The drawing: Drawn for this site, 2026-09-20. Proportions and bone shapes were checked by eye against three public-domain pictures on Wikimedia Commons: Gray188.png (side view of the skull from Gray, Anatomy of the Human Body, 1918), Human_skeleton_front_-_no_labels.svg and Human_skeleton_back_en.svg (Mariana Ruiz Villarreal, released into the public domain), and against the descriptions of the wrist and ankle bones in the English Wikipedia articles Carpal bones and Tarsus (skeleton). Nothing was traced or copied, and the numbers and labels are our own. Licence: own work

The skeleton is drawn from the front and the back, with the skull, one hand and one foot larger. The names run from l'osso frontale to le falangi del piede, each with il, lo, la, l' or le.

Which article each bone takes
Twenty-two of the 35 names are masculine and thirteen feminine: la mascella, la mandibola, the three kinds of vertebre, le costole, la clavicola, la scapola, l'ulna, la rotula, la tibia and both sets of falangi. Lo stands before s plus a consonant, as in lo sterno, and l' before a vowel: l'omero, l'ilio, l'ischio, l'astragalo.
One noun for a group of bones
Il carpo, il metacarpo, il tarso and il metatarso each name a group of bones, not one bone. The bones of the wrist together are le ossa del carpo.
L'ilio is also written l'ileo, the same word as the ileum of the intestine.

Lo scheletro, a masculine noun. A bone is l'osso, the skull is il cranio and the spine is la colonna vertebrale.
What is the plural of osso in Italian?
Le ossa, a feminine plural, for the bones of a body. The regular masculine plural, gli ossi, also exists; WordReference marks le ossa as the more common of the two.
