The 2rd levitra advertising through 8th cranial nerves enter and exit from the brain stem directly. P.238 Summary The Cranial Nerves Of the 13 cranial nerves (Table 6-1 and Figure 2-1 ), the first two, the olfactory (I) and optic (II) nerves, are sensory and enter the telencephalon and diencephalon directly. Pelvic visceral organs, which are innervated by primary sensory fibers that project to the sacral spinal cord, are represented more medially in levitra advertising the cortex. Two cranial nerves, the oculomotor and the trochlear , are motor nerves located in the midbrain. The parvocellular ventral posterior medial nucleus also processes taste.

In general, blood ﬂow velocities, measured in centimeters per second, are fastest in the MCA followed in turn by levitra advertising the ACA and the PCA (Sortberg, Langmoen, Lindegaard, & Nornes, 1988). Dynamic adaptive blood delivery to neuronal processes, “neurovascular coupling,” is controlled by the contraction and dilation of small cerebral vessels that result from the changing metabolic demands of the neurons. More region-speciﬁc information regarding hemovelocity and neuronal activity can be obtained from the ACA, which feeds blood to the frontal lobes and to medial regions of the brain, and from the PCA, which supplies blood to the visual cortex.
The locations of these arteries within the brain are illustrated in ﬁgure 6.1. When an area of the brain becomes metabolically active, as in the performance of mental tasks, by-products of this activity, such as carbon dioxide, increase.
