Although neurons are very diverse and there are exceptions to nearly every rule, it is convenient to begin with a schematic description of the structure and function of a "typical" neuron. A typical neuron is divided into three parts: the soma or cell body, dendrites, and axon. The soma is usually compact; the axon and dendrites are filaments that extrude from it. Dendrites typically branch profusely, getting thinner with each branching, and extending their farthest branches a few hundred micrometres from the soma. The axon leaves the soma at a swelling called the axon hillock, and can extend for great distances, giving rise to hundreds of branches. Unlike dendrites, an axon usually maintains the same diameter as it extends. The soma may give rise to numerous dendrites, but never to more than one axon. Synaptic signals from other neurons are received by the soma and dendrites; signals to other neurons are transmitted by the axon. A typical synapse, then, is a contact between the axon of one neuron and a dendrite or soma of another. Synaptic signals may be excitatory or inhibitory. If the net excitation received by a neuron over a short period of time is large enough, the neuron generates a brief pulse called an action potential, which originates at the soma and propagates rapidly along the axon, activating synapses onto other neurons as it goes.

∙ 14y agoOne of the cells that constitute nervous tissue, that have the property of transmitting and receiving nervous impulses
and that are composed of somewhat reddish or grayishprotoplasm with a large nucleus containing a conspicuous nucleolus, irregular cytoplasmic granules, and cytoplasmic processes.
which are highly differentiated frequently as multiple dendrites or usuallyas solitary axons and which conduct impulses toward and away from the nerve cell body.!

What do neurons look like with cocaine injected and stressed?
Nicole is ugly.
What is neurospora?
This is a type of fungi whose spores have striations that look like neurons (nerve cells).
What will a person's neurons look like after a year with the disease ALD?
wish i knew i need the same thing
Do all neurons look the same?
yes.
What advantage to vertebrates neurons like lions have over early more primitive invertebrates neurons like insects?
Mocock.
What would life be like without neurons?
Neurons are the basic constituent of brain tissues. Without neurons person will be unable to do anything, to sense anything or to thing anything. Life would be extremely hard to imagine without the neurons. Neurons are part of nervous system.
What is the role of the neuron?
Neurons are like they brains messengers. The brain figures out what needs to be done and the neurons tell they body to do it.
What do the lower neurons do?
You are probably speaking of "lower motor neurons." These are neurons that send information from the spinal cord to the muscles of the body & they travel within all most of the nerves of the body (like sciatic, median, etc). These neurons are controlled by "upper motor neurons" and control your muscles to allow you to be able to move.
How long does it take for neurons to connect?
The neurons will connect in less than a second. They will connect immediately Almost like the speed of light.
What are neurons called that detect stimuli in the skin and eye?
sensory neurons
Are cells the same as neurons?
A neuron is a type of cell, but not all cells are neurons.(Just like a Dalmatian is a type of dog, but not all dogs are Dalmatians.)Neurons are mostly found in the brain and spinal column.
Are neurons that relay impulses from sensory neurons to motor neurons?
Sensory Neurons
