Which of the following nerve constitute the afferent component of corneal reflex?
| A |
Vagus nerve |
|
| B |
Facial nerve |
|
| C |
Trigeminal nerve |
|
| D |
Glossopharyngeal nerve |
The afferent component of corneal reflex is mediated by trigeminal nerve and efferent component is mediated by facial nerve which innervates the orbicularis oculi muscle. In this reflex, touching the cornea from the side while the subject looks forward evokes blinking.

|
| D |
Abducens nerve |
The anterior belly of the digastric muscle is innervated by the mandibular division of the trigeminal nerve.
- The inferior alveolar nerve which give rise to the mylohyoid nerve innervates the mylohyoid muscle.
| A |
Vagus nerve |
|
| B |
Glossopharyngeal nerve |
|
| C |
Trigeminal nerve |
|
| D |
Facial nerve |
The pure motor branches of mandibular division of trigeminal nerve:
- Masseteric nerve (masseter muscle)
- Deep temporal nerves (temporalis muscle)
- Pterygoid nerves (pterygoid muscles)
- Nerve of the tensor tympani muscle
- Nerve to the tensor veli palatini muscle
| A |
Foramen ovale |
|
| B |
Foramen lacerum |
|
| C |
Foramen magnum |
|
| D |
Foramen spinosum |
- Foramen lacerum transmits the internal carotid artery.
- Foramen magnum transmits the medulla and its membranes, the spinal accessory nerves, the vertebral arteries, and the anterior and posterior spinal arteries.
Which is the nucleus of Masseteric Reflex?

|
| B |
Spinal nucleus of trigeminal nerve |
|
| C |
Mesencephalic nucleus of trigeminal nerve |
|
| D |
Dorsal nucleus of vagus nerve |
The reflex arc of masseteric reflex involves two nuclei of the trigeminal nerve, namely, the mesencephalic nucleus and the motor nucleus of trigeminal nerve .
