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.

Fragment from the book Sutton JB. Ligaments: Their Nature and Morphology (1887). According to the author, the ligamentum capitis femoris (LCF) is a modified tendon of the pectineus muscle. This section of the chapter duplicates article 1883SuttonJB .   Quote pp. 38-41 THE LIGAMENTUM TERES. The round ligament of the hip joint has long been an anatomical puzzle, and many opinions have been held concerning its nature. It is, however, best regarded as the divorced tendon of a muscle, and here arguments will be raised in order to show that in all probability it belonged to the pectineus, but has become separated from it in consequence of skeletal modifications. The ligamentum teres is a structure fairly constant in Mammalia, but is wanting in the Seal, Elephant, Rhinoceros, Walrus, Ornithorhynchus, Echidna, Sea-otter, (Enhydra marina) (of this form I have had the good fortune to dissect the joints in two specimens), Sloth, Orang, Walrus, Hyrax, and Pangolin. The two last ment...

  According to the author, the ligamentum capitis femoris (LCF) is a tendon of the pectineus muscle, separated from it in consequence of skeletal modifications.   THE LIGAMENTUM TERES By J. B. SUTTON, Demonstrator of Anatomy, Middlesex Hospital. (PLATE VIII.) The round ligament of the coxo-femoral articulation has long been an anatomical puzzle, consequently many diverse notions exist concerning it. Some anatomists ascribe to this hollow band of fibrous tissue very important functions in the mechanism of the hip-joint; others deprive it of all glory, simply assigning to it the menial duty of conveying blood-vessels to the head of the femur. Certain authors content themselves with a brief description of its attachments; others give elaborate and detailed accounts, extending over several pages, of its anatomy and supposed function. My object in the present communication is to show that this singular ligament is nothing more than the tendon of the pectineus muscle, sepa...
