  Cranial Nerves As we already know, cranial nerves consist of 12 nerves. These nerves originate from the different parts of the brain, mainly from the brainstem. Cranial nerves supply different parts of the body and any kind of damage to these nerves may cause a medical anomaly. Some of the clinical conditions that can occur to these nerves are described below; FOR NOTES OF CRANIAL NERVES :  CRANIAL NERVES Olfactory Nerve  Inability of the nose to sense any smell is known as Anosmia . It may be unilateral or bilateral. Causes Unilateral Anosmia Damage to olfactory mucous, nerve or tract Olfactory Cortex lesion Fracture of Ethmoid bone (Ant Cranial fossa) Frontal lobe lesions (As they can press the nerve below them) Bilateral Anosmia Common Cold Allergic Rhinitis (Diseases of the olfactory mucous membrane) Optic Nerve Optic nerve mainly makes us able to see. The optic pathway may be damaged at different spots that creates a wide range of effects that can be observed. Circumferential B

  CRANIAL NERVES There are 12 pairs of nerves that arise from the brain itself and are termed as the Cranial Nerves. Cranial nerves emerge from different parts of the brain and follow many different pathways to reach their destinations. The movement of eyes, tongue, facial expressions as well as the visceral control of organs are the few tasks carried out by Cranial nerves. Content The twelve pairs of Cranial nerves are: Olfactory Nerve (CN I) Optic Nerve (CN II) Occulomotor Nerve (CN III) Trochlear Nerve (CN IV) Trigeminal Nerve (CN V) Abducens Nerve  (CN VI) Facial Nerve (CN VII) Vestibulocochlear Nerve (CN VIII) Glossopharyngeal Nerve (CN IX) Vagus Nerve (CN X) Accessory Nerve (CN XI) Hypoglossal Nerve (CN XII) Following link contains a pdf that has all hand drawn schematics of the pathways of Cranial Nerves; Cranial Nerves (Notes) For more details, please visit the following link https://www.youtube.com/watch?v=nbapZdjrAl0&list=PLEOTysv-tAiCJ86-mbe5zdqx3GgAwHNCz Prepared by; M
