Question 16 of 30   0.0/ 3.33 Points
Which of the following is true about skeletal muscles?

   

   A. They have the same origin and insertion point    
   

   B. They work in antagonistic pairs    
    

   C. They get longer when they contract    
   

   D. They produce blood cells

Answer Key: B
Feedback: When a muscle contracts, it shortens, and the tendon pulls on the bone. Therefore, muscles can only pull a bone; they cannot push it. Because of this, skeletal muscles must work in antagonistic pairs. If one muscle of an antagonistic pair flexes the joint and bends the limb, the other one extends the joint and straightens the limb.

Question 29 of 30   0.0/ 3.33 Points
Why does a given muscle’s threshold of stimulation change as its workload changes?


the stimulation threshold of a miscle has to be able to change as more or less is demanded of it, if it remained constant it would fail

Model Short Answer: Those muscles that respond to a higher workload have more bundles. This requires more activation to stimulate the bundles.
Question 30 of 30   0.0/ 3.33 Points
Define two of the following: “all or none” response, oscilloscope, tendon


"All or none": When the fibers are exposed to stimuli from the nevous sustem each individual muscle fiber will contract either completely or not at all

Tendon: a band of fibrous connective tissue that usually connects bone and is capable of withstanding tension

Model Short Answer: a. “All or none” response—when exposed to a stimuli, the muscle fiber will either contract all at once or not at all.
b. Oscilloscope—provides a stimulus and measures the twitch of a muscle
c. Tendon—bands of tissues that connect bones and muscles.
