The function of the epiphysis is the growth of bones. It also helps in the transmission of weight from areas under great pressure and force, and it relieves the weight of the bone owing to the porous nature of the enlarged part.
The epiphysis is a growth area found at the joints near the end of the long bones. It is made from red bone marrow, which is the main producer of red blood cells.
The epiphysis is classified into four types: the pressure epiphysis that is involved in the formation of joints, the traction epiphysis that facilitates the attachment for supporting tendons and ligaments, the atavistic epiphysis that are fused bones and the aberrant epiphysis that differs slightly in structure from the others.
