190 PRACTICAL ANATOMY. 



Insertion The fibres pass backward, upward, and 

 inward ; they meet those of the opposite muscle 

 behind the pharynx, and are inserted into the 

 tendinous raphe of the pharynx, which is at- 

 attached to the pharyngeal spine of basilar process 

 of occipital. 



Nerve Glosso-pharyngeal. 

 MIDDLE CONSTRICTOR. 



Origin Greater and lesser cornu of hyoid bone and 

 stylo-hyoid ligament. 



Insertion Passes outward and backward and meets 

 the muscle of opposite side, and is inserted into the 

 tendinous vertical raphe. 



Nerve Glosso-pharyngeal. 

 INFERIOR CONSTRICTOR. 



Origin Side of thyroid and cricoid cartilages. 



Insertion Passes outward and backward and meets 

 fibres of opposite muscle, and is inserted into the 

 tendinous vertical raphe. 



Nerves Glosso-pharyngeal and external laryngeal. 

 STYLO-PHARYNGEUS. 



Origin Styloid process. 



Insertion Sides of pharynx between superior and 

 middle constrictors. 



Nerve Glosso-pharyngeal. 

 RECTUS CAPITIS ANTICUS MAJOR. 



Origin Anterior tubercles of transverse processes of 

 third, fourth, fifth, and sixth cervical vertebrae. 



Insertion Basilar process of occipital. 



Nerve Suboccipital. 

 RECTUS CAPITIS ANTICUS MINOR. 



Origin Lateral mass of atlas. 



Insertion Basilar process. 



Nerve Suboccipital.
