The definition of the soma is fuzzy, as there is no clear line demarcating the soma of the labeled neurons and the origin of the dendrites and axon. Thus, the morphometric analysis of the neuronal soma is highly subjective.

Signals from one nerve cell to another are transferred across special zones of contact between the neurons that are known as synapses. The mechanism by which neurons communicate with each other is called synaptic transmission. Chemical neurotransmission is the most prevalent mechanism of communication between neurons. It involves release of chemical substances (neurotransmit-ters) from the presynaptic terminals of neurons, which excite or inhibit one or more postsynaptic neurons.
The human brain consists of about 1011 nerve cells.

Chapter 2 101 sensory neuron.
A neuron that detects changes in the external or internal environment and sends information about these changes to the central nervous system. motor neuron.
A neuron located within the central nervous system that controls the contraction of a muscle or the secretion of a gland. interneuron.
A neuron located entirely within the central nervous system. central nervous system/CNS.
The brain and spinal cord. peripheral nervous system/PNS.
That part of the nervous system outside the brain and spinal cord, including the nerves attached to the brain and spinal cord.
The nerve cells of the central and peripheral nervous systems are called neurons. Most neurons have three parts; an axon, a cell body or soma, and dendrites.

The nerve cells of the central and peripheral nervous systems are called neurons. Most neurons have three parts; an axon, a cell body or soma, and dendrites. All neurons have one soma and one axon, but while some neurons have many dendrites, others have none.
Neurons vary in size; the smallest have a diameter of 5 microns while the largest are approximay 100 microns in width.
Soma. The soma is the cell body of the neuron that contains the nucleus and much of the other 'life' of the neuron. Dendrites and axons reach out from the soma.
How we change what others think, feel, believe and do.
Neurons are the basic cells of the nervous system. They act to process and transmit information around the system.
Neurons make up about half the cells of the CNS. The rest, in particular glia, are provide additional supporting roles.
The soma is the cell body of the neuron that contains the nucleus and much of the other 'life' of the neuron.
Dendrites and axons reach out from the soma to connect with other neurons.
Dendrites stretch out from the soma much like branches from a tree, breaking down into smaller branches and twigs (dendrite is the Greek word for 'tree').
