Predict the consequences if presynaptic action potentials In an axon release insufficient acetylcholine to depolarize a skeletal muscle fiber to threshold

The consequences if presynaptic action potentials In an axon release insufficient acetylcholine to depolarize a skeletal muscle fiber to threshold

Explanation:

When an action potential reaches a neuromuscular junction, it causes acetylcholine to be released into this synapse. The acetylcholine binds to the nicotinic receptors concentrated on the motor end plate, a specialized area of the muscle fibre's post-synaptic membrane.

Acetylcholine is the neurotransmitter used at the neuromuscular junction—in other words, it is the chemical that motor neurons of the nervous system release in order to activate muscles. ... In the brain, acetylcholine functions as a neurotransmitter and as a neuromodulator.
