MUSCLES OF THE TRUNK. 275 each other at the commissures of the mouth, and confounded with the superficial layer of the buccinator, which they appear to continue, these two muscular por- tions also receive a large portion of the fibres belonging to the majority of the extrinsic muscles, such as the dilatator naris lateralis and levator labii superioris aliequi nasi. The orbicularis is not attached to the neighbouring bone ; its component fibres, affecting a circular form, have, consequently, neither beginning nor ending, except in being continuous with other fibres. The internal face of the superior fasciculus responds to a layer of salivary glands, which in part separate it from the buccal mucous membrane. The external, covered by the skin, adheres to it in the most intimate manner, and is found isolated from it only on the median line, at first by the aponeurotic expansion of Fig. SUPERFICIAL MUSCLES OF THE FACE AND HEAD. 1, Temporo-auricularis externus, or attollens maximus; 2, levator palpebrae, or corrugator super- cilii; 3, temporo-auricularis internus, or attollens posticus; 4, 5, zygomatico-auricularis, or attollens anticus; 6, orbicularis palpebrarum; 7, abiiucens, or deprimens aurem; 8, parotid gland; 9, temporal, or subzygomatic vein; 10, ditto, artery; H, 12, superior and inferior maxillary nerves- 13, fascia of the masseter muscle; 14, nasal bones; 15, supernasol-abialis, or levator labii superioris alaque nasi; 16, supermaxillo-labialis, or nasalis longus labii superioris; 17, external maxillary or facial artery; 18, facial vein; 19, supermaxillo-nasalis magnus, or dilatator naris lateralis ; 20, superior maxillary nerve ; 21, zygomatico-labialis, or zygomaticus; 22, parotid, or Steno's duct; 23, masseter; 24, alveolo-labialis, or buccinator; 25, super- maxillo-nasalis parvus, or nasalis brevis labii superioris; 27, labialis, or orbicularis oris; 28, maxillo-labiali
