Lawrence Cherono from Kenya won the 2011 Boston Marathon. He probably has a predominance of in the muscle of his legs. fast twitch fibers fat intermediate twitch fibers slow twitch fibers

The disease poliomyelitis (po′le-o-mi′˘e-li′tis) destroys motor neurons, causingloss of muscle function and even flaccid paralysis. Some patients recoverbecause axon branches form from the remaining motor neurons. Thesebranches innervate the paralyzed muscle fibers to produce motor unitswith many more muscle fibers than usual. How does this reinnervation ofmuscle fibers affect the degree of muscle control in a person who hasrecovered from poliomyelitis?

Which of the following does NOT apply to a neuron? O cell body O chromatophilic substance sarcoplasmic reticulum O dendrite synaptic vesicle DELL O.

Every skeletal muscle fiber is supplied by a motorneuron at the NMJ. Watch this video(http://openstaxcollege.org/l/skelmuscfiber) to learnmore about what happens at the neuromuscular junction. (a) What is the definition of a motor unit? (b) What is thestructural and functional difference between a large motorunit and a small motor unit? Can you give an exampleof each? (c) Why is the neurotransmitter acetylcholinedegraded after binding to its receptor?

The diagram below represents the terminal cisterna in a muscle. Name and briefly explainthe function of the structures represented by A, B, C in the regulation of calcium ionsduring muscle contraction

If the cilia of microturbellarians are inhibited, gliding locomotion would cease.   true or false

What allows cardiac muscle and smooth muscle to be excited and contract nearly simultaneously? ganglia intermediate fibers cross bridges motor and plates Gap junctions

How quickly would skeletal muscle fibers fatigue if they were unable to use oxygen to make ATP? approximately 15 seconds  Approximately 30 seconds  Approximately 60 seconds  Approximately 100 seconds approximately 180 seconds

Please help with the labeling of organization of skeletal muscle: Here's what  I found: fascicle muscle fibers nuclei sarcomere sarcolemma myofibril M line I band A band Z disc H zone Thick filament Thin filament perimysium sarcoplasmic reticulum epimysium
