What is the spiral in the ear called?

the cochlea
Structure of the cochlea. The cochlea contains the sensory organ of hearing. It bears a striking resemblance to the shell of a snail and in fact takes its name from the Greek word for this object. The cochlea is a spiral tube that is coiled two and one-half turns around a hollow central pillar, the modiolus.

What is the fluid-filled structure in the inner ear?

The cochlea is the most critical component of the inner ear. It is divided into three fluid-filled chambers, called scalae, that spiral around a bony core. The scala media, or cochlear duct, contains the organ of Corti, which perceives sound.

How do you get rid of inner ear fluid?

In some cases, people need surgery for a blocked eustachian tube. The doctor makes a small cut in the eardrum to drain fluid and to make the pressure the same inside and outside the ear. Sometimes the doctor will put a small tube in the eardrum. The tube will fall out over time.

Why is the cochlea filled with fluid?

The cochlea has a dual use, it also is a balance organ. Plus the fluid in the cochlea is a necessity for moving the hair cells and triggering the electrical impulse necessary for hearing. Air alone, especially trapped in a pocket such a the Corti organ, would not be able to achieve this.

What is an endolymph?

Endolymph, also known as Scarpa fluid, is a clear fluid that can found in the membranous labyrinth of the inner ear. It is unique in composition compared to other extracellular fluids in the body due to its high potassium ion concentration (140 mEq/L) and low sodium ion concentration (15 mEq/L).

How do I get rid of fluid in my inner ear?

Typically, treatment is not necessary for fluid in the ears. 2 The fluid will usually drain on its own within a few weeks. However, if it does not, treatment will depend on several factors. If the fluid is present for 6 weeks, treatment may include a hearing test, a round of antibiotics, or further observation.

Which is part of the inner ear contains the spiral ganglion?

Rosenthal’s canal or the spiral canal of the cochlea is a section of the bony labyrinth of the inner ear that is approximately 30 mm long and makes 2¾ turns about the modiolus, the central axis of the cochlea that contains the spiral ganglion .

Why is the inner ear called the Labyrinth?

Inner ear: The inner ear, also called the labyrinth, operates the body’s sense of balance and contains the hearing organ. A bony casing houses a complex system of membranous cells. The inner ear is called the labyrinth because of its complex shape. There are two main sections within the inner ear: the bony labyrinth and the membranous labyrinth.

Where does the liquid of the inner ear come from?

The malleus articulates to incus which connects to the stapes. The footplate of the stapes connects to the oval window, the beginning of the inner ear. When the stapes presses on the oval window, it causes the perilymph, the liquid of the inner ear to move.

Where is the cochlea located in the ear?

The cochlea, the hearing organ, is located inside the inner ear. The snail-like cochlea is made up of three fluid-filled chambers that spiral around a bony core, which contains a central channel called the cochlear duct. Inside the cochlear duct is the main hearing organ, the spiral shaped organ of Corti.
