Detailed explanation-1: -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. Spine – The small protrusions found on dendrites that are, for many synapses, the postsynaptic contact site.
Detailed explanation-2: -Dendrites provide an enlarged surface area to receive signals from the terminal buttons of other axons, and the axon also commonly divides at its far end into many branches (telodendria) each of which ends in a nerve terminal, allowing a chemical signal to pass simultaneously to many target cells.
Detailed explanation-3: -Dendrites receive input from many other neurons and carry those signals to the cell body. If stimulated enough, a neuron fires an action potential-an electrical impulse that then stimulates other neurons. Large networks of these neurons communicate with each other to generate thoughts and behavior.
Detailed explanation-4: -Axon hillock: Once a signal is received by the dendrite, it then travels to the cell body. The cell body contains a specialized structure, the axon hillock that “integrates” signals from multiple synapses and serves as a junction between the cell body and an axon.
Detailed explanation-5: -Terminal Buttons and Synapses The terminal buttons are located at the end of the neuron and are responsible for sending the signal on to other neurons. At the end of the terminal button is a gap known as a synapse. Neurotransmitters are used to carry the signal across the synapse to other neurons.
