The lamiuas of the cervical ligament are in relation, outwardly, with the superior branch of the ilio-spinal ligament, the transverse sjiiuous muscle of the neck, and the great complcxus. (This important structure, which is in reality the mechanical stay and support of the heavy head and neck of quadrupeds, and is usually termed the ligamentum nuchce, is all but abseut in Man, being represented in him by a thin narrow band, or rather two thin planes of fibres, the ligamenta suhflava. It is described by Leyh as if there were not two portions, and that excellent anatomist does not appear to insist sufficiently on the difierence between the dorso-nuchal and the dorso-lumbar divisions. Percivall, who almost entirely neglects the ligaments, also makes no distinction. The dilference in structure, elasticity, and situation, warrants the distinction made by Chauveau. As already indicated, the function of this ligament, and more particularly of its nuchal division, is to maintain the head and neck in their natural position dm-ing repose, and to allow the most extensive movements at other times.) b. Interspinous ligaments (Fig. 80, 3).—Fibrous laminfe fill the inter- spinous spaces, and are attached, before and behind, to the opposite borders of the spinous processes which they unite ; they are continued below by the interlamellar liga- ments, forming two lateral planes which are applied against each other, like the laminae of the cervical ligament, and covered outwardly by the transverse spinous (dorsalis colli) mixscle. In the region of the neck, the interspinous ligaments are yellow and elastic. In the dorso- l
