44. What are ryanodine receptors? 45. What are the steps of muscular contraction - from the neuromuscular junction to the sarcomere?

2. You cut the axon of a single motor neuron innervating the biceps muscle. Which of the following is true?a. The biceps muscle will no longer be able to contractb. Only one muscle fiber in the biceps will be unable to contractc. All muscle fibers in the biceps innervated by that motor neuron will no longer be able to contractd. There will be no effect since each muscle fiber is innervated by multiple motor neurons 3. Which of the following will produce the LARGEST force of twitch contraction? Explain your answer.a. Stimulation of all alpha motor neurons in a muscleb. Stimulation of all alpha motor neurons plus all gamma motor neurons in a musclec. Both stimulations will cause a similar force of twitch contraction   4. A patient, like Ian Waterman, who has lost all muscle proprioceptor neurons. Which reflexes will be absent inthis patient? 5. You have found a new type of sensory neuron that senses ammonia. If this sensory neuron worked like thesensory neurons we studied in class, how…

How does an event (action potential) on the outside of a muscle fiber trigger the contractile process on the inside?

What is the effect of centrally acting skeletal muscle relaxants on the body, and what safety precautions are related to their use?

5..List five proteins of the myofilaments and describe theirphysical arrangement. Asap

Which is more resistant to fatigue, cardiac muscle or skeletal muscle? What is the anatomical basis for this difference, and why is it important?

1. Describe a skeletal muscle fiber's microanatomy, including structures such as the sarcolemma, sarcoplasmic reticulum, transverse tubules, myofibrils (sarcomere structure).

2.   This is not and will not be graded
