the upper two or three thoracic vertebrae. It extends upwards, and slightly 

 laterally, and ends in two tendinous slips which are inserted into the anterior 

 tubercles of the transverse processes of the fifth and sixth cervical vertebne. 

 In the interval between this portion of the longus colli and the scalenus 

 anterior, the vertebral artery will be seen. The upper oblique part arises by

three tendinous slips from the anterior tubercles of the transverse processes 

 of the third, fourth, and fifth cervical vertebrae ; it tapers somewhat as it 

 proceeds upwards and medially to obtain a pointed and tendinous insertion 

 into the anterior tubercle of the atlas. The vertical part of the muscle is 

 much the largest of the three divisions. It lies along the medial side of the 

 oblique portions, and is intimately connected with both of them. It arises 

 in common with the inferior oblique part by two or three slips from the 

 sides of the bodies of the upper two or three thoracic vertebne ; above
