Robert Bruce calls these energy storage centres in his book Energy Work and he describes the principle three on the body.

Taoists call the wicks or channels that move through these spheroid energy storage centres; tan tiens.
Alchemists call the energy storage centres; stones.

I choose to use that alchemist term stones to distinguish the chakras from them.
Basically the Tree of Life has
7 grapefruit sized spheroid subtle energy centres on the spinal column
4 belly or head sized large energy storage centres
There are two chakras vertically stacked in the centre of each energy storage centre or stone
