Dendrites


Dendrites are the branched projects of a neuron that act to conduct the electrochemical stimulation received from other neural cells to the body. Electrical stimulation is transmitted onto dendrites by upstream neurons via synpases. Dendrites play a critical role in integrating these synaptic inputs and in determining the extent to which action potentials are produced by the neuron.

Dendrites function as an "antennae" of the neuron and are covered by thousands of synapses. The dendritic membrane under the synapse, the post synaptic membrane, has many specialized protein molecules called receptors. These receptors detect the neurotransmitters in the synaptic cleft.

A nerve cell can have many dendrites which branch many times.dendrites.jpg
