The woolly-monkey (Lagothrix lagothricha) is an antropoid belonging to the Atelidae Family which includes the largest neotropical primates. A female cadaver woolly-monkey was fixed in a 10% formaldehyde solution and dissected using a stereoscopic magnifying glass and photodocumented. The brachial plexus originated from the spinal nerves C5 to C8 and T1, forming the cranial, medium, and caudal stems, from which derived the peripheral nerves; those nerves had similar origin and innervation area when compared to plexuses from other primates, with the exception of the musculocutaneous nerve that crossed the coracobraquial muscle. Data from studies with brachial plexus from primates allow the access to valuable information regarding the morphology of those animals, and could also assist in the establishment of anatomical parameters among species, which could then contribute to anesthetic procedures and injury treatments.
