The vasovagal response is the development of inappropriate cardiac slowing and arteriolar dilatation. Vasovagal responses reflect autonomic neural changes: bradycardia results from sudden augmentation of efferent vagal activity, and hypotension results from sudden reduction or cessation of sympathetic activity and relaxation of arterial resistance vessels. Two different neural pathways are thought to be involved, one originating in the hypothalamus, the other in the heart. Direct hypothalamic activation of the medullary cardiovascular centres triggered by emotional stress or pain causes a vasovagal response (central type). The combination of a reduced central blood volume secondary to venous pooling or blood loss, and an increased inotropic state of the heart, may stimulate ventricular mechanoreceptors and provoke vasodilatation and bradycardia (peripheral type). Cardiovascular afferents originating from stretch receptors in various parts of the vascular tree sometimes induce opposite reflexes when compared with those from ventricular afferents. The depressor reflex involved in the peripheral type of vasovagal response originates in the heart itself and overrides normal baroreflex circulatory control; an antagonism between the control of volume and pressure on the filling side of the heart and the control system of arterial pressure becomes apparent. Vasovagal responses are not necessarily abnormal; the neural pathways involved in the vasovagal response are probably present in all healthy subjects who individually mainly differ in susceptibility.

Okay.. so, on to what you wrote.

The three cardinal trapezoidal formations hereto made orientable in our diagram by connecting the various points HIGK, PEGQ, and LMNO, creating our geometric configurations which have no properties, but with location...
*pauses for applause*
are equal to the described triangle CAB quintuplicated. Therefore, it is also the five triangles composing the aforementioned NIGH. Each are equal to the triangle CAB in this geometric concept.
*pauses for laugh*
And therefore, in a like manner, the geometric metaphors can derive a repeated vectoral sum. This was your assignment....

We read that kinda stuff in bio. >.< Evil, evil, evil, evil, evil subject.

What's more evil? I have a bio exam in less than a week that I should be studying for :( Not to mention all the others...

But yes, back to you --> sounds painful. My sympathies!

that happened to me once! i had been really sick for a week and i knocked my funny bone and apparently had a vasovagal response and fainted.
just a little embarrassing ; )
