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.
Note from author: In some species (mainly in carnivores), the ventral serrate muscle of the neck (serratus ventralis cervicis) and the ventral serrate muscle of the thorax (serratus ventralis thoracis) are continuous together, and described together. We think it's not a convenient way because:
