A motor unit from a skeletal muscle contains 1500 muscle fibers. Would this muscle be involved in fine, delicate movements or in powerful, gross movements? Explain.

Describe specific functions of skeletal muscle

Anatomy and physiology explain muscle contraction in several distinct steps starting the release of acetylcholine junction.

Describe the three steps (in detail) and the regions where these steps occur required for a skeletal muscle contraction to occur. Diagram(s) is (are) encouraged.

Skeletal muscle is described as striated. What are the lighter, thinner stripes noted under the  microscope?  Group of answer choices troponin actin myosin dystrophin   Rather than innervating individual muscle fibers, motor neurons often innervate two or more muscle fibers. The motor neuron and the muscle fibers it innervates are together called a:  Group of answer choices motor unit myofibril muscle fascicle motor fascia   Fast glycolytic muscle fibers allow for relatively quick ATP energy production by splitting glucose (but eventually leads to fatigue), a process described as:  Group of answer choices fermentation aerobic pathway anaerobic pathway ATP reserve use

How would muscle contractions be affected if skeletalmuscle fibers did not have T-tubules?

Skeletal muscle fibres are very metabolically active and are adapted to create a lot of ATP from aerobic cellular respiration. Additionally, cells require other things to stay alive. Explain how the following three organ systems contribute to allowing a muscle cell to carry out its roles: a) Respiratory system b) Cardiovascular system c) Gastrointestinal system    asap please.

Explain how smooth, graded contractions of a skeletal muscle are produced.

why would skeletal muscle cell need so many nuclei?

Which type of muscle would fatigue faster, one that has many blood vessels or one that has fewer blood vessels? Explain.
