A set of ribs is connected to Each and every entire body vertebra apart from a few promptly driving The pinnacle. By definition, there are no ribs around the tail vertebrae. Each individual vertebra articulates with its neighbour at five distinctive points: initially, within the Get hold of place concerning the main, central bodies on the bones (centra), which can be a ball-and-socket joint; then at two projections (prezygapophyses and postzygapophyses) from your centra, with articulating surfaces that lie earlier mentioned and underneath; And eventually the zygosphenes and zygantra, found Practically completely in snakes, the zygosphene getting a projecting shelf over the upper Component of the vertebra as well as zygantrum staying a pocket into which the zygosphene fits and within just which it can swivel.
