284 ELEMENTARY ANATOMY. [LESS. 



auriculam, the retrahentes auriculam, and the zygomato- 

 auricularis, arise from above, behind, and in front of the ear, 

 to the external part of which they are attached. In rare 

 cases a man is able to move his ear by the contraction of 

 these muscles. 



The orbicularis palpebrarum is a muscle which surrounds 

 the eye beneath the skin, and is not attached to any bone 

 except at the inner margin of the orbit. By its contraction it 

 closes the eyelids. 



A little muscle, the levator palpebrtz, takes origin deep in the 

 orbit (above the optic foramen), and is inserted into the upper 

 eyelid, which it raises, No analogous muscle depresses the 

 lower eyelid. 



Other muscles of man which are connected with the lips 

 or nose are : I. Pyramidalis nasi. 2. Levator labii supe- 

 rioris alceque nasi. 3. Compressor nan's. 4. Depressor 

 alee nasi. 5. Levator proprius alee nasi. 6. Levator labii 

 superioris (which takes origin from the maxilla and malar). 

 7. Levator anguli oris (arising below the infra-orbital fora- 

 men). 8. Zygomaticus minor (going from the malar to join 

 No. 6). 9. Zygomaticus major (going from the malar to the 

 angle of the mouth). 10. Depressor anguli oris (springing 

 from the mandible), n. Depressor labii inferioris (placed 

 near the front of the lower jaw.

 i, temporal ; 2, corrugator supercilii ; 3, transversalis nasi ; 4, depressor alse nasi ; 

 t;, levator anguli oris ; 6, buccinator, traversed towards its hinder part by the 

 duct of the parotid gland ; 7, depressor labii inferioris ; 8, levator menti; 9, 

 masseter, cut short near its insertion ; 10, external lateral ligament. 



The buccinator is a thin flat muscle extending between the 

 alveolar margins of the jaws on each side.
