Detailed explanation-1: -Neurons are the cells that pass chemical and electrical signals along the pathways in the brain. They come in many shapes and sizes. Their shapes and connections help them carry out specialized functions, such as storing memories or controlling muscles.
Detailed explanation-2: -The transfer of information from neuron to neuron takes place through the release of chemical substances into the space between the axon and the dendrites. These chemicals are called neurotransmitters, and the process is called neurotransmission. The space between the axon and the dendrites is called the synapse.
Detailed explanation-3: -Different neurons have different jobs. For example, sensory neurons send information from the eyes, ears, nose, tongue, and skin to the brain. Motor neurons carry messages away from the brain to the rest of the body to allow muscles to move.
Detailed explanation-4: -Neurons communicate via both electrical signals and chemical signals. The electrical signals are action potentials, which transmit the information from one of a neuron to the other; the chemical signals are neurotransmitters, which transmit the information from one neuron to the next.
