match the names of the cranial nerves with their functions
a table shows the function and components of cranial nerve. the column headers are function and cranial nerve
controls muscles that move the eye and control the amount of light entering the eye (pupil size)
controls muscles of neck (trapezius and sternocleidomastoid)
sensory information for the sense of smell
controls muscles that move the tongue
controls muscles for swallowing and salivary glands. sensory information from carotid arteries

Explanation:

1. For the function "Controls muscles that move the eye and control the amount of light entering the eye (pupil size)", the cranial nerve is Oculomotor Nerve (III). It innervates eye muscles for movement and controls pupil size via parasympathetic fibers.
2. For "Controls muscles of neck (trapezius and sternocleidomastoid)", the cranial nerve is Accessory Nerve (XI). It controls these neck muscles.
3. For "Sensory information for the sense of smell", the cranial nerve is Olfactory Nerve (I). It is responsible for transmitting smell sensations.
4. For "Controls muscles that move the tongue", the cranial nerve is Hypoglossal Nerve (XII). It innervates tongue muscles for movement.
5. For "Controls muscles for swallowing and salivary glands, Sensory information from carotid arteries", the cranial nerve is Glossopharyngeal Nerve (IX). It has motor functions for swallowing/salivary glands and sensory from carotid arteries.

Answer:

1. Function: Controls muscles that move the eye and control the amount of light entering the eye (pupil size) → Cranial Nerve: Oculomotor Nerve (III)
2. Function: Controls muscles of neck (trapezius and sternocleidomastoid) → Cranial Nerve: Accessory Nerve (XI)
3. Function: Sensory information for the sense of smell → Cranial Nerve: Olfactory Nerve (I)
4. Function: Controls muscles that move the tongue → Cranial Nerve: Hypoglossal Nerve (XII)
5. Function: Controls muscles for swallowing and salivary glands, Sensory information from carotid arteries → Cranial Nerve: Glossopharyngeal Nerve (IX)
