Bipolar neurons have only one axon and one dendrite with the soma between them. There are probably very few, if any, neurons that contain only a single axon and dendrite. However, the concept is useful because some neurons behave as if they only had a single axon and dendrite. These neurons, called bipolar neurons because their cell body sits in between the axon and dendrite (giving the neuron two "poles"), are abundant in the nervous system. One very important type of bipolar neuron occurs in the retina, and is responsible for how we process light at an early level.
what do you call a ordinary body cell? the most cells are determined on a single propose. They have different rezecptors, membranproteins and so on. So a neuron is special, but all cells are special.
unidirectional transmissionSignals pass from presynaptic to postsynaptic neurone since: synaptic vesicles are only found in presynaptic neurone and receptors for neurotransmitter are only found in postsynaptic neurone.intterconnection between nerve pathwaysOne neurone may receive signal from many synapses from different presnaptic neurones. This allows a wide range of actions in response to a stimulus.memory and learningNeurones involved are linked by new synapses.

A neuron is like a relay switch - it receives signals from other neurons and depending on the nature of the signals, the neuron may then 'fire' a signal of its own, stay silent, or become inhibited. This is like binary code - i.e.,"on" and "off" states. A neuron can oscillate between these states in a variety of frequencies. So the range of computations that even a single neuron can perform is impressive. Now, consider that this sort of thing is happening billions of times every second all throughout the nervous system and you can intuitively grasp just how complex the patterns of signals would become. In fact, somewhere in those patterns is what we would call our 'mind' and our 'intelligence' and so on. And this is all because of a large collection of neurons (~100 billion at birth) relaying signals to each other through a multitude of pathways (trillions).
The rule in Biology about closed off organisms dying is known as Kin selection.
A single brain neuron is kind of strong. It is naturally stronger working together with all neurons in that area. Neurons have either it is all the way on or all the way off.
The process of lengthening and branching off is known as dendritic growth. This occurs in various biological processes, such as the growth of neurons in the brain and the formation of tree branches.
Sensory pathways contains these pseudounipolar neurons and bipolar neurons. The pseudounipolar neurons have dendrites fused with axon and they are for somatic senses. The bipolar neurons have two relatively equal fibres extending off their central cell body and they are for smell & vision.
Unipolar Sensory Neurons: large myelinated neurons with the cell body off to one side of the single dendritic-axon process. Multipolar Motor Neurons: large myelinated neurons that have many dendrites off the cell body and an axon that may branch to effect many effectors.
A single number, such as 1608040, does not have a rule.
If you take your hand off a chess piece after touching it, you must move that piece if it is legal to do so. This is known as the "touch-move" rule in chess.

The Mercury Mountaineer is a classy SUV. Some models have been known to have faulty alarms that either go off randomly or fail to go off when they should.
There are no settings. They are either on or off. You can not adjust them.There are no settings. They are either on or off. You can not adjust them.
A hockey penalty occurs if a player breaks a rule AND if the breaking of that rule is punishable by either a minor, major, misconduct, match misconduct, or match penalty. Not all rule infractions are punishable by a penalty. A few that are not: hand pass, icing, off-sides, and high-sticking the puck.
