    ******CORRECTION***** at 32:31 I stated that the preganglionic parasympathetic motor neurons that occupy the interomediomedial nucleus at S2-S4 supply cardiac muscle. THAT COULD NOT BE MORE WRONG!! I must have had a huge brain fart when I wrote that!!! Very sorry Ninja Nerds!!! TO CLARIFY!!! Cardiac muscle is ONLY supplied by preganglionic motor neurons of the sympathetic nervous system from T1-T5 spinal Cord level and the Vagus nerve which is Cranial Nerve X is the parasympathetic supply to the cardiac muscle. SO to end it all off, S2-S4 preganglionic motor neurons which occupy the Interomediomedial Nucleus ONLY supply Smooth muscle and Glands!!! Alright Ninja Nerds sorry again!!! Hope this makes sense and clears up any confusion!!!

      Please tell me the ans,
      The following items are related to each other in a hierarchical fashion: chromosome, base pair, nucleosome,kilobase pair, intron, gene, exon, chromatin, codon, nucleotide, promoter. What are these relationships?

    Zach. I just wanted you to know, you are simply an amazing man. To make all these videos for free, to educate people who arent able to pay for tuition fees, and to keep on posting videos with that enthusiasm, I salute you. Please never doubt yourself and never feel discouraged. I managed to pass in my exams because of you. I began to understand more about the human anatomy because of your dedication in posting these videos.

    Man everything is coming together so neatly.
    Notice the playlist organises eacb segment which eloraborates and builds on the next one, like a tangible body of information to step upon akin to solid ground.
    The explanations are so indepth, with about 30 notepads and a few pens, you can copy everything a few times over and learn an entire university course worth tens of thousands of pounds or dollars in your own local library or bed room.
    I just think this man is amazing, to rember this amount of specilised knowledge then explanatorily communicate it so the mere mortal humans such as ourselves can innerstand this speckalised knowledge.

    I used to call myself an anatomy buff, but my knowledge of the CNS stopped at cerebral landmarks and nuclei, and large nerve plexus and bundle groups - the spine has always been a blackhole of knowledge for me and spinal cord features feel like a whole new world to explore. 🤯 Wow, this was a great vid - I'm glad I joined your patreon. 🙏
