what is the secret of the face of boe
Face of Boe The Face of Boe's ostensible last appearance is in "Gridlock" (2007), in the year five billion and fifty-three, some time after a drug-induced plague has wiped out almost all life on New Earth. He had been using his life force to power the undercity of New New York, which was sealed off from the rest of the planet to save the only survivors from the now-extinct virus. The Face of Boe needed the Doctor's help to free the people from the undercity, and he uses the last of his life energy to provide a power boost to unseal the exits. As was foretold in legend, initially introduced in spin-off media, the sky (of the undercity) splits asunder just before the Face of Boe dies. In his final moments, the Face of Boe reveals his great secret to the Doctor: "You are not alone." The Doctor tells his companion, Martha Jones, that the Face of Boe must be mistaken, but it is later revealed that there is indeed another Time Lord â€” the Master has survived the Time War.
Salivary gland The two parotid glands are major salivary glands wrapped around the mandibular ramus in humans. The largest of the salivary glands, they secrete saliva to facilitate mastication and swallowing, and amylase to begin the digestion of starches. It is the serous type of gland which secretes the ptyalin. It enters the oral cavity via the parotid duct or Stensen duct. The glands are located posterior to the mandibular ramus and anterior to the mastoid process of the temporal bone. They are clinically relevant in dissections of facial nerve branches while exposing the different lobes of it since any iatrogenic lesion will result in either loss of action or strength of muscles involved in facial expression. They produce 20% of the total salivary content in the oral cavity.
