As such, they are derived primarily from neural crest cells. During embryogenesis, the upper limb derives from the developing limb bud starting at approximately 26 days after fertilization. 6 Peripheral nerves are made of fibers called axons that are insulated by surrounding tissues. Peripheral nerves are fragile and easily damaged. A nerve injury can affect the brain's ability to communicate with muscles and organs. Damage to the peripheral nerves is called peripheral neuropathy. 7 somatiska nervsystemet 8 Det somatiska nervsystemet består dels av nerver som styr kroppens viljestyrda muskler, till exempel rörelser i armar och ben, de motoriska nerverna, dels av. 9 Conference of Peripheral and Maritime Regions Plexus brachialis betyder armens nervfläta och består av nerverna som styr muskelfunktion och känsel i axel, arm. 10
