Ganglion
Translation- Ganglion
In
anatomy , a ganglion "(pl. "ganglia")" is a tissue mass. [DorlandsDict|four/000043442|ganglion]Neurology
In neurological contexts, ganglia are composed mainly of somata and dendritic structures that often interconnect with other ganglia to form a complex system of ganglia known as a
plexus . Ganglia provide relay points and intermediary connections between different neurological structures in the body, such as the peripheral and central nervous systems.There are two major groups of ganglia:
* dorsal root ganglia (also known as the spinal ganglia) - contain the cell bodies of sensory (afferent)nerve s
* autonomic ganglia - contain the cell bodies of autonomic nerves.In the autonomic nervous system, fibers from the
central nervous system to the ganglia are known aspreganglionic fibers , while those from the ganglia to the effector organ are calledpostganglionic fibers .Basal ganglia
The term "ganglion" usually refers to the
peripheral nervous system . cite web |url=http://embryology.med.unsw.edu.au/Notes/Index/G.htm |title=UNSW Embryology- Glossary G |accessdate=2008-01-13 |format= |work=]However, in the brain (part of the
central nervous system ), the "basal ganglia " is a group of nuclei interconnected with thecerebral cortex ,thalamus andbrainstem , associated with a variety of functions: motor control, cognition, emotions and learning.Partly due to this ambiguity, the
Terminologia Anatomica recommends using the term "basal nuclei" instead of "basal ganglia".See also
