Examples from the Web for haemal
The haemal spines of the turned-up tip of the tail are flattened (hypural bones) and serve to support the caudal fin rays.
The ventral arcualia become, in the tail region only, also incorporated in complete arches—the haemal arches.
Haemal arches similar to the neural arches are often found as in Urodela.
Both neural and haemal arches are ossified continuously with the centra.
Counts of 10 and 16 haemal arches were obtained in two of the specimens.
