37. There are 6 extrinsic muscles of eye: They are:
1. Superior rectus muscle which rotates eye medially and upwards.
2. Inferior rectus muscle which rotates eye medially and downwards.
3. Medial rectus muscle which rotates eye medially.
4. Lateral rectus muscle which rotates eye laterally.
5. Superior oblique muscle which rotates eye laterally and downwards.
6. Inferior oblique muscle which rotates eye laterally and upwards.
Eye movements are controlled by muscles which are innervated by cranial nerves III, IV and VI.
*The medial, inferior, superior rectii and inferior oblique are innervated by occulomotor nerve(III)
*The superior oblique muscle is innervated by trochlear nerve(IV)
*The lateral rectus muscle is innervated by abducens nerve(VI).
39.It is by cranial nerve V i.e . Mandibular branch of trigeminal nerve.
40.Cranial nerve V i.e. trigeminal nerve helps in chewing.It is termed as largest cranial nerve.
41. Somatic, its cranial nerve is I.i.e olfactory nerve.
42. Autonomic, its cranial nerve is II i.e optic nerve.
43. Swallowing is a function of cranial nerve IX i.e glossopharyngeal and head movements is a function of cranial nerve XI i.e accessory.
