Abstract

Subepiphysal Bone Growth. —Two processes must be noticed in this connection.

1st, The replacement of the neck of the cartilaginous head or epipliysis by cancellous tissue as an accompaniment to the rise of the epiphysis caused by the growth of the cartilage forming its neck.

The cartilage is channelled by the advancing marrow, the rows of cartilage capsules being opened up.

The opening up of the rows of cartilage capsules results from the presence of a capillary blood-vessel forming the head of the column of marrow which lies in immediate contact with the next unopened capsule (Ranvier). The close proximity into which the pabulum is thus brought with the cartilage corpuscle in the unopened capsule nearest it causes it to grow rapidly and absorb the surrounding cartilage, this occurring, quickest in the direction of least resistance that is, towards the marrow.
