The Terminal Cisternae are: A. The basic contractile unit in skeletal muscle OB. Equivalent to the cell membrane which covers the entire fiber. OC. A highly organized array of contractile units. OD. A specialized structure of the Sarcoplasmic reticulum which stores calcium. OE. None of the above.
Which of the following statements regarding skeletal muscle is NOT true? Skeletal muscle is responsible for overall body motility. Skeletal muscle can contract rapidly and can maintain the contraction for long periods of activity .Skeletal muscle can exert tremendous power. Skeletal muscle is called voluntary muscle because it is the only type subject to conscious control.
Label the connective tissues of a muscle
Which of the following are aspects of the structure of skeletal muscle? Select all that apply. The muscle fibers are parallel to one another and have a striated appearance. They have more mitochondria than other types of muscle cells. Each fiber contains many units of contraction and protein filaments. Cells are branched or unbranched with single nuclei. It consists of cylindrical cells called muscle fibers that have multiple nuclei.
Limiting Weights is the exercise that stimulates muscles to become stronger. As muscles gain in…. Which of the following processes occurs at the cellular level? Mitochondria is added to aid in ATP production. More calcium is released with each action potential. Larger diameter myochorils are added to each cell.
Why is sarcoplasmic hypertrophy a limitation with size training? It adds more actin and myosin. It decreases glycogen content of the muscle cell. It adds mass that is not able to produce force. It results in greater stores of intracellular fat.
Answer the question(s) below: The 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 mass You may use Google Scholar
Which of the following statements is true? Muscles push on bones; they do not pull The end of the muscle attached to the bone that moves least is the origin The end of the muscle that attaches to the bone that moves the most is the antagonist The synergist is the the muscle that opposes the primary movement
A. nerve cell releases neurotransmitter which stimulates the muscle cell: B. calcium is released from sarcoplasmic reticulum and floods sarcoplasm; C. sarcolemma is permeable to sodium allowing sodium to rush into cell; D. myosin forms cross-bridges to pull actin into the center of the sarcomere; E. sarcolemma depolarizes and conducts an action potential Put them in order
Which of the following is a benefit of regular strength/resistance training? a) all of the above O b) increase in muscular strength and endurance O c) reduced risk of injuries and cardiovascular diseases O d) improved body composition and weight management
With muscular dystrophy, the membrane of muscle cells is destroyed. Given how muscle cells contract, which of the following would fail to happen? Reuptake of acetylcholine by the muscle cells ) Reuptake of acetylcholine by lower motor neurons ) Action potential conduction on muscle cells Action potential conduction on the lower motor neurons
HQ7. Determine whether each label describes skeletal or cardiac muscle.
