| dendrite | A long, branching outgrowth or extension from a neuron, that carries electrical signals from synapses to the cell body, unlike an axon that carries electrical signals away from the cell body. Each nerve cell usually has many dendrites. This classical definition, however, lost some weight with the discovery of axo-axonal and dendro-dendritic synapses. (29 Sep 1997) |

| dendrites | On of the threadlike extensions of the cytoplasm of a neuron. In unipolar and bipolar neurons, they resemble axons structurally, but typically, as in multipolar neurons, they branch into treelike processes. Dendrites comprise most of the receptive surfaces of a neuron. (12 Dec 1998) |
| apical dendrite | The dendritic process extending from the apex of a pyramidal cell of the cerebral cortex toward the surface. Synonym: apical dendrite. (05 Mar 2000) |
