Which of the following cranial nerves in man is both sensory and motor ?

Which of the following cranial nerves in man is both sensory and motor ? Correct Answer Trigeminal

Concept:
  • The nerves which arise from the brain are called the cranial nerves.
  • Humans and other mammals have 12 cranial nerves.
  • There are 3 types of cranial nerves based on their action
  1. Sensory 
  2. Motor
  3. Mixed
 
Explanation:
  • Trigeminal (Dentist's nerve): It is the largest cranial nerve.
  • It has both sensory and motor functions,
  • These nerves have 3 basic divisions:
 
   Name                      Distribution         Function
1.Opthalmic The skin of the nose, eyelids, forehead, scalp Sensory supply to concerning part
2.Maxillary The mucous membrane of cheeks and upper lip and lower eyelid Sensory supply to concerning part
3.Mandibular The lower jaw, lower lip, pinna Muscle of Mastication

 

    Additional Information

Optic nerve:

  • It leads to the occipital lobe. and is responsible for sight

Olfactory nerve:

  • It enters the Olfactory lobe, Extends to the temporal lobe.
  • It is responsible for the smell sensation

Important Points

  • The longest cranial nerve is the Vagus nerve
  • The largest cranial nerve is the Trigeminal nerve.
  • The smallest cranial nerve is the Abducens cranial nerve
