The omotransverse muscle (Musculus omotransversarius) is a strong cord-like muscle between the wing of the atlas, the transverse process of the axis and the fascia covering the lateral aspect of the shoulder joint and the spine of the scapula. Its ventral border is fused to the cervical part of the trapezius muscle and in the horse, it unites with the cleidomastoid muscle.

Origin: Distal portion of the scapular spine, as far as the acromion, and from that part of the omobrachial fascia that covers the acromial part of the deltoidius.

Insertion: Caudal end of the wing of the atlas and the transverse process of the axis 

Action: To draw the limb forward.

Nerve: Accessorius.

Note: this muscle is not present in human and not listed in the human Terminologia Anatomica, but for Barone, in some cases, it may be described in human as a surnumerar muscle termed "cleidotransverse muscle (musculus cleidotransversarius)".
