Which cranial nerves’ sensory branch enervate baroreceptors and chemoreceptors located in the aortic and carotid bodies? What are baroreceptors and chemoreceptors ?
Little addition: this is a beautiful page for ventilatory control, nerves and chemoreceptors along with pictures (Central and peripheral explained). I find pictures the easiest to learn off personally, but everyone's different. Have a read... there's lots of detail you might not need, but it's also pretty simple to pull the basics out of. Scroll through all the pictures... at least 2 will be very useful, I think. x
I hope I'm right about this cause I really should know the answer.
CN 9 and 10.
Baroreceptors respond to changes in blood pressure and can trigger alterations in heart rate and vessel diameter to keep blood pressure in a steady range.
Chemoreceptors, if I'm not mistaken, respond to oxygen and even carbon dioxide (and also pH in the carotid body) and can induce alterations in ventilation.
It's cool if it's unique, but a lot of the time it's just something that's been done before. Or it's half a big gesture, like he tried to do something special to seem cool but was afraid to get too crazy. If you're going to do it, then do it all the way! Also, when it's a big promposal in front of a bunch of people, I imagine it would be a lot of pressure to say yes, which is unfair. Most importantly, it depends on the person your asking's personality. Would they really want to be asked the way that you're thinking of? If not, then don't do it - you're only thinking about yourself(trying to show off to other people). I personally would hate a public promposal, but a personal one away from other people might be nice. Don't go over the top if that person doesn't like over the top.
CN 10, the vagus nerve. Baroreceptors sense arterial blood pressure and send signals to alter you heart function and the tone of your blood vessels. They help your body respond to situations that demand changes in blood pressure (e.g. when go from lying down to standing up your blood pressure has to respond quickly to the change in your position with respect to gravity otherwise the bloodflow to your brain would change all of a sudden and you would pass out). Chemoreceptors sense chemicals like oxygen and metabolic waste products (e.g. lactic acid), they monitor your blood to make sure your brain and other organs are getting oxygen in and waste products out at an appropriate rate. If they sense that oxygen is too low or waste products are too high they increase blood flow to improve that, this is why your heart rate speeds up when you excercise. Slice is right, I belive that chemoreceptors also affect your respiratory system for the same reasons of getting oxygen in and waste products out.
