Posterior Branch of Coccygeal Nerve

The posterior division of the coccygeal nerve does not divide into a medial and a lateral branch, but receives a communicating branch from the last sacral; it is distributed to the skin over the back of the coccyx.

Famous quotes containing the words branch and/or nerve:

    “In communist society, where nobody has one exclusive sphere of activity but each can become accomplished in any branch he wishes, society regulates the general production and thus makes it possible for me to do one thing today and another tomorrow, to hunt in the morning, fish in the afternoon, rear cattle in the evening, criticize after dinner, just as I have a mind, without ever becoming hunter, fisherman, shepherd or critic.”
    —Karl Marx (1818–1883)

    “There must be some nerve and heroism in our love, as of a winter morning.”
    —Henry David Thoreau (1817–1862)
