4. Yachatz (Breaking the Matzah) - There is always a plate of three matzot (plural of matzah) on the table during a seder. (These matzot are part of the ritual meal-there are other matzot elsewhere to feed the seder guests.) At this point the seder leader takes a piece from the middle of the plate and breaks it in half.The smaller piece is put back between the remaining two matzot.These matzot are part of the ritual meal-there are other matzot elsewhere to feed the seder guests.)

Nerve fibres of the parasympathetic nervous system arise from the central nervous system. Specific nerves include several cranial nerves, specifically the oculomotor nerve, facial nerve, glossopharyngeal nerve, and vagus nerve. Three spinal nerves in the sacrum (S2-4) also act as parasympathetic nerves.he vagus nerve is an unusual cranial parasympathetic in that it doesn't join the trigeminal nerve in order to get to its target tissues. Another peculiarity is that the vagus has an autonomic ganglion associated with it at approximately the level of C1 vertebra. The vagus gives no parasympathetic to the cranium.
Vagus Nerve is one such cranial nerve that also happens to be the longest nerves in the body that innervates the throat, thorax, abdominal muscles and other organs and has several functions, which is why it is one of the most important parts of our nervous system.he vagus nerve is two nerves that go through the brain stem and enter different parts of the body such as the heart and the stomach. Vagus nerve leaves the brain stem from the rootlets present in the medulla that has been found to be caudal to the rootlets in the ninth carnial nerve.
