There are various structures related to majja dhatu. These can be included in the system. The structures are as described below
===Channels of transportation and transformation of Majja dhatu (Majjavaha srotas)===
Layer of majja (Majjadhara Kala)
Kala is the layer in outer coverings of body observed in sagittal section.The layer of adipose tissue (Medodharakala)present inside the long bonesis known as majja.Though there are no direct references illustrating the layer of bone marrow(majjadharakala) in the classical texts,it can be observed as the thin layer of tissue called endosteum. This is the lining in the bone cavity that separates bone cells and bone marrow.

Types of bone marrow
There are two types of bone marrow viz. red bone marrow and yellow bone marrow.
There are various structures related to majja dhatu. These can be included in the system. The structures are as described below.
In yellow bone marrow, there is abundance of fat cells with less amount of blood forming tissue.In early childhood, red bone marrow is predominantly observed.In adult life, the fatty bone marrow retains the essential reticular structure of the haemopoietictissue.It is capable of turning into red bone marrow under suitable stimulus like starvation.
In red bone marrow, there are phagocytic endothelial cells. It is full of erythrocytes in different stages of formation and immensely vascular consisting of arteries, veins and rich plexus of sinusoids.
