Short Neck Muscles The following three muscles are located on the back of the neck, just behind the skull: the obliquus capitis caudalis, the obliquus capitis cranialis, and the rectus capitis dorsalis major. They are covered by narrow and wide tendons and thin muscles, yet they help create the fullness on the back of the neck, determined in large part by the width of the atlas (the first neck vertebra) and the vertical projection of the axis (the second neck vertebra). Obliquus capitis caudalis (Large oblique muscle, Axoido-atloideus) • Origin: Entire side of the expanded upright spine of the. | Ç2 INDIVIDUAL MUSCLES NECK OBLIQUUS CAPITIS CRANIALIS WING OF ATLAS WING OF ATLAS HORSE TOP VIEW NUCHAL LIGAMENT OBLIQUUS CAPITIS CAU DALIS OBLIQUUS CAPITIS CRANIALIS OBLIQUUS CAPITIS CRANIALIS RECTUS CAPITIS DORSALIS MAJOR OBLIQUUS CAPITIS CAUDALIS NUCHAL LIGAMENT RECTUS CAPITIS DORSALIS MAJOR NUCHAL LIGAMENT DOG TOP VIEW OBLIQUUS CAPITIS CRANIALIS DOG RECTUS CAPITIS DORSALIS MAJOR WING OF ATLAS HORSE RECTUS CAPITIS DORSALIS MAJOR OBLIQUUS CAPITIS CAUOALIS Short Neck Muscles The following three muscles are located on the back of the neck just behind the skull the obliquus capitis caudalis the obliquus capitis cra-nialis and the rectus capitis dorsalis major.

Obliquus capitis caudalis Large oblique muscle Axoido-atloideus Origin Entire side of the expanded upright spine of the second neck vertebra axis . Insertion Rear surface of the expanded side projection or wing of the first neck vertebra atlas . Action Rotates the first neck vertebra which pivots on the second neck vertebra to the side thereby turning the head to the side. Structure Largest of the group this thick muscle is directed forward and outward. Its rear portion is buried in muscle but as it advances it approaches the surface. Obliquus capitis cranialis Small oblique muscle Atloido-occipitalis Origin Front surface of the wing of the first neck vertebra atlas . Insertion Rear part of the skull. Action Both sides together extend the head. Structure This is a short muscle which fill the space between the skull and the first neck vertebra. It is directed forward upward and inward. Rectus capitis dorsalis major Posterior straight muscle Axoido-occipitalis Origin Upper edge of the upright spine of the second neck vertebra. Insertion Rear end of the .
