Motor end plates are associated with muscle contraction definitely, and I would say also <em>neuron transmitter, </em>although I'm not sure about that one.
I think it is A or C
Thanks
Answer:
The kind of muscle contraction that occurs when you try to lift a box but it's to heavy and it can't be moved from the floor is called: Isometric Contraction.
Explanation:
Isometric contraction consists of having a muscle activated but to maintain it at a constant length, instead of shorten or lengthen it.
