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.
The principal host for diamonds are rocks formed in the earth's mantle that are known as eclogite and peridotite that are carried to the earth's surface in magmas known as kimberlit e and lamproite.
Space Diamonds / Carbonado. Diamonds can be found all over the earth however, concentrations of these carbon crystals can form in placer oriented locations (sand and gravel benches) Gold will naturally concentrate in the lowest location in a stream bed, diamonds might. With a specific gravity of 3.5, diamonds are only slightly heavier than rock. If an area is prone to seasonal or flash floods, the most likely location to find diamonds are in the lighter gravels or leading compacted clay benches. Oxbow lakes are another excellent place where concentrations of diamonds can be found.
