Explain both the anatomical and functional divisions of the nervous system. Include the subdivisions of each.

Hi, everyone. Welcome back. Let's look at our next question. Which subdivision of the autonomic motor division is responsible for preparing the body for stress or danger. A parasympathetic b, sympathetic C somatic motor or D visceral sensory. So let's recall it. The autonomic motor division is that subdivision of the nervous system that is responsible for controlling involuntary processes. And there are two subdivisions, the parasympathetic and sympathetic subdivisions of the autonomic motor division. So we can actually eliminate choice of CND because those are not subdivisions of the autonomic motor division. They are types of neurons. So, somatic motor neurons have to do with um voluntary movement of the skeletal muscles. But again, that's a type of neuron, not a subdivision. So not a correct answer. And visceral sensory neurons are ones that give the brain sensory information from internal organs, but obviously not the answer we're looking for. So we'll cross that off. So now we have to distinguish between the parasympathetic or sympathetic divisions and we're looking for the division responsible for preparing the body for stress or danger. This is perhaps more well known as the flight or fight response and that is governed by the choice be sympathetic system or division. And so that's going to be our correct answer. We will eliminate the parasympathetic subdivision, which is responsible for what we might call the rest and digest mode when the body is not in danger and can be resting and the death digestive processes can be going on. Whereas those processes will not be taking place in times of stress or danger when the sympathetic nervous system and choice B takes over. See you in the next video.
