SYNOPSIS OF THE MUSCULAR DISTRIBUTION OF THE CEREBRO- 



SPINAL NERVES. 



J . To muscles of the head and fore part of the neck. The muscles ofthfi orbil 

 arc mostly supplied by the third cranial nerve the superior division of that nerve being 



distributed to the levator |)al|>(-br;i! and the HUpcrior IVC,|,IIK inuscleH, and the inferior 

 division to the infi-rior :nid internal rec.ti and tlie inferior oblique. r rii(! Huperior 

 oblique muscle is Huj)plied by the fourth nerve, and the external rectus by the sixth ; 

 wliili UK- tensor tarsi has no special nerve apart from those of the orbieularin 

 pidpebrarinn, wliicli :..n: derived IVoin the fjw.i;!.!. 



The Nii/t(r/iaa/. wmrlcs of I In- face, and scalp, which are associated in their action 

 as a tfronp of muscles of expression, together with the buccinator muscle, are supplied 

 by t he seventh cranial nerve, the retnihens auriculam and occipitalis muscles being 

 supplied by its posterior auricular branch. 



The deep muscle of'thc f<m> employed in mastication, vi/., Uie temporal, masseter, 

 and two pterygoid muscles, are supplied by the inferior maxillary division of 

 the fifth cranial nerve. 



M uncles above ike /////>/ hone. The mylo-hyoid muscle and anterior belly of the 

 digastric are supplied by a branch of the inferior maxillary division of the fifth cranial 

 nerve ; the posterior belly of the digastric muscle and the stylo-hyoid (together with 

 the Htapcdius muscle) are supplied l,y br-.m-lieH of the facial. The muscles of the 

 tongue receive their nervous supply from the hypoglossal nerve ; and the genio- 

 hyoid muscle is supplied (like the infrahyoid muscles) by the upper cervical nerves. 



The mu8clct> ascmdiny to Ike kyoid bone and larynx, viz., the sterno-hyoid, omo- 

 hyoiil, and sterno-thyro-hyoid, are supplied from the upper cervical nerves through 

 their communications with the hypoglossal nerve and the ansa cervicalis.
