PLEXUS BRACHIALIS Meaning and
Definition
-
The plexus brachialis is a complex network of nerves located in the upper body, specifically the region of the shoulder and arm. Derived from Latin, the term "plexus brachialis" translates to "brachial plexus" in English. It is an intricate interweaving of nerve fibers arising from the spinal cord, specifically the lower cervical and upper thoracic region.
This network of nerves is responsible for innervating the muscles and providing sensory information to the upper limb. It delivers signals that control movement and sensation to the various muscles, joints, and skin of the shoulder, arm, forearm, and hand.
The plexus brachialis is composed of several major nerves, including the roots, trunks, divisions, cords, and branches. The five root nerves (C5-T1) merge and form the three trunks (upper, middle, and lower), which further divide into six divisions. These divisions unite to create three cords (lateral, medial, and posterior), and eventually branch out to supply specific areas of the upper limb.
Injury or trauma to the plexus brachialis can lead to conditions such as brachial plexus injuries or thoracic outlet syndrome. Symptoms of these conditions may include pain, weakness, numbness, or tingling in the affected arm or hand.
Given its vital role in the functioning of the upper limb, understanding the structure and function of the plexus brachialis is crucial for medical professionals in diagnosing and treating conditions related to this complex network of nerves.
