Just How Powerful Are Muscles?
Thursday, November 16, 2006
Muscles some in antagonistic pairs -- one muscle contracts to move a joint one way, and another serves to move it the other way. Your muscles are so strong that if both muscles in one of your antagonistic pairs contracted at the same time, they would break the bone they were connected to. Thank goodness for nerve impulses that make this impossible to happen. But should your electrical signals fail you...as they might during electrocution...
Just a little anatomy trivia.
