It is a large, thick muscle extends from the level of the second cervical vertebra to the fifth rib. The posterior part of this muscle is overlapped by the two anterior digitations of the succeeding. It lies partly on the neck and partly on the lateral wall of the thorax. Origin: From the transverse process of the second or third cervical vertebra to seventh cervical vertebra and the lateral face of ribs from first to the fifth rib.
Insertion: The triangular rough area at the dorso-anterior part of the ventral surface of the scapula. Action: To pull the scapula towards the neck. Two side muscles acting together to extend the neck and singly inclines the neck to its own side. Blood supply: Superior cervical, dorsal and vertebral arteries. Nerve supply: Fourth, fifth and sixth cervical spinal nerves and long thoracic nerve. Origin: External surfaces of ribs from 4 th to the 9 th.
Insertion: The rough line at the dorso-posterior part of the ventral surface of the scapula. See the picture at the top. Action: The two muscles act together as a sling to suspend the trunk between the two forelimbs. Acting singly it pulls the scapula upwards and backwards. When the limb is fixed, each side muscle acts as an extra-ordinary muscle of inspiration in respiratory exertions.

Description The ventral serrate muscle of the neck is a serrated, fan-shaped muscle extending from transverse processes of caudal cervical vertebrae to the facies serrata of the scapula.
Origin: Facies serrata of the scapula. Insertion: Transverse processes of the last five cervical vertebrae Action: Support of the trunk, to carry the trunk forward and backward; to carry the shoulder forward and backward with respect to the limb. Nerve: Ventral branches of cervical nerves. We think it's not a convenient way because: The ventral and dorsal serrate muscles are well separated by the dorsal scalene muscle.
In human, the homologous muscles are two different muscles: the ventral serrate muscle of the neck is the levator of scapula and the ventral serrate muscle of the thorax is the serratus anterior muscle The hierarchy taxonomy parents , is not the same in the Vth NAV muscles of the neck or muscle of the thorax.
