- Men are generally stronger than women because they typically have larger bodies, and a more significant proportion of their total body mass is made up of muscle. However, when strength is expressed per unit of the cross-sectional area of muscle tissue, men are only 1-2% stronger than women in the upper body and equal to women in the lower body. Explain two factors that explain these disparities.arrow_forwardOutline the contractile process. Use a step-by-step format illustrating the entire process, beginning with the nerve impulse reaching the neuromuscular junction.arrow_forwardCompare and contrast the connective tissue types of loose, cartilage, dense, bone, and blood. Explain, in detail, the process of a muscle contraction at a microscopic level (including the sliding filament model). Please make sure responses are in your own words as possible as you can. Thanks for the help.arrow_forward
- Compare the inner layer of smooth muscle with circumferentially running muscle cells,to the outer layer of longitudinally running fibres that have been sectioned transversely, which layer is easy to distinguisharrow_forwardTo build individual muscle strength and muscle girth (i.e. bulk up), it is best to: O a) do resistance exercises for each muscle at least 6 days per week b) use medium resistance with medium number of repetitions O c) use heavy resistance with few repetitions for multiple sets d) use light resistance with many repetitionsarrow_forwardWhich 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.arrow_forward
- 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 change 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. Describe some activities you could recommend to an elderly patient to stay active to help them maintain muscle mass.arrow_forwardIn 3-4 sentences compare and contrast the various types of muscle contraction and be able to give at least an example for each. What type of contraction causes change in length of muscle fibers? Which type does not result to movement?arrow_forward
