6. smell
7. controls neck and shoulder movements
8. controls tongue movements
9. vision
10. stimulates lateral rectus muscle of eye
11. taste, salivation, and secretion of tears
12. swallowing

Explanation:

• Abducens (a): Stimulates the lateral rectus muscle of the eye (Function 10).
• Accessory (b): Controls neck and shoulder movements (Function 7).
• Facial (c): Involved in taste, salivation, and secretion of tears (Function 11).
• Glossopharyngeal (d): Associated with swallowing (Function 12).
• Hypoglossal (e): Controls tongue movements (Function 8).
• Oculomotor (f): Responsible for pupil constriction and eyelid opening (Function 5).
• Olfactory (g): Related to the sense of smell (Function 6).
• Optic (h): Concerned with vision (Function 9).
• Trigeminal (i): Transmits sensory impulses from teeth and face (Function 4).
• Trochlear (j): Stimulates the superior oblique muscle of the eye (Function 3).
• Vagus (k): Regulates heart rate (Function 1).
• Vestibulocochlear (l): Deals with equilibrium and hearing (Function 2).
