In a skeletal muscle cell, this neurotransmitter is acetylcholine: neurotransmitter diffuses across the synaptic cleft and binds to receptors, binding of neurotransmitter to receptor activates signal transduction pathways. Variation in signal transmission: chemical synapsis, electrical signal is converted into a neurotransmitter. It then diffuses across the synapse: then binds to receptors, unidirectional, slower (short delay), greater diversity and complexity of signals. Variation in signal transmission: diversity in neurotransmitters, diversity in receptors, diversity in synapse structure, diversity in synapse location, these all together create a huge diversity in neuron form and function.
