    • What Are Cranial Nerve ? Nerve arise from brain called cerebral or cranial nerve
    • Type For Cranial Nerve ?  For Leaning Cranial Nerve Name There Is Small Term Called “OOOPTAFAGVAH” , In Which All Cranial Nerve first Name Letter included  There Are Two Main Type Of Cranial Nerve Found According To Number , They May Be “X” Or “XII” In Number
    • Number Of Cranial Nerve ? In Chordates :- • Agantha (jaw less) = 8-10 pair cranial nerve • Gnathostomata = 10-12 pair of cranial nerve • In Pieces Chondrichthyes (Cartilaginous fish ) = 10 pair • In Pieces Osteichtyes (Bony fishes ) = 10 pair • In Amphibian = 10 pair • In Reptilia = 12 pair • In Aves (Birds) = 12 pair
    • Defects Of Cranial Nerve ?  Olfactory Nerve (Cranial Nerve I) - Anosmia (loss of the sense of smell), hyposmia (a decreased sense of smell)  Optic Nerve (Cranial Nerve II) - Immediate monocular blindness (partial or complete)  Oculomotor Nerve (Cranial Nerve III) - Oculomotor nerve palsy, including isolated and bilateral oculomotor nerve palsies  Trochlear Nerve (Cranial Nerve IV) - Injury to the trochlear nerve can cause vertical diplopia on looking downward which improves with contralateral head tilt and worsens with ipsilateral head tilt
    • Defects Of Cranial Nerve ?  Abducens Nerve (Cranial Nerve VI) - In a complete injury of the abducens nerve, the affected eye is turned medially. In an incomplete injury, the affected eye is seen at midline at rest  Trigeminal Nerve (Cranial Nerve V) - Corneal drying, abrasions, and/or pain, decreased salivation, and, especially, anesthesia of the forehead, eyebrow, and/or nose can occur following TBI  Facial Nerve (Cranial Nerve VII) - Complete or partial paralysis of the face, hyperacusis, and/or an unusual or impaired sense of taste can occur following TBI
    • Defects Of Cranial Nerve ?  Vestibulocochlear Nerve (Cranial Nerve VIII) - Positional vertigo is the most common problem, although tinnitus, hearing loss, and deafness may also occur following TBI  Hypoglossal Nerve (Cranial Nerve XII) - Dysarthria and swallowing difficulties
