Book One -- The things that sustain and support the entire body, and what braces and attaches them all. [the bones and the ligaments that interconnect them] | Chapter 28 On the Ossicles Which Resemble a Sesame Seed

[Introduction]

This chapter is illustrated in particular by the first figure at the beginning of chapter 25, showing the inner [palmar] surface of the hand together with the ossicles [ossa sesamoidea] to be described in this chapter, near the letters N, T, V, V, X, and Y, 1 of which N and T are also seen in the second figure of the chapter. Likewise, the second figure to be placed at the head of the thirty-third chapter serves the same purpose next to the letters m (which is also seen in the first figure), y, w, and *. Also, the figures illustrating the entire structure of bones shows these ossicles marked k. 2


The two ossicles located beneath the first internode in the big toe and marked w and y in the illustration just mentioned are drawn separately in this small diagram. A here identifies the lower surface of the inner bone [y], the one that presses on the ground, B the upper surface of the same bone, which faces the head of the metatarsal bone supporting the toe, C the lower surface of the outer and lesser bone [w], D the upper. 3

Professors of anatomy have mentioned certain ossicles (these will be seen in the figures that I have included at the beginning of the chapter) which some say fill out the joints, tighten them, and strengthen them to make them less prone to dislocation. But I know no one to have written in which joints they are located or where they are found.
