Dendritic agate is prized in Russia as a stone of longevity, good health and prosperity. Like other types of chalcedony, dendritic agate has a hardness of 6.5 to 7 on the Mohs scale, a specific gravity of 2.59 to 2.67 and a refractive index of 1.530 to 1.540.

Dendrites are one of two types of protoplasmic protrusions that extrude from the cell body of a neuron, the other type being an axon. Axons can be distinguished from dendrites by several features including shape, length, and function.

These signals will accumulate in the cell body, or soma, of the neuron after being received by the dendrites. Once action potentials are received by the dendrites, they will be sent to a portion of the soma known as the axon hillock, neck region of the cell body.

Dendrites are the segments of the neuron that receive stimulation in order for the cell to become active. They conduct electrical messages to the neuron cell body for the cell to function. This lesson discusses dendrites, their function, and their importance in neuron activity.

Dendrites (from Greek δένδρον déndron, tree), also dendrons, are the branched projections of a neuron that act to propagate the electrochemical stimulation received from other neural cells to the cell body, or soma, of the neuron from which the dendrites project.

Aside from a beautiful dendritic solidification pattern, this video also shows ‘competitive growth’, where dendrites growing in directions less favorably oriented to the heat flow are impinged by more favorably oriented dendrites (the winners!).

About Dendritic Agate. Dendritic agate is a whitish-gray or colorless chalcedony with tree- or fern-like markings known as dendrites. The varietal name agate is used for this gem even though it does not exhibit the banding that is typical of agate.

Dendrites are the structures on the neuron that receive electrical messages. These messages come in two basic forms: excitatory and inhibitory. Excitatory action potentials increase the stimulation of a neuron, while inhibitory action potentials decrease the activity of the neuron.

What are Dendrites? By Morgan Gallagher on Saturday, January 29th, 2011 Have you ever heard a Metallurgist or a Welding Engineer talk about a dendritic structure, or secondary dendrite arm spacing, and wondered what those terms meant? When metals solidify, the solid/liquid interface in most cases is not planar; rather ‘fingers’ of solid jut forward ahead of the solidifying interface. These fingers are dendrites, which in turn become the subgrain structure in the solidified metal. The term dendrite is derived from the Greek word dendron, meaning ‘tree’. It is easy to see how this term is appropriate in the SEM image below (“Welding: Solidification and Microstructure” by David, Babu, and Vitek (JOM 6/03)), where the dendrites of a Ni-based superalloy, growing towards the viewer, resemble the birds eye view of a pine forest.

Due to its dendritic inclusions, dendritic agate bears some similarities to moss opal. However, dendritic agate is not referred to as 'moss agate'. In fact, there is another gemstone called moss agate, which has inclusions of green hornblende in moss-like patterns. Dendritic agate deposits are found in Brazil, India, Madagascar, the USA, Mexico and Kazakhstan.
