About the diaphragm of the horse
Diaphragm is a muscle of the body (trunk), a single structure on the midline. Its name in the Nomina Anatomica Veterinaria is Diaphragma. You can turn it above, see it in place in the body of the horse, and open it inside the whole animal in Vetomica.
Where it runs from and to
A muscle is told apart from its neighbours by what it takes hold of at each end, which is also what decides what it does when it shortens.
- Origin
- The lumbar vertebrae by a right and a left crus, the inner surfaces of the caudal ribs and costal cartilages, and the xiphoid cartilage.
- Insertion
- Its own central tendon, which is pierced by the caudal vena cava.
- Action
- The chief muscle of breathing in; as it contracts and flattens the chest enlarges.
- Nerve
- Phrenic nerve, from the fifth to seventh cervical nerves.
Written for Vetomica in its own words from the standard reference anatomy of the horse; the books it was checked against are listed below.

Vetomica opens on this structure with every layer of the horse around it: peel back the skin and the muscles, cut a section through it, X-ray it, and practise naming it until you stop getting it wrong.
