Document Summary

2 classic symptoms counter anaphylactic shock: sympathetic/parasympathetic tone , enteric nervous system causes vasodilation. Decrease in blood pressure (can lead to breathing) These effects are controlled by beta receptors, which are more responsive to epi, so give epi to. Basal rate of neuron discharge (about 1 ap per few seconds; can reach about 20 aps/sec); much lower tone than those of the somatic ns. Allows a single system to increase & decrease activity of stimulated organ. For arterioles, increased discharge causes vasoconstriction, and decreased discharge. Isoproterenol = manufactured adrenergic agonist: goal of drug companies is to manufacture specific agonists/antagonists to specific receptors and receptor subtypes relaxation) Alpha-adrenergic receptors can be excitatory (vasodilation) or inhibitory (iris dilation, intestinal. Beta-adrenergic receptors can be excitatory (heart acceleration) or inhibitory (bronchodilatation: adrenal medulla secretes nor/epinephrine (80% epi; has a greater effect on heart because heart has beta receptors, which respond to epinephrine much more strongly than norepi)

Hi this is the introduction that I have written for my poster. Myposter is on the following URL (please have a look!).

Please correct the introduction for any scientific or grammaticalerrors and give me your suggestions about this section as well asthe overall poster. Thanks

This is very important so if you are not good at it pleasedon't answer.

Here is the introduction :

Have you ever thought about why would thrilling rides getyou excited, make your heart racing orsometimes even make you start screaming from the depths of yourcore, forming a bead of sweat on your forehead?

Well, the answer lies in physics. These rides demonstratevery good examples of the physics laws and concepts involved innature and their affect on us in real life applications.

Height, weightlessness, high velocity, hugeacceleration, the sudden impulse and themomentary change in momentum, the work being done and the suddenchange in energy are all factors that contribute inmaking a thrilling ride an exciting one. Those factorsmake adrenalin concentrations in our body system increasecausing higher blood pressure thus stimulating theheart.. They also make the rider in a lot ofuncertainty and unexpected visual cues.

An example of a thrilling ride is the Giant Drop which isa freefall ride involving the drawing of an eight seat carriage bytwin cables to the top of the tower. After one minute full ofanxiety, the riders are plummeted down a height of 39 stories(almost 115m) then brought to a halt within meters from the groundby a sophisticated magnetic braking system.
