stimulus event an electrical signal is propagated through the length of the axon of a motor nerve. This electrical signal‚ also propagated through ion channels‚ causes the opening of calcium ion channels. These calcium ion channels ‚ guided by the membrane potential‚allow calcium ions to diffuse into the axon terminal of the motor neuron. As more calcium ions travel into the axon of the motor neuron‚ synaptic vesicles begin to form around acetylcholine and leave the axon of the motor neuron‚ entering the

The dendrites receive neurotransmitters from the synapses that connect to it and if enough are present‚ an action potential is caused which then travels down the axon to the terminal buttons also known as synapses. There are electrical and chemical synapses in the body although the vast majority are chemical. Electrical synapses are located in the retina and in some

But regardless‚ the most of the synapses in vertebrates are chemical. When a nerve impulse comes to a chemical synapse‚ neurotransmitters‚ which are pointer substances‚ are issued from the nerve terminal and diffuse to the membrane of the target cell. The unfastening of these passages
