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.
1 Ganglia-groups of neuron cell bodies that lie peripheral to the central nervous system in vertebrates. 2  Bipolar neurons-cell body located near the middle of the axon; characteristic of retinal neurons. 3  Unipolar neurons-cell body lies off to one side of axon; characteristic of sensory neurons. Oligodendrocytes-neuroglial cells of ectodermal origin that myelinate axons in the central nervous system and forms the white matter of the central nervous system (unmyelinated axons are grey matter. 2  Astrocytes-star-shaped nutritive and supportive glia cells of the central nervous system.
