1The brachial plexus:
- AIt represents a peripheral component of the autonomic nervous system
- BIt is formed by the anterior branches of the C8 – T1-3 nerves
- CThe anterior branches of the aforementioned nerves form three trunks – superior, medial and
lateral, localized in the interscalene space - DIt has the supra- and infraclavicular parts
- EIt gives off the supraclavicular (cutaneous) nerves
2 Branches of the brachial plexus are grouped in:
