The ears are funnel-shaped. The role of the ear is to collect sound waves from the outside world. The outermost part of the ear is called the ear chakra, which corresponds to the opposite ear chakra, and between the ear chakra and the opposite ear chakra is the navicular fossa. The navicular fossa has a depression forward called the triangular fossa, next to which is the foot of the ear chakra. The part of the ear that extends downward is attached to the face with the ear screen, and opposite to the ear screen is the pair of ear screens. Inside the auricle is a large depression called the auricular cavity, which contains very important structural parts and is prone to pigmented nevi, auricular pseudocysts, and other related diseases. The auricle is connected to the external auricular opening by a depression called the external auricular opening. At the bottom of the auricle is the earlobe, which is made up of a large amount of rich fatty tissue.
