1884SuttonJB

 

Fragments from the article Sutton JB. Ligaments: Their Nature and Morphology (1884). The author discovered that in the ostrich the ligamentum capitis femoris (LCF) was not continuous with the ambiens muscle, but with a muscular slip which ran parallel with the-muscle, and ended in the adductor mass. This publication develops the theme of article 1883SuttonJB.

I must now pass on to consider certain ligaments of the appendicular skeleton, commencing with some additional remarks on the ligamentum teres.

The Journal of Anatomy and Physiology, vol. xvii January 1883, contains a short article on the ligamentum teres, in which I have endeavoured to point out that many ligaments are the tender of muscles which were originally in relation with the joint; but the parent muscle has either formed new attachments or become obsolete, whilst the tendon remains as a passive element in the articulation. In addition to the ligamentum teres the following structures must be placed in that category viz.: - the internal and external lateral ligaments of the knee-joints, the long and short plantar ligaments, and the interosseous membrane of the fore-arm and leg.

Since writing the article on the ligamentum teres, I have had an opportunity of dissecting a very young ostrich, in which the continuity of muscle and tendon does not admit of the slightest doubt (fig. 3). But the arrangement of the muscles differed somewhat from the condition found in the alder bird. The ligament itself was not continuous with the ambiens, but with a muscular slip which ran parallel with the-muscle, and ended in the adductor mass (fig. 3). This may possibly represent the inner slip of the pectineus of mammals, and is to be regarded as an anomaly inasmuch as it was separate from the ambiens muscle.
