Definition
The cervical part of the trapezius muscle in animals is located on the dorsal region of the neck, more specifically on the median fibrous raphe of the neck, which is an area where the muscle fibers converge. It extends from the first cervical vertebra to the third cervical vertebra. This portion of the muscle is generally wider and flatter, forming an elongated triangle.
Origin: Median fibrous raphe of the neck in carnivores and domestic pigs; nuchal ligament in ruminants and equids.
Insertion: Spine of the scapula.
Action: Elevation of the forelimb and facilitates the forward movement of the limb (protraction).
Nerve: Accessory nerve.
