Functions of Cerebrospinal Fluid

• Mechanical protection

• Chemical protection

• Circulation

Ventricles cerebrospinal fluid flows through

1. Lateral ventricles.

2. Foramina of Monro

3. Third ventricle.

4. Cerebral aqueduct (aqueduct of Sylvius).

5. Fourth ventricle

6. Foramina of Luschka (lateral apertures)

7. Foramen of Magendie (median aperture).

Cranial Nerve 1: Olfactory Nerve

Sense of smell

Cranial Nerve 2: Optic Nerve

Vision

Cranial Nerve 3: Oculomotor Nerve

Eye movement (most eye muscles), pupil constriction, and eyelid elevation

Cranial Nerve 4: Trochlear Nerve

Eye movement (superior oblique muscle)

Cranial Nerve 5: Trigeminal Nerve

Facial sensation (touch, pain, temperature), chewing muscles.

Cranial Nerve 6: Abducens Nerve

Eye movement (lateral rectus muscle).

Cranial Nerve 7: Facial Nerve

Facial expression, taste (anterior two-thirds of the tongue), tear and saliva production.

Cranial Nerve 8: Vestibulocochlear Nerve

Hearing and balance

Cranial Nerve 9: Glossopharyngeal Nerve

Taste (posterior one-third of the tongue), swallowing, saliva production.

Cranial Nerve 10: Vagus Nerve

Sensory and motor functions in the viscera (internal organs), including heart rate, digestion, and respiratory rate.

Cranial Nerve 11: Accessory Nerve

Neck and shoulder muscle movement.

Cranial Nerve 12: Hypoglossal Nerve

Tongue movement.

Meninges

Connective tissue layers that surround the brain and spinal cord, including the dura mater, arachnoid mater, and pia mater.
