Where is the origin of the brachial plexus located?

The origin of the brachial plexus is located in the middle of the neck, specifically from the lower cervical and upper thoracic spinal nerves (C5-T1). This important neural network innervates the upper limb, providing motor and sensory functions. Understanding the anatomical position is crucial for defensive tactics training, as it allows practitioners to apply techniques that may involve targeting areas of the body related to nerve bundles for effective control or self-defense. The other locations noted—lower back, elbow area, and upper thigh—do not correspond with the brachial plexus, emphasizing the significance of recognizing anatomical structures in defensive strategies.
