Detailed explanation-1: -Neurons have a membrane featuring an axon and dendrites, specialized structures designed to transmit and receive information. Neurons release chemicals known as neurotransmitters into synapses, or the connections between cells, to communicate with other neurons.
Detailed explanation-2: -Dendrite – The receiving part of the neuron. Dendrites receive synaptic inputs from axons, with the sum total of dendritic inputs determining whether the neuron will fire an action potential.
Detailed explanation-3: -Two mechanisms have evolved to transmit nerve signals. First, within cells, electrical signals are conveyed along the cell membrane. Second, for communication between cells, the electrical signals generally are converted into chemical signals conveyed by small messenger molecules called neurotransmitters.
Detailed explanation-4: -Interneurons. Interneurons are neural intermediaries found in your brain and spinal cord. They’re the most common type of neuron. They pass signals from sensory neurons and other interneurons to motor neurons and other interneurons.
