Raphe

They are inserted into the midline raphae or the anococcygeal raphae and the coccyx.

It shows three symmetrical raphes (asterisk) radiating from the centre of the aortic root, but in fetuses there is often asymmetry between the raphes with the one between the left and noncoronary sinuses being larger than the others (red asterisk in Figure 2.14b).

The vast majority of the raphes do not bifurcate (123 genera), but the raphes of 7 genera do.

The invariant occurrence of adhesive EPS at both the driving and the non-driving raphes supports a model for constitutive, rather than induced, secretion of the raphe adhesive.
