A motor neuron‚ a nerve ending that is attached to a muscle fiber in Petzold’s huge bicep‚ sends a message to contract. This message goes to the neuromuscular junction‚ which is the connection between the actual nerve fiber and muscle fiber. As the message to contract reaches the terminals a neurotransmitter‚ a chemical messenger for the body‚ is released into the gap between the terminal end‚ and the sarcolemma and motor end plate called the synaptic cleft. The particular neurotransmitter is called
