Study Notes
Conical and Brachial Plexus
- Conical and brachial plexuses are complex networks of nerves.
- These networks are formed by the ventral rami of spinal nerves.
- The nerves in these plexuses innervate various parts of the body.
- Specific nerves originate from the brachial plexus, crucial for upper limb movement and sensation.
