Balance - they tell your brain which way up you are.
If you are refering to the ear. It is the Vestibule, Cochlea, and semi circular canal.
The function of semi circular canal in the ear is balance and orientation
Balance - they tell your brain which way up you are.
The inner ear translates sound into nerve impulses for the brain, and maintains the balance of the body. There are three main sections: - Cochlea: It is coiled portion and auditory portion of inner ear. It reacts to vibrations in various frequencies by sending neural impulses to the brain. The primary section is called the Organ of Corti, containing 15,000 to 20,000 nerve receptors. - Semi-circular canal: Three fluid filled canals horizontal semi-circular canal, posterior semi-circular canal and anterior semi-circular canal are called semi-circular canals. The fluid inside these canals is called endolymph. The dilation at one end of canal is called ampulla. Ampulla contains Cupula and hair cells. Semi-circular canals are responsible for body balance and detect direction of rotation of head. - Vestibule: It is located between the semi-circular canals and cochlea. Its anterior and inferior part has several minute holes for the passage of filaments of acoustic nerve (auditory nerve) to saccule. Saccule detects the motion of head when it moves vertically. At the upper and back of vestibule a structure called utricle detects the degree of tilt movement of head.
The inner ear consists of the bony labyrinth, a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: -- the cochlea, dedicated to hearing -- the vestibular system, dedicated to balance The cochlea transforms vibrations into nerve impulses for the brain. On the opposite side of the vestibule are the three semi-circular canals, which provide nerve signals on the motion of the body along 3 axes. There are otolithic structures in the vestibule (called the utricle and saccule) that provide information on the relative position of the head and body.

We find the structures for balance in the inner ear. They include, for dynamic equilibrium, the semi-circular canal, and for static equilibrium, the vestibule (which contains the utricle and saccule).
They are the organ of balance.
They are the sensory organs for balance.
