ABSTRACT:
The common marmoset (Callithrix jacchus) is a small primate that inhabits shrub forests of the Caatinga and the Atlantic Forest in Brazilian Northeast. This species of marmoset is very common and easy to adaptation in captivity, aspect that encourages illegal capture of these animals that are victims of mistreatments, causing injuries. The lack of knowledge in anatomy in marmosets and other wildlife hinders the safe application of clinical, surgical and therapeutic procedures. The brachial plexus has been described in some species of animals, but so far, there is no description for common marmoset (Callithrix jacchus). To study the brachial plexus of these animals were dissected ten corpses of common marmosets (Callithrix jacchus) adults, being five males and five females. In all animals, the brachial plexus was originated from spinal nerves C5, C6, C7, C8 and T1, with few variations in origin and the contributions of the nerves in both antimeres, forming three trunks: the cranial (C5 and C6), medium (C7) and caudal (C8 and T1).
