In fact, while with the majority of mammals the equilibrium of the head is assured by very powerful cervical ligaments, and with anthropoid apes by very strong muscles, extending from the occiput to the spinous processes of the cervical vertebræ, twice as long as those of man (Figs. 1 and 2, a), which prevent the massive muzzle from falling upon the chest and pressing on the organs of respiration,[13] we see nothing of a similar kind in the genus Homo—no cervical ligament, and no powerful muscles at the nape of the neck. The very voluminous brain-case of man suffices to counterbalance the weight of the much reduced maxillary part, almost without the aid of muscles or special ligaments, and the head balances itself on the vertebral column (Fig. 2).
