Arytenoid cartilage are Either of a pair of cartilages at the back of the larynx, used in the production of different kinds of voice quality (for example, creaky voice).

Tall narrow cells ar not the part of respiratory epithelium.

The visceral pleura is the delicate serous membrane that covers the surface of each lung (the lung parenchyma) and dips into the fissures between the lobes.
