CONSTANTINESCU, Gheorghe Mircea; REED, Shannon Kelly  e  CONSTANTINESCU, Ileana Anghelina. The Suspensory Apparatus and Digital Flexor Muscles of the Llama (Lama glama) 1: The Thoracic Limb. Int. J. Morphol. [online]. 2008, vol.26, n.3, pp.543-550. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022008000300006.

The digital flexor muscles of the thoracic limb of four llamas were dissected and illustrated to provide data about the suspensory (support) apparatus and weight bearing structures. An extensive literature search was performed and yielded incomplete information about these anatomical structures. The popularity of the llama world wide as a domesticated animal used for show and fiber has increased in the recent years. It is helpful to describe the anatomy fully to aid in understanding of the species and treatment of pathologic conditions. The description of the anatomical structures and the original illustrations demónstrate genuine peculiarities and differences between the llama and domestic ruminants. In llamas, the three heads of the deep digital flexor muscle (DDF) originate and connect with each other in a very peculiar combination, with one tendon receiving an attachment from the flexor carpi ulnaris muscle (FCU). The superficial digital flexor muscle (SDF) has a thin tendon which is fused with the palmar fascia and then broadens. There are no interflexor muscles. Additionally, unexpected lumbricalis muscles are found in the distal limb and vary in number between the fore and hind limb. The anatomy of the suspensory apparatus in the thoracic limb is evaluated in this paper.
