DISSECTION OF THE HEAD. 



head is supplied by spinal nerves (anterior and posterior primary branches), 

 except close behind the ear, where there is an offset of the facial or seventh 

 cranial nerve. 



The supra-orbital nerve (fig. 2, 6 ) comes from the first trunk of the 

 fifth nerve, and escapes from the orbit with its companion artery ; whilst
