The metapophysis is at its maximum in the fourth lumbar vertebra, but is large even in the last. The neural spine is longest at the fourth. The transverse process increases rapidly from the first lumbar vertebra to the fourth, and is slightly longer in the fifth and sixth lumbar vertebrae. The zygapophyses continue to be directed as in the fifth lumbar vertebra, except that the postzygapophyses of the seventh look once again more downwards. The centrum of the seventh lumbar vertebra is not longer than is that of the first, and the same is the case with the neural arch. § 8. Having noted the characters of the vertebrae next behind the dorsal ones, we may advance to those in front of them. Of the seven cervical vertebrjb the first two are sufficiently exceptional to demand separate notice. The other cervicals are very much alike, but the fifth may be selected for comparison with the fifth dorsal vertebra. Its centrum is relatively wider from side to side and narrower.
