Axons must have structures that make and secrete the molecules, and muscles cells must have receptors that recongnize these molecules is true about structures of axons and muscle cells in order for the nerve impulses to stimulate muscle contractions
Step-by-step explanation:
The axon manages to wait for the identical broadness for most of its length and doesn't have spines. The axon emerges from the cell body at a specific region called the axon hillock. Several axons are comprised of a unique insulating material called myelin, which improves them dispatch the nerve impulse immediately. When an activity potential travels down an axon and arrives at the axon terminal, it triggers the release of neurotransmitter from the presynaptic cell. Neurotransmitter molecules cross the synapse and bind to membrane receptors on the postsynaptic cell, conveying an excitatory or inhibitory signal.
