Anatomía do Ollo

Eye Anatomy

• Structures of the eye (diagram): The eye is comprised of various parts. These include the cornea, iris, pupil, lens, retina, optic nerve, vitreous humor, sclera, choroid, and ciliary body.

• Cornea: A transparent, protective layer at the front of the eye.

• Iris: A colored muscle that controls the size of the pupil.

• Pupil: An opening in the center of the iris that regulates the amount of light entering the eye.

• Lens: Focuses light onto the retina.

• Retina: The light-sensitive layer at the back of the eye that contains photoreceptor cells (rods and cones) converting light to electrical signals.

• Optic Nerve: Carries visual information from the retina to the brain.

• Vitreous Humor: A clear gel that fills the space between the lens and the retina, maintaining the shape of the eye.

• Sclera: The white outer layer of the eye, providing structural support.

• Choroid: The middle layer of the eye, rich in blood vessels, nourishing the retina.

• Ciliary Body: Produces aqueous humor, which helps maintain eye pressure and nourishes the cornea and lens.

Orbital Bones

• Medial View: The bones around the eye's medial side, include the ethmoid, nasal, lacrimal, and part of the sphenoid bone.

• Superior View: Important bones include the frontal and parts of the ethmoid.

• Lateral View: Zygomatic, maxilla, and parts of the sphenoid bones.

• Inferior View: The maxilla, part of the sphenoid, and the palatine bones.

• Openings: Foramina for nerves and blood vessels are depicted on this illustration.

Eye Cross-Section

• Different layers of the eye: The illustration reveals the different structures and compartments.

Imaging (Cranial)

• Caldwell Projection: A radiographic technique for viewing the sinuses and facial bones in the region of the eye sockets.

• Waters Projection (Waters View): A radiographic technique for viewing the facial bones, particularly the orbits.

• Optic Nerve Projection: Imaging technique for the optic nerve.

Ear Anatomy

• Outer Ear: The visible portion extending to the eardrum(tympanic membrane).

• Middle Ear: The cavity housing the ossicles (malleus, incus, stapes) and connecting to the inner ear.

• Inner Ear: The innermost portion, including the cochlea (hearing) and semicircular canals (balance).

• Ossicles Are positioned in the middle ear.

• Cochlea: Part of the inner ear with fluid that sends signals about sound to the auditory nerve.

• Semicircular canals: Parts of the inner ear that detect head movements for balance and equilibrium.

• Eustachian Tube: Connects the middle ear to the pharynx.
