This study, performed through means of dissection process, looked at the origin and distribution of the suprascapular nerve in 30 zebu-crossed bovines fetuses. The pieces were fixed in aqueous 10% formaldehyde by different points of subcutaneous, intravenous, intramuscular or intracavitary injections, and soon afterwards it was made the immersion in containers with the same solution The suprascapularis nerve showed symmetry in relation to their origin in 30 animals (100%) and it originated in 56 antimeres (93.34%) of C6 and C7 (47.67% to right and 47.67% to left) in four antimeres (6.66%) of C6, C7 and C8 (3.33% to right and 3.33% to left) and gave branches to the supraspinatus muscle and infraspinatus in 100% of the cases . There was no significant difference between the frequency of the muscular branches assigned by that nerve to the right and left sides and also in relation to the sex of fetuses in this investigation.
