Question

Which of the following must be true about the structures of axons and muscle cells in order for nerve impulses to stimulate muscle contraction?. a- Axons and muscle cells must both have structures that make and secrete the same small molecules.. b- axons and muscle cells must both have receptors that recognize the same small molecules.. c- Axons must have structures that make and secrete molecules, and muscle cells must have receptors that recognize these molecules.. d-Muscle cells must have structures that make and secrete molecules, and axons must have receptors that recognize these molecule

Answer 1

the one that is true about the structures of axons and muscle cells in order for nerve impulses to stimulate muscle contraction is : C. Axon must have structures that make and secrete molecules, and muscle cells must have receptors that recognize these molecules.
and beside that, our muscle has the ability to bind that signaling molecule

Hope this helps

Answer 2

c- Axons must have structures that make and secrete molecules, and muscle cells must have receptors that recognize these molecules.
