In each of your ears, you have three half-circular tubes with a fluid called endolymph in them. They also contain little hairs (cilia) that can detect the motion of this fluid. Using these, the semicircular canals detect the motion of the head, to help with coordination and balance. When your head moves, the endolymph moves to different sections of the canals, hitting the cilia and sending the signal to the brain. The three canals are oriented in different directions, so the brain can tell which direction you're moving.

What part of the ear detects motion when you spin?
The semi-circular ear canal
What parts of the ear are in the inner ear?
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.
What are the names definitions and functions of the parts of the ear?
Outer earIt consists of Pinna, ear canal and ear drum. Pinna (also called auricle): It is outer most (and visible) portion of ear. Its external parts are wide while inner portion is narrow. Because of its shape it act as a funnel (collects the sound and directs it through ear canal to ear drum).Ear canal (auditory canal): It contains sebaceous glands which secrete ear wax (cerumen) for lubrication of ear.Ear drum (tympanic membrane): It is thin membrane located at the end of outer ear. It carries the sound towards middle ear.Middle earIt consists of three ear bones or ossicles (malleus, incus and stapes). These ossicles transmit sound to the inner ear. Malleus (also called hammer): It is hammer like ossicle. Its one end is attached to ear drum while other is connected with incus.Incus (anvil): It is anvil shaped bone, attached with malleus and stapes.Stapes: stirrup shaped bone attached to incus and oval window or vestibular window (membrane covered opening between middle ear and inner ear).Inner earIt contains cochlea, vestibule and semicircular canals. Cochlea: It is coiled portion and auditory portion of inner ear.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.
What part of the ear located the fluid that maintains the sense of balance?
Semi-Circular canals
What does semi circular canals in the ear do?
They are a type of motion sensor, as the movements of the cilia are communicated to the brain.
What part of the ear detects motion when you spin?
The semi-circular ear canal
What is the function of the semiciricular canals in the ear?
The function of semi circular canal in the ear is balance and orientation
What structures compose the bony labyrinth?
If you are refering to the ear. It is the Vestibule, Cochlea, and semi circular canal.
What part of the ear helps keep you balanced?
The semi-circular canal helps your balance of your body.

What is the receptor for dynamic balance in the ear?
The receptors for static equilibrium are located in the inner ear of humans.

There are otolithic structures in the vestibule (called the utricle and saccule) that provide information on the relative position of the head and body.
What part of the ear controls body balance?
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).
What is semi circular canal?
Balance - they tell your brain which way up you are.
What is the inner ear's job?
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.
