Agonist/Antagonist muscle pairs (quick question)

[scilearner]

agonist/antagonist muscle pairs. Let's say agonist flexes the finger. When agonist get paralyzed why does the finger stay in an extended position?

 

Ok I know this is obvious it is acting unopposed but my question is for the finger to stay in an extended position does the paralyzed person have to extend his finger first. What I mean is does the finger extend immediately after paralysis or does the person have to physically extend it once and then he can't flex it again so it stays that way.

 

When my hand is at rest my fingers are flexed? What is the reason for this. How does this flexion occur auto?

 

Thanks

The short answer is that if the finger is flexed when the flexor is paralyzed, it'll extend once (when the person activates the extensor) and then stay that way.
