140 HUMAN ANATOMY. 



PALATO-PHARYNGEUS. Origin,, by two portions, from soft 

 palate; insertion, into posterior border of thyroid cartilage and 

 pharynx; this muscle forms the posterior pillar of the fauces; 

 action, closes the posterior nares ; nerves, palatine branches from 

 MeckePs ganglion. 



VERTEBRAL REGION". 



EECTUS CAPITIS ANTICUS MAJOR. Origin, by four tendons 

 from transverse processes of the third, fourth, fifth, and sixth 

 cervical vertebra; insertion, basilar process of occipital bone; 

 action, flexes the head; nerves, suboccipital and deep internal 

 branches of cervical plexus. 



EECTUS CAPITIS ANTICUS MINOR. Origin, from root of 

 transverse process and anterior part of the lateral mass of the 

 atlas; insertion, basilar process of occipital, behind the former; 

 action, flexes the head; nerves, suboccipital and deep branches of 

 the cervical plexus. 



EECTUS LATERALIS. Origin, superior surface of the trans- 

 verse process of the atlas ; insertion, inferior surface of the jugu- 

 lar process of the occipital; action, draws the head laterally; 

 nerves, suboccipital and deep internal branches of the cervical 

 plexus. 



LONGUS COLLI. Origin, from three portions, superior ob- 

 lique portion from anterior tubercles of the transverse processes 

 of the third, fourth, and fifth cervical; insertion, tubercle on 

 the anterior arch of atlas ; inferior oblique portion, origin, from 

 anterior surface of the bodies of the first two or three dorsal ver- 

 tebrae; insertion, anterior tubercles of the transverse processes 

 of the fifth and sixth cervical; vertical portion, origin, from 

 the anterior surface of the bodies of the lower three cervical and 

 upper three dorsal bodies of the second, third, and fourth cervical 

 vertebrae; action, rotates and flexes the cervical portion of the 

 vertebrae; nerves, anterior branches of the lower cervical nerve. 



SCALENUS ANTICUS. Origin, from the tubercle of the first 

 rib ; insertion, into the anterior tubercles of the transverse proc- 

 esses of the third, fourth, fifth, and sixth cervical vertebrae; 

 action, flexes and rotates the vertebral column; nerves, anterior 

 branches of the lower cervical nerve. 



SCALENUS MEDIUS. Origin, upper surface of the first rib, 

 behind the groove for the subclavian artery; insertion, into the 

 transverse processes of the lower six cervical vertebrae; action, 

 rotates and flexes the vertebral column; nerves, the anterior 

 branches of the lower cervical nerve : the posterior thoracic, long 

 thoracic nerve, or external respiratory nerve of Bell, has its
