WebThe damage to the protective covering and also to the nerves disrupts the smooth flow of nerve impulses. As a result, messages from the brain and spinal cord going to other parts of the body may be delayed and have trouble reaching their destination – causing the symptoms of MS. - symptoms/ Web2 days ago · A synapse is a junction between the nerve cell and its target tissue. In humans, synapses are chemical, meaning that the nerve impulse is transmitted from the axon ending to the target tissue by the chemical substances called neurotransmitters (ligands). If a neurotransmitter stimulates the target cell to an action, then it is an excitatory ...

WebAn electrical impulse cannot directly cross the gap so a different mechanism has to be used. An electrical nerve impulse travels along the axon. of the first neuron (presynaptic neuron). WebNeurotransmitters are how we communicate between one cell and the next. Synapses between neurons are either excitatory or inhibitory – and that all comes down to the neurotransmitter released. Excitatory neurotransmitters cause the signal to propagate - more action …
