Canal

A tunnel through a bone.

Condyle

A rounded projection that articulates with another bone.

Facet

A flat articular surface that may form a joint with another facet or flat bone.

Fissures

A long narrow opening that allows for the passage of blood vessels or nerves.

Foramen

A round hole that allows for passage of blood vessels, nerves, muscles, or other structures.

Fossa

A shallow deep depression in a bone.

Margin

The edge of a bone.

Process

A raised area or projection on a bone.

Malleus

Also known as the hammer, one of the auditory ossicles.

Incus

Also known as the anvil, one of the auditory ossicles.

Stapes

Also known as the stirrup, one of the auditory ossicles.

Auditory Ossicles

Transfer vibrations to conduct sound to hearing receptors in the inner ear.

Thyroid Cartilage

A large cartilage of the larynx, known as the Adam's apple, which helps protect the vocal cords.

Cricoid Cartilage

A ring-shaped cartilage of the larynx located below the thyroid cartilage, providing support and structure to the airway.

Epiglottis

This leaf-shaped cartilage flap covers the windpipe during swallowing to prevent food and liquid from entering the lungs.

Arytenoid Cartilages

These pyramid-shaped cartilages sit on top of the cricoid cartilage and pivot to control the tension, position, and movement of the vocal cords.

Corniculate Cartilages

These tiny, horn-like cartilages sit on the peaks of the arytenoid cartilages to help support and reinforce the posterior part of the larynx.

Cuneiform Cartilages

These small, club-shaped cartilages are embedded within the aryepiglottic folds to provide structural support for the surrounding soft tissues and vocal folds.

Hyoid bone

In the front of the neck. Supports tongue and plays a key role in speaking and swallowing.
