Ear's nickname in ancient times
Onions or listeners.

Ear was called "window cage" in ancient times, "listener" in Six Books of Hejian, and "dragon onion" in plague. Ear is an auditory organ, where the qi of clearing yang passes, and it belongs to one of clearing orifices. Modern found that it has a balance function.

"Ling Shuweiqi" said: "Window cage, ears are also." The book of A-B says: "Those who have window cages have upper and lower veins in front of their ears, and those who press them by hand." I think it refers to the listening palace. Those protruding from both sides of the head and shaped like horns are called auricles. The periphery of the auricle is called the helix. Those protruding like a screen between the upper and lower incisors in front of the ear were called "shielding" in ancient times. The drooping part of the auricle is called the earlobe, which is called the ear bead in ancient times.

Composition of ears

1, auricle

There is a big hole outside the auricle, called the external auditory meatus, which communicates with the external auditory meatus. The auricle is funnel-shaped and has the function of collecting external sound waves. Most of them are supported by subcutaneous elastic cartilage, and the lower part only contains subcutaneous connective tissue and fat, which is called earlobe. Auricle is the clinical application site of auricular point therapy and auricular acupuncture anesthesia, and earlobe is the commonly used blood collection site in clinic.

2. External auditory canal

The external auditory canal is a curved tube from the hilum of the external ear to the tympanic membrane, about 2.5~3.5 cm long, and its skin continues from the auricle. The outer third of the external auditory canal wall is composed of cartilage, and the inner two thirds of the external auditory canal wall is composed of bone. There are ear hair, sebaceous glands and cerumen glands on the skin of cartilage.

3. Tympanic membrane

The tympanic membrane is a translucent membrane, which is shallow funnel-shaped, with the concave surface facing outward and the edge fixed on the bone. The external auditory canal and the middle ear are bounded by it. Sound waves coming through the external auditory canal will cause the eardrum to vibrate.

4. tympanic cavity

The tympanum is located between the tympanic membrane and the inner ear, and it is a small cavity containing gas with a volume of about 1 cm3. The tympanum is the main part of the middle ear, in which there are three ossicles: malleus, incus and stapes. The base plate of the stapes is attached to the oval window of the inner ear. These three ossicles are connected by ligaments and joints to form an ossicular chain. The vibration of the eardrum can be transmitted to the oval window through the ossicular chain, causing the vibration of lymph in the inner ear.

5. Inner ear

The inner ear, including vestibule, semicircular canal and cochlea, is composed of complex curved tubes, so it is also called lost. Labyrinth is full of lymph, vestibule and semicircular canal are the places where sensory receptors are located, which are related to the balance of the body.
