The Ear, altho' not usually endu'd with any sensible Motion, nevertheless hath four Muscles, viz. one above, and three behind; the first being situated over the Temporal, and fasten'd to the Ear to draw it upward: The three others have
their beginning in the Mammillary Apophysis, and are terminated in the Root of the Ear, to draw it backward.
There are also three Muscles in the inner part of the Ear, whereof the external belonging to the Malleus or Hammer lies under the exterior part of the Bony Passage which reacheth from the Ear to the Palate of the Mouth, being fixt in a very oblique Sinuosity which is made immediately above the Bone that bears the Furrow, into which is let the Skin of the Tympanum or Drum. The internal Muscle lies hid in a Bony Semi-Canal, in the Os Petrosum; one part of which Semi-Canal is without the Drum, and clos'd on the top with a Passage that leads from the Ear into the Palate. But the other part within the Drum advanceth to the Fenestra Ovalis, and is inserted in the hinder part of the Handle of the Malleus. The Muscle of the Stapes or Stirrup is also hid in a Bony Tube, almost at the bottom of the Drum, and fixt in the Head of the Stapes.
The Nose hath seven Muscles, that is to say, one common and six proper; the common constitutes part of the orbicular Muscle of the Lips, and draws the Nose downward with the Lip. Of the six proper Muscles of the Nose, four serve to dilate it, being situated on the outside, and two to contract it, which are placed in the inside.
The two first Dilatators of a Pyramidal Figure, take their rise in the Suture of the Forehead, and are fasten'd by a large Filament to the Alæ of the Nose. The two other Dilatators resembling a Myrtle-Leaf have their Source in
the Bone of the Nose, and are inserted in the middle of the Ala.
The two Restrictors are Membranous, beginning in the internal part of the Bone of the Nose and adhering to the inner Ala of the Nostril.
The Lips have thirteen Muscles, viz. eight proper, and five common: Of the proper there are four for the Upper-Lip, and as many for the Lower: with two common for each, and the odd one.
The first of the proper of the Upper-Lip bears the Name of the Incisivus, its Origine being in the Jaw, in the place of the Incisive Teeth and its Insertion is in the Upper-Lip.
The second is the Triangulis, Antagonist to the former; its Rise is on the outside, at the bottom of the Lower-Jaw; and it is implanted in the Upper-Lip, near the Corner of the Mouth.
