    Transcript
    In this lecture, you are going to learn about the organisation of the nervous system. The structure of the nerve cell or neuron and also the structure of the spinal cord. At the end of this lecture, you should have a very good understanding of the structure of the nerve cell or nerve fibre. You should know the anatomical and functional divisions of the nervous system. And finally you should be able to describe the histological structure of the spinal cord and also be able to identify its functional components. Well, the nervous system is really important and its essential function as you would all be aware of is one of communication. And through the next two lectures, I will be explaining to you structural and functional components that allow us to perceive various information, both consciously and subconsciously. And how the brain then receives that information and then evokes responses, either motor responses bringing about movement or responses that we are unaware of that control many of our body processes, secretion of glands, movement of food through the gut, blood through the vascular system etc. Well, it is very important that we first of all start with the description of the divisions of the nervous system. And although this is very complex I am going to try and take it slowly and trying to explain it in a number of different sections. First of all, we can divide the nervous system anatomically. It consists of two parts. One is the central nervous system. We abbreviate CNS, and that consist of the brain and the spinal cord. The brain is protected inside the cranium, the skull and the spinal cord is protected by the vertebral column. The peripheral nervous system, abbreviate PNS, consists of cranial nerves, spinal nerves and peripheral...

    It's like listening to Siri narrate a Wikipedia article
    By David D. on 18. May 2017 for Nerve Tissue: Organisation of the Nervous System, Neuron and Spinal Cord

    I can't follow the lecturer; his pauses and breaks are distracting from the material. All of his material sounds like he's reading off of a teleprompter
