Home : Technical Terms : CAD Definition. CAD. Stands for Computer-Aided Design.. CAD is the use of computers to create 2D and 3D designs. Common types of CAD include two-dimensional layout design and three-dimensional modeling. 2D CAD has many applications, but it is commonly used to design vector-based layouts.
In anatomy, a ganglion (/ËÉ¡Ã¦ÅÉ¡liÉn/ GANG-glee-Én; plural ganglia) is a nerve cell cluster or a group of nerve cell bodies located in the autonomic nervous system and sensory system. Ganglia house the cell bodies of afferent nerves.
A couple of useful terms to define at this point are nucleus and ganglion. In the central nervous system, a collection of neuron cell bodies is called a nucleus. In the peripheral nervous system, a collection of neuron cell bodies is called a ganglion (plural: ganglia). The one exception to this rule that you may have encountered is the basal ganglia in the brain.
