The atypical ribs include ribs 1, 2, 10, 11, and 12. Rib 1 is usually shorter and wider than all other ribs, and its broad, flat surface contains grooves that support the subclavian vessels. Because rib 1 articulates with first thoracic vertebra only, there is a single facet on its head (typical ribs have two facets, as mentioned above).
