Explanation:
motor neuron is the neuron that have it's connection to a muscle at the neuromuscular junction,. At his junction, a synaptic cleft that has a motor end plate is formed by the activity of the terminal called "synaptic terminal". Diffusion of the acetylcholine across the synaptic cleft then occur which result to the sarcolemma been depolarized, as a result of the depolarization there is a output of Ca2+ and muscle contraction
The effect that botox have on the neuromuscular junction and its function is that there is interaction between Botox and neural transmission which obstruct the acetylcholine to be released, which result to paralysis of muscle.
