Study Notes

Sternum

The sternum is a flat bone composed of three parts: the manubrium sterni, the body of the sternum, and the xiphoid process.
The manubrium is wider at the top and narrows towards the bottom.

Sphenoidal Sinuses

The two sphenoidal sinuses are located within the body of the sphenoid bone.
Each sinus opens into the sphenoethmoidal recess, which is above the superior concha.

Laryngeal Folds

The vestibular fold is a fixed fold on each side of the larynx.
It is formed by mucous membrane covering the vestibular ligament and is vascular and pink in color.
In children, the narrowest part of the larynx is within the cricoid cartilage.
