Re: Egg. The egg on the Seder plate and the egg that we eat are symbolic of two different things. The egg on the Seder plate symbolizes the special offering that was brought on Festivals when the Jewish people would visit the Temple, the Chagigah offering.here is no obligation to eat eggs at the Seder as it is merely a custom, and if one is allergic to eggs there is no need to eat them. Even if one does not eat the egg, it should still be present on the Seder plate, to commemorate the Chagigah offering.
The first two pairs arise from the cerebrum while the other ten pairs emanate from the brainstem. As in the case of spinal nerves which are named based on their origin from the spinal cord, cranial nerves derived their name from their close association with the cranium.
It can be viewed as the only visible part of the brain (or extension of it). The optic nerve is the second cranial nerve. The cranial nerve emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column. There are twelve cranial nerves.
