Description
Summary: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 demonstrate 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. KEY WORDS: Digital flexor muscles; Suspensory/stay apparatus; Thoracic limb; Lama glama. Fueron disecados e ilustrados los musculos flexores digitales del miembro toracico de cuatro llamas con la finalidad de aportar datos sobre el aparato suspensor (de apoyo) que soportan estas estructuras. Se realizo una extensa busqueda bibliografica dada la incompleta informacion existente de estas estructuras anatomicas. La popularidad de la llama en todo el mundo como uno de los animales domesticos utilizados ha aumentado en los ultimos aaos. Es importante describir detalladamente la anatomia de esta especie para su tratamiento en condiciones patologicas. La descripcion de las estructuras anatomicas y las ilustraciones originales demuestran peculariedades genuinas y diferencias entre la llama y los rumiantes domesticos. En llamas, las tres cabezas del musculo flexor profundo de los dedos se originan y se conectan entre ellas en una muy peculiar combinacion, con uno de los tendones recibiendo un fasciculo del musculo flexor ulnar del carpo. El musculo flexor superficial de los dedos tiene un tendon delgado el cual se fusiona con la fascia palmar y luego se amplia. No existen musculos interflexo
