Key Parts of the Eye

Eyelid (das Augenlid)

The eyelid protects the eye and keeps it moist by spreading tears over the surface.

Eyelash (die Wimper)

Eyelashes help to protect the eyes from debris and dust.

Eyebrow (die Augenbraue)

Eyebrows prevent sweat and other particles from falling into the eyes.

Iris (die Iris)

The iris is the colored part of the eye that controls the size of the pupil and, therefore, the amount of light that enters the eye.

Pupil (die Pupille)

The pupil is the black circle in the center of the eye, which expands and contracts to control the amount of light reaching the retina.

Cornea (die Hornhaut)

The cornea is the clear, dome-shaped surface that covers the front of the eye and helps to focus incoming light.

Retina (die Netzhaut)

The retina is the layer of cells at the back of the eye that senses light and sends images to the brain.

Lens (die Linse)

The lens is located behind the pupil and helps to focus light and images on the retina.

Sclera (die Lederhaut)

The sclera is the white outer layer of the eyeball, providing structure and protection.

Optic Nerve (der Sehnerv)

The optic nerve transmits visual information from the retina to the brain.

Tear Duct (der Tränenkanal)

The tear duct drains tears from the eye into the nasal cavity.

Anatomy of the Eye and Orbit: A Beginners Guide

The eyes are crucial for our daily lives, providing about 70% of the information we perceive. They are located in the orbits, which are bony cavities in the upper face. The orbits not only house the eyes but also contain several structures that support and protect them, including muscles, blood vessels, nerves, and glands. This guide will help you understand the basic anatomy of the eye and orbit.

Key Facts About the Orbit and Eyes

Orbit Definition

The orbit is a bony cavity within the skull that houses the eye and its associated structures, such as the muscles of the eye, eyelid, periorbital fat, and lacrimal apparatus.

Bones of the Orbit

The orbit is composed of the following bones:

• Maxilla
• Zygomatic bone
• Frontal bone
• Ethmoid bone
• Lacrimal bone
• Sphenoid bone
• Palatine bone

Structure of the Eye

The eye consists of several key structures:

• Cornea: The clear, dome-shaped surface that covers the front of the eye.
• Anterior Chamber: The fluid-filled space between the cornea and the iris.
• Lens: Focuses light onto the retina.
• Vitreous Chamber: The large, gel-filled cavity behind the lens.
• Retina: The light-sensitive layer at the back of the eye.

Muscles of the Eye

There are two main groups of eye muscles:

Extrinsic Muscles: These muscles control eye movement and include:

• Superior rectus
• Inferior rectus
• Medial rectus
• Lateral rectus
• Superior oblique
• Inferior oblique
• Levator palpebrae superioris (lifts the upper eyelid)

Intrinsic Muscles: These muscles control the iris and lens and include:

• Sphincter pupillae (constricts the pupil)
• Dilator pupillae (dilates the pupil)
• Ciliaris (controls the shape of the lens)

Innervation of the Eye

• Vision: The optic nerve (CN II) is responsible for transmitting visual information from the retina to the brain.
• Muscles: The oculomotor nerve (CN III), trochlear nerve (CN IV), and abducens nerve (CN VI) innervate the muscles that control eye movement.

Blood Supply of the Eye

• The blood supply to the eye is primarily provided by the ophthalmic artery. The vorticose veins are responsible for venous drainage.
