    Ninja Nerds!
    In this lecture Professor Zach Murphy will be discussing nerve injury along with wallerian degeneration and regeneration. During this lecture we begin by lecturing on the normal anatomy of a nerve including the epineurium, perineurium, and endoneurium. Next, we will review the Seddon classification of nerve injury including Neurapraxia, Axonotmesis, and Neurotmesis. Finally, we conclude with the process of wallerian degeneration including proximal and distal segment changes along with the regeneration physiology. We hope you enjoy this lecture and be sure to support us below!

    Recently had a lumbar laminectomy which was to treat my radiculopathy in addition to relieving the pressure on the spinal chord. I am living through significant motor loss in the tibialis, calf muscles, quadriceps, glute Maximus and medius. Prior to and right after surgery I walked with a significant Trendelenberg gate. So far that has cleared up. Since my tibialis and calves still do not work, your video struck many chords with me. Thanks and kudos for an informative, well organized and pleasantly presented video. My fingers are still crossed, but my hopes are up.

    Thanks for the detailed explanation. I've recently had surgery to remove a Schanomma located at the intercostal nerve (Between T1/T2, about two inches from the left of the spine). It was VATs so was minimally invasive, but there has been some nerve compression around the area they entered from and also from the location of the removal site. This video really helped me understand the regeneration and recovery process. Keep up the good work.

Bone is now back in place but I have zero use of my hand due to the nerve damage. I now understand my injury better & have new found hope for recovery. 🌷🌷🌷

      Omg! I just saw this after my grown son has had severe neurological problems for years. He’s had all these symptoms of nerve damage and had meningitis at 7 and 7 years ago had a severe fall onto cement and a closed head injury that took a year to heal. Why didn’t anyone check his neck??? I finally got him an x-ray on his neck and lower back and the nerves on the left side are completely blocked off. I’m trying to find a way to help him! Thank you! Thank you!

Seem like my primary doctor is running from liability by not referring me to someone that can help. The main thing i'm finding out is to increase circulation by unclogging arteries. research foods to unclog arteries. B-complex mainly choline and inositol, cq10, omega 3, anti-inflammatory foods, research low impact exercise depending on injury.
