Semispinalis Capitis (Arnold)

The slips of attachment vary considerably in number. The muscle may receive accessory slips from longissimus or spinalis (dorsi s. thoracis). A rare variation is the presence of a second lamella under the medial portion of the muscle, extending from one or more of the upper thoracic transverse processes to the occipital bone.

Another slip of muscle, biventer cervicis (Henle), is superficial and located medially, may appear to have a tendinous intersection, but remains fleshy; it may have two distinct bellies, or two distinct bellies joined only by a strong tendon (several centimeters in length). It arises from lower cervical and upper thoracic vertebrae and transverse processes, and inserts onto the occipital bone and inion.

Syn.: m. complexus (Cowper), complexus major (Krause), Grand complexus (Cruveilhier)
