collagen properly and you wish to test this hypothesis.
That evening, you have dinner with your old college friend, who is now a veterinarian. You describe Molly's symptoms to her and she remarks that Molly's symptoms sound remarkably similar to a condition called…

Calcium is pumped into the sarcoplasmic reticulum
Active sites on actin are revealed
Release of calcium from terminal cisternae
Troponin changes its shape

- Which statement or statements describe why depletion of ATP after death leads to rigor mortis? Select all that apply. ATP is required to move tropomyosin back over the active sites of thin filaments. ATP is required for myosin thick filaments to detach from actin thin filaments. ATP is required to pump calcium back into the sarcoplasmic reticulum. ATP is required for the action potential to spread across the sarcolemma.arrow_forwardThe changes related to muscle mobility are the most obvious in older adult. There can be measurable differences in muscle strength, endurance, range of motion, coordination, elasticity, and flexibility of connective tissue. Regular exercise is necessary to prevent a decrease in muscle strength. Exercise helps to strengthen muscles and keeps joints, tendons, and ligaments more flexible, allowing for a more active lifestyle. Please research and describe some activities you could recommend to an elderly patient to stay active to help them maintain muscle massarrow_forwardRunning, or exercise/sports in general at the recreational level, is not associated with an increased risk of osteoarthritis of the lower limb joints. Why is this? Healthy cartilage is really good at repairing itself from damage in adulthood. Don't know for sure, but it's suspected that the strains involved trigger the cartilage to grow stronger, especially when young. O The peak loads these movements place on joints are small, similar to the peak loads in walking O The stress-life of cartilage is long enough that these activities cannot exhaust itarrow_forward
- All of the following are important functions carried out by the skeletal system Except O produces red and white blood cells stores the majority of water for the body stores and releases minerals and fat protects important internal organs supports the bodyarrow_forwardWhen a person dies, the body often experiences rigor mortis. In this condition, it is as if the muscles have become inflexible and it is very difficult to manipulate gather joints. Why does this occur?arrow_forwardAll of the following are important functions carried out by the skeletal system Except produces red and white blood cells stores the majority of water for the body stores and releases minerals and fat Oprotects important internal organsarrow_forward
- In the classification of joints, which of the following is true? in cartilaginous joints, a joint cavity is present symphyses are synarthrotic O synarthrotic joints are slightly movable sutures are diarthrotic synovial joints are diarthroticarrow_forwardWhat happens when the muscular action potential spreads through transverse (T) tubules of the sarcolemma? The action potential in T tubules triggers the release of acetylcholine from the axon terminals of the motor neuron. The action potential in T tubules triggers closing of sodium channels and opening of potassium channels, which enables myosin cross bridges to form. The action potential in T tubules opens voltage-sensitive calcium channels in the T tubules, allowing calcium to flow into the sarcoplasm. The action potential in T tubules causes a shape change in voltage-sensitive proteins that pull open calcium channels in the sarcoplasmic reticulum.arrow_forwardThe cartilage plays useful role in joint lubrication. False Truearrow_forward
- Which of the following bones is the site of insertion for trapezius, levator scapula and the rhomboids? Clavicle Humerus Scapula sternum The cyclic pattern of the engagement of the muscle and joints of the body during walking is known as the Ambulation cycle Gallop cycle Gait cycle Motor cycle If a client's neck is rotated to the right , which muscle is in a shortened position? Left Stercleidomastoid Right scalenes Left levator scapula Left splenius capitisarrow_forwardWhich of these sentences best describes an anatomical study? 1) how using certain muscles changes the shape of the bones they are attached to 2) how UV radiation is involved in vitamin D production 3) how vaccines activate immune cells 4) how electrolytes balance may affect muscle crampingarrow_forwardAt the clinical examination of the patient for 70 years old: a violation of motor functions was found, which is associated with age-related changes in the hyaline cartilage. What age-related changes have caused movement disorders in the joints? * Perichondrium thickening Increasing the number of cartilage cells Increase in the number of isogenic groups Increase hydrophilicity of the main substance O Deposition of calcium salts in the intercellular substancearrow_forward
