Origin and distribution of the thoracodorsal nerve in pig fetuses of the lineage Pen Ar Lan

Considering the importance of the nerves that make up the brachial plexus, the aim was to study the origin and distribution of the thoracodorsal nerve. Thus, 30 pig fetuses from the lineage Pen Ar Lan obtained from natural abortions in breedings of the Triangulo Mineiro region were used. The specime...

description Considering the importance of the nerves that make up the brachial plexus, the aim was to study the origin and distribution of the thoracodorsal nerve. Thus, 30 pig fetuses from the lineage Pen Ar Lan obtained from natural abortions in breedings of the Triangulo Mineiro region were used. The specimens were prepared through the injection of 50% Neoprene Latex “450” and 10% formaldehyde solutions in the descending aorta artery, and immersion in the same solution for least 48 hours. The dissections were carried out bilaterally until reaching the brachial plexus, that emerged from the spinal ventral branches of the sixth (C6), seventh (C7) and eighth (C8) cervical nerves and from the first thoracic (T1). It was found that the thoracodorsal nerve was formed from C8 in two antimeres (3.33%); fromT1 in 17 antimeres (28.33%); and from C8 and T1 in 41 antimeres (68.33) and that there was symmetry with regard to its origin in 23 animals (76.66%). It was also found that the thoracodorsal nerve sent branches in 100% of cases for the latissimus dorsi muscle, and 36.66% for the teres major.
