DENDRITE
| Pronunciation (US): |  | (GB): | |
I. (noun)
Sense 1
Meaning:
Short fiber that conducts toward the cell body of the neuron
Classified under:
Hypernyms ("dendrite" is a kind of...):
nerve fiber; nerve fibre (a threadlike extension of a nerve cell)
Holonyms ("dendrite" is a part of...):
nerve cell; neuron (a cell that is specialized to conduct nerve impulses)
Derivation:
dendritic ((neuroscience) of or relating to or resembling a dendrite)
Context examples:
In addition, the program learned to differentiate between axons and dendrites, which are two specific types of extensions on neurons.
(Scientists teach computers how to analyze brain cells, National Institutes of Health)
A long, branching outgrowth or extension from a neuron, that carries electrical signals from synapses to the cell body; any structure that resembles a dendrite.
(Dendrite, NCI Thesaurus)
A synapse between dendrites of two neurons.
(Dendrodendritic Synapse, NCI Thesaurus)
Activation of CFs, which make multiple synaptic contacts on proximal dendrites, also via AMPA receptors, opens voltage-gated calcium channels (VGCCs) and causes a generalized influx of calcium.
(Long-Term Depression Pathway, NCI Thesaurus/KEGG)
The olfactory bulb contains several types of nerve cells including the mitral cells, on whose dendrites the olfactory nerve synapses, forming the olfactory glomeruli.
(Olfactory bulb, NLM, Medical Subject Headings)
A nerve cell with several processes, usually an axon and three or more dendrites.
(Multipolar Neuron, NCI Thesaurus)
They send to the surface of the epithelium apical dendrites with non-motile cilia from which project odorant receptor molecules.
(Murine Olfactory Receptor Neurons, NLM, Medical Subject Headings)
The third layer of the cerebral cortex, composed of an inner zone of medium sized pyramid-shaped cells with a single apical dendrite extending outward toward the surface and several dendrites extending inward and an outer zone of larger pyramid shaped cells whose dendrites and axons extend beyond this layer.
(External Pyramidal Cell Layer of the Cerebral Cortex, NCI Thesaurus)
Most negative electrodes in current lithium-ion batteries are made of graphite, which has a high energy density, but when charged at high rates, tends to form spindly lithium metal fibres known as dendrites, which can create a short-circuit and cause the batteries to catch fire and possibly explode.
(New class of materials could be used to make batteries that charge faster, University of Cambridge)
A typical neuron consists of a cell body, containing the nucleus and the surrounding cytoplasm (perikaryon); several short radiating processes (dendrites); and one long process (the axon), which terminates in twiglike branches (telodendrons) and may have branches (collaterals) projecting along its course.
