The brachial plexus is a network of nerves fibers that connects the arm to the spinal cord. Injury of it could cause the arm to be paralyzed, a lack of muscle control, and/or a lack of sensation.
The cervical spinal nerves form the cervical plexus, the brachial spinal nerves form the brachial plexus, the lumbar and sacral spinal nerves form the lumbosacral plexus, and the sacral spinal nerves form the sacral plexus.
The nerve that control the larynx during breathing is the Vagus Nerve.
The major nerve that serves the head, neck, and shoulder plexus is the spinal accessory nerve (CN XI). It originates in the brainstem and courses through the neck to innervate muscles involved in head turning and shoulder shrugging.
The phrenic nerve arises from the cervical plexus (C3-C5) and supplies the diaphragm, which is the primary muscle involved in breathing.
Cervical: C1 - C5Innervates muscles of neck and extend into thoracic cavity, where they control diaphragmatic muscles. Major nerve: Phrenic...which provides entire nerve supply to diaphragm.Brachial: C5-T1Innervates pectoral girdle and upper limbs. Major nerves: Radial nerve, median nerve, ulnar nerve.Lumbar: T12 - L4Innervates pelvic girdle and lower limbs. Major nerves: Genitofemoral nerve, lateral femoral cutaneous nerve, and femoral nerve.Sacral: L4-S5Innervates pelvic girdle and lower limbs. Major nerves: Sciatic nerve (which branches into tibial and fibular nerves) and pudendal nerve.
Cervical plexus....
The cervical spinal nerves form the cervical plexus, the brachial spinal nerves form the brachial plexus, the lumbar and sacral spinal nerves form the lumbosacral plexus, and the sacral spinal nerves form the sacral plexus.
The major plexuses of the spinal cord are the cervical plexus (C1-C5), brachial plexus (C5-T1), lumbar plexus (L1-L4), and sacral plexus (L4-S4). These plexuses are networks of nerves that supply motor and sensory function to various regions of the body.
The phrenic nerve plexus supplies the diaphragm and controls its movement during respiration. Damage to this plexus can lead to impaired breathing and respiratory function.

The Phrenic Nerve
The major nerve that serves the head, neck, and shoulder plexus is the spinal accessory nerve (CN XI). It originates in the brainstem and courses through the neck to innervate muscles involved in head turning and shoulder shrugging.
The brachial plexus is a network of nerves that originate from the lower cervical and upper thoracic spinal cord. It controls the muscles of the shoulder, arm, and hand, and provides feeling to the upper limb. Damage to the brachial plexus can result in weakness or loss of function in the affected areas.
