This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Unknown
All the following are true regarding 5th cranial (Trigeminal) nerve except: 
Select and explain. 
A. Arises from midbrain, B. Innervate muscles of mastication, C. Carries parasympathetic fibres to salivary glands, D. Provides sensory innervation to face
A: Arises from midbrain
Answer: A: Arises from midbrain 
Explanation: (Refer: Richard S. Snell’s Clinical Anatomy by Regions, 9th edition, pg no: 607- 610)
Trigeminal nerve

Mesencephalic nucleus is situated in midbrain, spinal nucleus of trigeminal it extends from pons to C3 segments.
It carries parasympathetic fibres to salivary glands.
Four peripheral parasympathetic ganglia (Ciliary, otic, pterygopalatine and submandibular) are topographically connected with 3 divisions of 5th cranial nerve, but they are not functionally related to it.
Pterygopalatine ganglia connected with maxillary nerve (supplies minor salivary glands-pharyngeal and palatine glands).
Otic ganglia connected with mandibular nerve (supplies parotid gland).
Submandibular ganglia connected with lingual nerve (branch of mandibular)-(supplies submandibular and sublingual gland).
Trigeminal nerve (mixed nerve) has large sensory root laterally and small motor root medially.
Mandibular division (has both motor and sensory) of trigeminal nerve innervate muscles of mastication.
Ophthalmic division and maxillary division are purely sensory.
All 3 division-ophthalmic, maxillary and mandibular division provides sensory innervation of face.
