Vestibule (architecture)

A vestibule is an anteroom (antechamber) or small foyer leading into a larger space, such as a lobby, entrance hall, passage, etc., for the purpose of waiting, withholding the larger space view, reducing heat loss, providing space for outdoor clothing, etc. The term applies to structures in both modern and historical architecture since ancient times. In modern architecture, vestibule typically refers to a small room next to the outer door and connecting it with the interior of the building. In ancient Roman architecture, vestibule referred to a partially enclosed area between the interior of the house and the street.

Vestibule (ear)

The vestibule is the central part of the bony labyrinth in the inner ear, and is situated medial to the eardrum (tympanic cavity), behind the cochlea, and in front of the three semicircular canals. The vestibule contains two sacs: the utricle and the saccule, which respond to gravity and linear acceleration. Because of their function in the sense of balance, the vestibule and the semicircular canals together are often referred to as the vestibular system.

Vestibule (mouth)

In oral anatomy, the vestibule is the area between the teeth, lips and cheeks. It is divided into two sections: the labial vestibule (in front of the lips), and the buccal vestibule (in front of the cheeks).

Vestibule (nose)

The vestibule is the most anterior part of the nasal cavity and is surrounded by the alae nasi. It is lined by skin containing sebaceous glands and is continuous with the skin of the face.

Vestibule (vagina)

The vestibule of the vagina is a part of the vulva between the labia minora into which the urethral opening and the vaginal opening open. Its edge is marked by Hart's line. It represents the distal limit of the urogenital sinus of the embryo.

Vestibule (train)

A vestibule is an enclosed area at the end of a passenger car on a train. The vestibule prevents the escape of heat from the car when the end door is opened, and also serves as a safety measure to prevent passengers from falling out of the moving train.

Vestibule (ship)

On a ship, a vestibule is a compartment used for entry into the ship itself. It is typically located at the end of the gangway and is often equipped with doors or gates to prevent unauthorized access to the ship.
