Dendrite
* Some dendrites also have even smaller spines which serve as extremely sensitive receptors.
* Some dendrites are part of brains
  - cortexes
  - neocortexs
  - neurons
* are also the target of numerous inhibitory synapses
  - branches in axons
  - cellular projections whose primary function is to receive synaptic signals
  - devoid of voltage dependent channels necessary to produce an action potential
  - extended, contracted and moved between different pairs of keratinocytes continuously
  - extensions from the cell
* are extensions of neurons that receive signals from other neurons
  - the nerve cell membrane that receive the input from other nerve cells
  - hair-like extensions of the soma which act like input channels
  - like the trees of the mind, growing like poplars in the sun
  - more spiny on mature hippocampal neurons when synapses are inactivated
  - nerve fiber
  - part of nerve cells
  - really 'cell phones' which enable neurons to talk to each other
  - relatively short in length in comparison with a neuron's axon
  - short, thick processes which branch out of the soma in a tree like manor
  - shorter attachments that receive nerve impulses
  - some tens of microns in length
* are the dark short branching fine lines seen near the top and along the main crack
  - necessary and sufficient structures for human learning
  - part of the neuron that receives incoming signals via a set of branched fibers
  - primary receiving sites for incoming irritation in most neurons
  - receptive portions which recieves the impulses
  - treelike structures that crystals form as they grow
  - usually more numerous, shorter and more branched than axons
* arise from the neuronal cell body.
* bring information to the cell body and axons take information away from the cell body
  - and axons take information away from thecell body
* carry impulses from the environment or other neurons to the cell body
  - the signals out to the various synapses, and the cycle repeats
* conduct electrical signals received from other neurons to the parent neuron's cell body
  - impulses to cell body
* consist of a chain of segments without bifurcation.
* enable connections with other neurons at points called synapses.
* extend from the cell body after the completion of migration
  - and send nerve impulses to other neurons
* extending from the cell body of the neuron give the appearance of arborization.
* form a network between the neurons
  - leakage paths that quickly drain a battery after a recharge
* grow as a result of stimulation from and interaction with the environment.
* have many branches, like a tree
  - terminal bulbs, arboral pattern
* includes cell membranes
  - chromosomes
  - corpi
  - cytoskeletons
  - lobes
  - nuclei
  - plasma membranes
  - sections
  - vacuoles
* is fiber
  - fibre
* look like the branches of a tree and receive messages for the cell.
* receive impulses that are conducted to the cell body.
* receive information from another cell and transmit the message to the cell body
  - other neurons or from sense organs
  - nerve impulses from other neurons or from sensory receptors
  - neuronal impulses and transmit to the cell body
* serve as input devices to the neuron.
* take information to the cell body.
* then connect and communicate with other neurons.
* transmit dendron.
* usually branch close to the cell body.
+ Nerve, Nerve Structure: Anatomy of the nervous system
  * Nervous system contains neurons and cells called glia. Glia cells keep the neurons safe and healthy. Neurons take messages to and from the CNS to the rest. The dendrite and axon are fibers that go out from the cell body. Axons take information 'away from' the cell body. Dendrites take information to the cell body.
