Qu'est-ce (qui) est dendrite - définition

NEURON PROJECTION THAT HAS A SHORT, TAPERING, OFTEN BRANCHED, MORPHOLOGY, RECEIVES AND INTEGRATES SIGNALS FROM OTHER NEURONS OR FROM SENSORY STIMULI, AND CONDUCTS A NERVE IMPULSE TOWARDS THE AXON OR THE CELL BODY
Dendrites; Dendrons; Dendritic branch; Dendritic arborization; Dendritic branching; Dendritic tree
  • The neuron contains dendrites that receives information, a cell body called the soma, and an axon that sends information. Schwann cells make activity move faster down axon. Synapses allow neurons to activate other neurons. The dendrites receive a signal, the axon hillock funnels the signal to the initial segment and the initial segment triggers the activity (action potential) that is sent along the axon towards the synapse.

Dendrite         
·noun A stone or mineral on or in which are branching figures resembling shrubs or trees, produced by a foreign mineral, usually an oxide of manganese, as in the moss agate; also, a crystallized mineral having an arborescent form, ·e.g., gold or silver; an Arborization.
Dendrite         
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. Electrical stimulation is transmitted onto dendrites by upstream neurons (usually via their axons) via synapses which are located at various points throughout the dendritic tree.
dendrite         
['d?ndr??t]
¦ noun
1. a short extension of a nerve cell conducting impulses to the cell body.
2. a crystalline mass with a branching, tree-like structure.
a natural tree-like marking on a rock or mineral.
Derivatives
dendritic d?n'dr?t?k adjective

Origin
C18: from Fr., from Gk dendrites 'tree-like'.

Dendrite

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. Electrical stimulation is transmitted onto dendrites by upstream neurons (usually via their axons) via synapses which are located at various points throughout the dendritic tree.

Dendrites play a critical role in integrating these synaptic inputs and in determining the extent to which action potentials are produced by the neuron.
