Her urine is dark colored. She wonders whether she may have damaged her muscles during the race. She visits the ER, and the doctor orders several blood tests.

Contraction produces a greater force than a concentric contraction. Contraction is used as an acceleration activity. Muscle attachments move farther apart. Movement occurs with gravity.arrow_forward
- Each of the pairs of phrases below describe steps during skeletal muscie contraction. The 2nd phrase should take place after the 1st phrase. Which of the pairs of phrases is out of order? muscle cell action potential leads to neurotransmitter release motor neuron action potential leads to muscle cell action potential sarcolemma depolarization leads to an increase in cytosolic calcium rise in cytosolic calcium leads to cross bridge cyclearrow_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_forwardThe change related to muscle mobility are the most obvious in older adult.

Take some time and write notes about each of the conditions. You may make the notes taken from text books or other resources, or you may make the notes as a result of people you have cared for.
