Book 8

Turning to the hand, the first part of the palm consists of many minute bones of which the number is uncertain, but all are oblong and triangular, and are connected together on some plan since the upper angle of one alternates with the base of another; therefore they appear like one bone which is slightly concave. Now two small bones project from the hand and are fitted into the hollow of the radius; and at the other end five straight bones directed towards the fingers complete the palm; from these spring the fingers themselves, each composed of three bones; and all are similarly formed. A lower bone is hollowed out at its top to admit a small protuberance from an upper bone, and sinews keep them in place; from them grow nails which become hard, and thus these adhere by their roots to flesh rather than to bone.

And such are the arrangements for the upper limbs. Now the bottom of the spine is fixed between the bone of the hips, which lies crosswise and is very strong and so protects the womb, bladder and rectum; and the bone bulges out externally, is bent up towards the spin, and on the sides that is, the hips proper, it has rounded hollows; and from these start the bone they call the comb, situated crosswise above the intestines below the pubes, and this supports the belly; in men the bone is straight, in women more curved outwards so as not to hinder parturition.
