Thoracic part of the ventral serrate muscle

About the thoracic part of the ventral serrate muscle of the dog

Thoracic part of the ventral serrate muscle is a muscle of the chest (thorax), on the left side. Its name in the Nomina Anatomica Veterinaria is Musculus serratus ventralis thoracis. Digitations interdigitate with the external abdominal oblique. You can turn it above, see it in place in the chest of the dog, 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

Transverse processes of cervical vertebrae three to seven, and the lateral faces of roughly ribs one to eight.

Insertion

Serrated face on the medial side of the scapula, near its dorsal border.

Action

Slings the trunk between the forelimbs, swings the scapula, and its thoracic slips can aid breathing.

Nerve

Ventral branches of the caudal cervical nerves and the long thoracic nerve.
