Answer:
myofibril bulbous end of axon and skeletal muscles fibres.
Explanation:o
It represents the chemical synapse of the axon bulbous ends of the motor neuron ( motor end plate) and the skeletal Muscle fibres.
The influx of calcium ions into the bulbous ends leads to the fusion and empty of the vesicles containing neurotransmitters into the synaptic cleft.
The Neurotransmitters binds to the receptors on the muscles membrane to allow the transmission of action potential ( PSIP or PSEP)across the synaptic gap to the muscles fibers to initiate their contraction or relaxation.
