Each axon terminal contains thousands of membrane-bound sacs called vesicles, which in turn contain thousands of neurotransmitter molecules each. Neurotransmitters are chemical messengers which relay, amplify and modulate signals between neurons and other cells.
Synaptic Transmission. Introduction Neurons receive information from sensory organs, send information to motor organs, or share information with other neurons. The process of communicating information is very similar, whether it is to another neuron or to a muscle or gland cell.However, by far the largest number of neuronal connections is with other neurons. The rest of this tutorial therefore focuses on inter-neuronal communication.he transmission of information is accomplished in two ways: 1  Electrically: the neuron is directly adjacent to other neurons. 2  Chemically: there is a space (the synaptic cleft) between the axon terminus and the adjacent neuron.
