What is the difference in function between the cochlea and the semicircular tubules?
The inner ear is entirely enclosed within the temporal bone. It has three separate regions: the cochlea, which is responsible for hearing and the vestibule and semicircular canals, which are responsible for balance and equilibrium.
What is the function of semicircular canal and cochlea?
Your semicircular canals are three tiny, fluid-filled tubes in your inner ear that help you keep your balance. When your head moves around, the liquid inside the semicircular canals sloshes around and moves the tiny hairs that line each canal.
Are the semicircular canals part of the cochlea?
inner ear. inner ear, also called labyrinth of the ear, part of the ear that contains organs of the senses of hearing and equilibrium. The bony labyrinth, a cavity in the temporal bone, is divided into three sections: the vestibule, the semicircular canals, and the cochlea.
What is the difference between semicircular canals and ducts?
The semicircular canals or semicircular ducts are three semicircular, interconnected tubes located in the innermost part of each ear, the inner ear. The three canals are the horizontal, superior and posterior semicircular canals….

What is the function of the cochlea in the ear?
The cochlea is a hollow, spiral-shaped bone found in the inner ear that plays a key role in the sense of hearing and participates in the process of auditory transduction. Sound waves are transduced into electrical impulses that the brain can interpret as individual frequencies of sound.
What is the difference between hearing and equilibrium?
Receptors for two sensory modalities (hearing and equilibrium) are housed in the ear. The external ear, the middle ear, and the cochlea of the inner ear are involved with hearing. The semicircular canals, the utricle, and the saccule of the inner ear are involved with equilibrium.
What is cochlea function?
What is the cochlea in the ear?
The hearing part of the inner ear is rolled up into a spiral called the cochlea, as it looks like a snail shell (‘cochlea’ is the greek word for snail). Note. Over the cochlea we can see the vestibule, which is the second sensory organ of the inner ear. It plays a main role in the equilibrium.
Where is the cochlear?
the inner ear
Location. The cochlea is one of two main structures that make up the inner ear. The inner ear is located behind the eardrum and next to the middle ear. The other structures are called the semicircular canals which are responsible for balance while the cochlea is involved in hearing.
What is the fluid in the cochlea called?
The cochlear duct forms a shelf across the cochlea dividing it into two sections, the scala vestibuli and the scala tympani. The entire inner ear is bathed in a cushioning fluid, called the endolymph when it lies within the membranous labyrinth and the perilymph when it separates the bony and membranous labyrinths.
Does cochlea help with balance?
How does the ear affect balance? The inner ear is composed of two parts: the cochlea for hearing and the vestibular system for balance. The vestibular system is made up of a network of looped tubes, three in each ear, called the semicircular canals.
What are the three canals inside the cochlea?
Anatomy. The spiral shape of the cochlea is necessary for the transduction of different sound frequencies.
What is the function of the semicircular canals?
The semicircular canals of the inner ear help you with balance. This movement of the fluid moves the hairs of the canals, creating nerve impulses that travel up to your brain and let it know that your head is off balance. You don’t fall over because your brain tells your muscles to support you.
What are semicircular canals function in balance or equilibrium?
– Lack of clear vision during rapid head movement – Reading – Writing – Fine motor control – Gross motor control
Where are the semicircular canals located in your body?
The semicircular canals or semicircular ducts are three semicircular, interconnected tubes located in the innermost part of each ear, the inner ear. The three canals are the horizontal, superior and posterior semicircular canals. The semicircular canals are a component of the bony labyrinth that are at right angles from each other.
