The brachial plexus is a nerve plexus, or put simply an intricate network of different structures, such as blood
vessels or nerves. The brachial plexus is made up of nerves emerging from the spinal cord
, or to be precise, the C5 to D1 nerves, that is to say the nerves located at the three last cervical vertebrae
and the first thoracic vertebra
. The brachial plexus primarily serves to innervate the arm
, with almost all the motor nerves enabling muscle
contraction, and sensory nerves allowing us to feel in our arms
and forearms, originating in this plexus. If the brachial plexus is damaged, motor disorders, pain
, and sensory impairment can manifest in the areas innervated by these nerves.
