Overview of the Cervical Plexus
Cervical plexus is the junction of tiny network of nerve fibers that transport sensory information to head, shoulder and neck. This continues till the pharynx and encloses within the neck. It even extends up to the pharynx. No doubt, it is an important part for the PNS or the peripheral nervous system, that’s a part of the CNS or Central Nervous System located outside the brain and spinal cord.
A superficial plexus nerve gives sensory information to the ear, neck and clavicle. Apart from these, all the nerves also arise from the lateral periphery, interestingly; you don’t have access to view the node. So, to find out this nerve, researchers take the help of interscalene groove. There are three main branches of the cervical plexus nerve. These include the cutaneous branches that are located at the center of sternocleidomastoid and placed in superficial fascia in the neck. The next branch is the muscular branch that travel deeply within plexus as well as provide sternocleidomastoid, trapezius as well as suboccipital muscles. The last branch includes the communicating branches that are provided to the plexus by the SNS or sympathetic nervous system.
This plexus block is really effective and produces anesthesia over the shoulders, neck and pectoral region. While injecting the solution it must be noted that intravascular injection isn’t used. These injections tend to block the nerve resulting is serious issues like Horner’s syndrome.
Now, this cervical plexus nerve is prone to injuries caused by sports, accidents and hard labor. During such injuries, the nerves get overstretches or compressed and this leads to unbearable pain. Apart from this, injuries also lead to numbness along the neck and shoulder areas along with weakness. The wounds are also very difficult to manage and can only be treated with traction. This nerve is also vulnerable to motorcycle injuries and treatment might be a little difficult. Alongside tractions some of the other therapies used in plexus injury include stretches, flexion and isometric exercises.
