Question

is it possible to tell me if I'm correct for the pathway of cranial nerves?

Olfactory : telencephalon-cribirform-olfactory bulbs

Optic: retina-optic canal-occipital lobe

Oculomotor: cranium-SOF-eye

Trochlear: cranium-sof-superior oblique

Trigeminal: pons-sof-muscles of mastication

Abducens: cranium-sof-lateral rectus

Fascial: pons-stylomastoid foramen-temp bone

V/lear: cochlea-internal accoustic meatus,braistem

Gl/al: tongue- JF-pons

Vagus: medulla-jf-thorax

Accessory : medulla-jf-neck muscles

Hypoglossal: medulla-hypoglossal-mandible

Explanation / Answer

The pathways are corrected here:

Olfactory : telencephalon-cribirform-olfactory bulbs- olfactory tract -primary olfactory cortex

Optic: retina-optic canal-occipital lobe

Oculomotor: cranium-ventral midbrain--SOF-four extrinsic muscles of eye

Trochlear: cranium- dorsal midbrain-sof-superior oblique muscle

Trigeminal: pons (ophthalimic, maxillary and mandibular)-sof-muscles of mastication

Abducens: cranium-fibers from inferior pons-sof-orbit-lateral rectus

Facial: pons-stylomastoid foramen-temp bone-branches for taste -lateral side of face

V/lear: cochlea-internal accoustic meatus-brainstem (afferent nerves form cochlear division, equilibrium receptors form vestibular division)

Gl/al: tongue- skull JF- throat area

Vagus: medulla-skull jf- thorax and abdomen

Accessory : lateral side of medulla and spinal cord-jf-neck muscles

Hypoglossal: roots from medulla-hypoglossal canal-tongue muscle

---------------------------------------------------------------------------------------

Olfactory sensory nerves exit from the foramina of cribriform plate.

Optic nerves synapse on thalamus and run to occipital cortex. Sensory nerves that exit from optic canal

Occulomotor motor nerves that exit through SOF

Tochlear motor nerves that exit through SOF

Opthalmic, maxillary and mandibular nerves also called trigeminal nerves that exit through SOF, foramen rotundum, foramen ovale. They are both sensory and motor

Abduscens motor nerves that exit through SOF

Facial motor and sensory nerves exit through internal acoustic meatus

Vestobulocochlear sensory nerves that exit through internal acoustic meatus

Glossopharyngeal sensory and motor nerves that exit through jugular foramen

Vagus sensory and motor nerves that exit through jugular foramen

Accessory motor nerves that exit through jugular foramen

Hypoglossal motor nerves that exit through hypoglossal canal
