Neuron: A nerve cell; consists of cell body, dendrites, and axon.
Dopamine autoreceptors are present at the mesostriatal neuron terminals that control dopamine synthesis and release, and on the cell body that controls the impulse firing rate.
Nerve: The nerve is made up of the nerve cell body and the axon.
The other, the amyloid precursor protein (APP) is a molecule that is packaged and delivered from the cell body to synapses, which is being cut up by cleavage enzymes into its active components on the way (Konrad Beyreuther, Universitat Heidelberg, Heidelberg, Germany; Christian Haass, Ludwig-Maximilians University, Munich, Germany).
The nucleus, which is found inside the cell body and contains genes composed of deoxyribonucleic acid (DNA), helps to regulate the cell's activities in response to signals from outside and inside the cell.
However, receptors located close to the base of an axon--which is where it meets the cell body and where nerve impulses originate-had a larger influence on the threshold than did receptors farther away.
Stringy dendrites carry the message toward the neuron's cell body.
The sperm cells are rather simple, representing a roundish or slightly elongated cell body devoid of a flagellum, but provided with one, rarely two, flat extensions which fold onto the cell body (Fig.
GFP was expressed in the cell body and also extensively in neuronal processes extending laterally away from the ventricular wall (represented by the border between Figure 2B,C).
A neuron consists of a cell body and its processes, an axon, and one or more dendrites.
