SISTEMA NERVOSO - FISIOLOGIA - Aula | Biologia com Samuel Cunha

Before class, I want to give you a message. Did you know that Professor Samuel now has a complete biology study platform? This platform has all the biology classes, lists with commented exercises in a study guide, summaries, and simulations—something very important: a study plan. And I'll tell you something else: we have many other new features,

all so you can ace the ENEM or university entrance exams. Don't know about it? Access it here; the link is in the video description. I'll see you there. And now, enjoy the video lesson. See you soon! [Music] Hey

everyone, how's it going? Welcome to another video lesson. Today we're going to talk about the nervous system, which for some is terrifying; some people don't like it, but I actually love all the systems in the field, especially this one, because we understand how our body and our eyes are controlled, how the division is done, and we

know the importance of the nervous system. So much so that if you have a spinal cord injury, if you break your spine, you lose movement downwards and it doesn't recover. Because in biology, we have a maxim that the greater the complexity of a tissue, the lower its regenerative capacity. Because the nervous system is highly

specialized, it has a very low regenerative capacity. It's different from, for example, a starfish, which does n't have complex tissues and can regenerate much more easily. This is something you have to take to heart: the more complex the tissue, the worse its regeneration. This is an example of an extremely specialized tissue, one that is

fundamentally our body. You are listening and absorbing; I hear with my ears, with my hearing. In fact, the ear is nothing more than a mechanism for sending a nerve stimulus to your brain to interpret. Ultimately, you feel, taste, see, hear—everything is through the brain. And this here, this here, are tools that carry, that transform, and the human body
