WebApr 8, 2024 · Neuron Parts and their Functions: Dendrites: These are tree-like extensions at the beginning of the neuron and help in increasing the area of the cell body. Most neurons have dendrites going outwards away from the cell body. They receive information from other neurons and transmit electrical stimulation to the soma or the cell body of the …

WebConcepts and definitions. Axon – The long, thin structure in which action potentials are generated; the transmitting part of the neuron. After initiation, action potentials travel down axons to cause release of neurotransmitter. Dendrite – The receiving part of the neuron. Dendrites receive synaptic inputs from axons, with the sum total of dendritic inputs … Dendrites (from Greek δένδρον déndron, "tree"), also dendrons, are branched protoplasmic extensions of a nerve cell that propagate the electrochemical stimulation received from other neural cells to the cell body, or soma, of the neuron from which the dendrites project.
