Midbrain, Simplified Sections Of Internal Structure

Midbrain, Simplified Sections Of Internal Structure

This video is part of a playlist of videos on the internal structure of the brain stem. In this video, internal structure at the following section levels is described: - Level of inferior colliculus - Level of superior colliculus - Level of lower pons - Level of open medulla - Spinal cord For each fiber tract the location, function, origin and destination are summarized. Each nucleus is identified in terms of location, function and connections. Thus the session correlates anatomical structures seen in the midbrain with those of the pons, medulla oblongata and spinal cord. For this purpose a section of the spinal cord has also been added. After completion of this video session, it is expected that you will be able to develop a three dimensional picture of the gross anatomy of the medulla oblongata and its internal structure. Locate the positions of cranial nerve nuclei and the paths taken by the major ascending and descending nerve tracts. Assess the signs and symptoms presented by the patient and identify the exact location of a lesion affecting the brain stem. Correlate the signs and symptoms of vascular syndromes (Weber's and Benedikt's syndrome) with the nuclei and nerve tracts involved by the vascular lesions. Explain the dissociation of pupillary light reflex from accommodation reflex in central nervous system syphilis (Argyll-Robertson pupil) Presented and edited by Dr. Akram Jaffar, Ph.D.

Partial Knee Replacement

Partial Knee Replacement

Dr. Richard Cunningham, M.D. of Vail Summit Orthopaedics explains and performs Partial Knee Replacement. Unicompartmental knee replacement is an option for a small percentage of patients with osteoarthritis of the knee. Your doctor may recommend partial knee replacement if your arthritis is confined to a single part (compartment) of your knee. Your knee is divided into three major compartments: The medial compartment (the inside part of the knee), the lateral compartment (the outside part), and the patellofemoral compartment (the front of the knee between the kneecap and thighbone). In a unicompartmental knee replacement, only the damaged compartment is replaced with metal and plastic. The healthy cartilage and bone in the rest of the knee is left alone.

Pons, Simplified Sections Of Internal Structure

Pons, Simplified Sections Of Internal Structure

This video is part of a playlist of videos on the internal structure of the brain stem. In this video, internal structure at the following section levels is described: - Level of facial and abducent nucleus (lower pons) - Level of trigeminal nuclei (upper pons) - Level of open part of the medulla oblongata - Spinal cord For each fiber tract the location, function, origin and destination are summarized. Each nucleus is identified in terms of location, function and connections. Thus the session correlates anatomical structures seen in the pons with those of the medulla oblongata, midbrain and spinal cord. For this purpose, sections of the spinal cord, and medulla oblongata have also been added. After completion of this video session, it is expected that you will be able to develop a three dimensional picture of the gross anatomy of the medulla oblongata and its internal structure. Locate the positions of cranial nerve nuclei and the paths taken by the major ascending and descending nerve tracts. Assess the signs and symptoms presented by the patient and identify the exact location of a lesion affecting the brain stem. Correlate the signs and symptoms of pons astrocytoma with nuclei and nerve tracts involved by the tumor. Explain the difference in signs of upper and lower motor neuron lesions affecting the facial motor nucleus. Presented and edited by Dr. Akram Jaffar, Ph.D.

Testimonials

Being focused on new endoscopic techniques in medicine (ESD - endoscopic submucosal dissection), I understand well the need to promote the latest innovation and discoveries. I recommend MEDtube video sharing website for doctors as tool to disseminate techniques and technologies improving doctors' skills and awareness globally. Good luck.

I was excited to discover MEDtube during my online research for video content in ortopedics. Such project was missing. Professional medical education requires more open and innovative approach. I will use the platform in my teaching activities and publish own content. I look forward to joint projects with MEDtube and promise my personal support in Hong Kong and continental China. Good luck!

Shekhar Kumta,

Orthopaedic Surgeon, Dir. of the Teaching & Learning Resource Centre, The Chinese University of Hong Kong, China

I have devoted my long professional career to technology harvesting of innovation in medicine and new technologies in surgery. One of the most difficult barriers to innovation has been the real-time access to information about the rapidly emerging new technologies. It is this inefficiency in the timely availability of announcements of new discoveries that has slowed the diffusion of new technologies and impaired their early adoption.. MEDtube is a powerful new platform that provides healthcare professionals a much more immediate exposure to such new technologies. MEDtube is a welcome addition of rapid access to trusted healthcare knowledge and early discovery which is as much of a game-changers as the innovations which they report.
