dendrite

 [den´drīt]
any of the threadlike extensions of the cytoplasm of a neuron; they typically branch into treelike processes, and compose most of the receptive surface of a neuron.
Dendrites in a multipolar neuron. From Dorland's, 2000.

den·drite

(den'drīt),
1. One of the two types of branching protoplasmic processes of the nerve cell (the other being the axon). Synonym(s): dendritic process, dendron, neurodendrite, neurodendron
2. A crystalline treelike structure formed during the freezing of an alloy.
[G. dendritēs, relating to a tree]

dendrite

(dĕn′drīt′)
n.
1.
a. A mineral crystallizing in another mineral in the form of a branching or treelike mark.
b. A rock or mineral bearing such a mark or marks.
2. A branched protoplasmic extension of a nerve cell that conducts impulses from adjacent cells inward toward the cell body. A single nerve may possess many dendrites. Also called dendron.

dendrite

[den′drīt]
Etymology: Gk, dendron, tree
a slender branching process that extends from the cell body of a neuron and that is capable of being stimulated by a neurotransmitter. Each neuron usually possesses several dendrites, which receive synapses where chemical transmission occurs from axons to dendrites (or an axon, in the case of unipolar neurons). The number of dendrites and thus the number of synapses varies with the functions of a neuron. Also called cytodendrite. Compare axon.

DENDRITES
A short spike-shaped cell process. The term usually refers to the branched, tapering cell processes of neurons. Incoming synapses form on the neuronal dendrites, which often arborize, sometimes extensively. Synonym: dendron See: illustration

extracapsular dendrite

A dendrite of a neuron of autonomic ganglia that pierces the capsule surrounding the cell and extends for a considerable distance from the cell body.

intracapsular dendrite

A dendrite of a neuron of autonomic ganglia that branches beneath the capsule of the ganglion, forming a network about the cell body.
dendritic (den-drit'ik), adjective

dendrite

One of the usually numerous branches of a nerve cell that carry impulses toward the cell body. Dendrites allow the most complex interconnection between nerve cells, as in the brain, so that elaborate control arrangements over the passage of nerve impulses are made possible. Recent research suggests that sections of some dendrites can function independently.

dendrite

or

dendron

a projection from the nerve cell which branches and conducts impulses towards the cell body from other neurones with which they have SYNAPSES. See NEURON, AXON and Fig. 228 .

den·drite

1. One of the two types of branching protoplasmic processes of the nerve cell.
Synonym(s): neurodendrite.

dendrite (den´drīt),

n 1. the fingerlike projections formed during the solidification of crystalline materials.
n 2. a branched, treelike protoplasmic process of a neuron that carries nerve impulses toward the cell body. See also axon.
