Serotonin released from the cell body is taken up by glia and Instead, neurons release serotonin from their soma, dendrites and axon.
Serotonin, a modulator of multiple functions in the nervous system, is released predominantly extrasynaptically from neuronal cell bodies, axons and dendrites. This paper describes how serotonin is released from cell bodies of Retzius neurons in the central nervous system (CNS) of the leech, and how it affects neighbouring glia and neurons. The large Retzius neurons contain serotonin packed in electrodense vesicles. Electrical stimulation with 10 impulses at 1 Hz fails to evoke exocytosis from the cell body, but the same number of impulses at 20 Hz promotes exocytosis via a multistep process.
The cell body of a neuron. contains the nucleus, and provides the life processes of the Bipolar=a neuron with one axon and one dendrite attached to its soma.

cells in the brain that process,integrate and transmit information recieved from the nervous system(s).
the cell body of a neuron. contains the nucleus, and provides the life processes of the entire cell. also, integrates the information recieved by the dendrites.
treelike structure attached to the soma of a neuron.
Without these neurons working and carrying messages throughout our body we would feel and be Soma (cell body), Contains the nucleus (brain) of the cell.
Right now, ask yourself how you feel; emotionally and physically. For example, at the moment I am writing this I am happy because I am looking forward to some ribs tonight from this great BBQ place called Q's. At the same time, I am anxious because I have to teach in five days when school starts for the year. My left shoulder is sore because I hurt it last year in a collision at home plate in the Westchester Temple softball league (Jewish men and softball is a dangerous combination- if you want to see the championship video recap for Larchmont Temple- my team click here ).
Neurons are nerve cells that transmit nerve signals to and from the brain at up to 200 mph. The neuron consists of a cell body (or soma) with branching dendrites.
The brain and spinal cord are made up of many cells, including neurons and glial cells. Neurons are cells that send and receive electro-chemical signals to and from the brain and nervous system. There are about 100 billion neurons in the brain. There are many more glial cells; they provide support functions for the neurons, and are far more numerous than neurons. There are many type of neurons. They vary in size from 4 microns (.004 mm) to 100 microns (.1 mm) in diameter. Their length varies from a fraction of an inch to several feet.
Some of the smallest neurons have cell bodies that are only 4 microns wide. is by the number of extensions that extend from the neuron's cell body (soma).

The human body is made up of trillions of cells. Cells of the nervous system, called nerve cells or neurons, are specialized to carry "messages" through an electrochemical process. The human brain has approximay 100 billion neurons. To learn how neurons carry messages, read about the action potential.
Neurons come in many different shapes and sizes. Some of the smallest neurons have cell bodies that are only 4 microns wide. Some of the biggest neurons have cell bodies that are 100 microns wide.
