Study Notes
Nerves of the Orbit
- The orbit receives nerve supply from various cranial nerves, including:
- Cranial Nerve II (Optic Nerve)
- Cranial Nerve III (Oculomotor Nerve)
- Cranial Nerve IV (Trochlear Nerve)
- Cranial Nerve VI (Abducens Nerve)
Oculomotor Nerve (Cranial Nerve III)
- Innervates several muscles within the orbit, controlling:
- Eye movements
- Positioning
- Supplies muscles such as:
- Superior rectus
- Inferior rectus
- Medial rectus
- Inferior oblique
- Contributes to:
- Vertical eye movements
- Horizontal eye movements
- Rotational eye movements
- Provides structural support and helps maintain the integrity of these vital structures
Optic Canal
- An important anatomical structure through which:
- The optic nerve passes
- The ophthalmic artery passes
- Connects the orbit to the cranial cavity
- Provides protection to these vital structures
