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.
CN-IX, X XI and XII to the medulla. Some cranial nerves are purely afferent (sensory); others are entirely efferent (motor); and some are mixed (both sensory and motor). Olfactory Nerve (CN-I): Sensory for smell. It passes through the cribriform plate of the ethmoid bone. Elderly people.
