Clinical InformationClinical

  • Brachial Plexus

    the large network of nerve fibers which distributes the innervation of the upper extremity. the brachial plexus extends from the neck into the axilla. in humans, the nerves of the plexus usually originate from the lower cervical and the first thoracic spinal cord segments (c5-c8 and t1), but variations are not uncommon.

  • Brachial Plexus Block

    a blocking of neural conduction in the network of nerve fibers innervating the upper extremity.

  • Brachial Plexus Neuritis

    a syndrome associated with inflammation of the brachial plexus. clinical features include severe pain in the shoulder region which may be accompanied by muscle weakness and loss of sensation in the upper extremity. this condition may be associated with virus diseases; immunization; surgery; heroin use (see heroin dependence); and other conditions. the term brachial neuralgia generally refers to pain associated with brachial plexus injury. (from adams et al., principles of neurology, 6th ed, pp1355-6)

  • Brachial Plexus Neuropathies

    diseases of the cervical (and first thoracic) roots, nerve trunks, cords, and peripheral nerve components of the brachial plexus. clinical manifestations include regional pain, paresthesia; muscle weakness, and decreased sensation (hypesthesia) in the upper extremity. these disorders may be associated with trauma (including birth injuries); thoracic outlet syndrome; neoplasms; neuritis; radiotherapy; and other conditions. (from adams et al., principles of neurology, 6th ed, pp1351-2)

Patient EducationClinical

Cancer

Cancer is not just one disease but many diseases. Cancer begins in your cells, which are the building blocks of your body. Usually, your body forms new cells as needed, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should.
