What are the outer parts of the ear?

The outer ear consists of the visible portion on the side of the head, known as the pinna [1], and the external auditory canal (ear canal) [2]. The purpose of the pinna is to catch sound waves, amplify them slightly, and funnel them down the ear canal to the tympanic membrane (eardrum) [3].

What’s the top part of your ear called?

The outer ear is called the pinna and is made of ridged cartilage covered by skin. Sound funnels through the pinna into the external auditory canal, a short tube that ends at the eardrum (tympanic membrane).

What are the 5 parts of the ear?

The parts of the ear include:

• External or outer ear, consisting of: Pinna or auricle. This is the outside part of the ear.
• Tympanic membrane (eardrum). The tympanic membrane divides the external ear from the middle ear.
• Middle ear (tympanic cavity), consisting of: Ossicles.
• Inner ear, consisting of: Cochlea.

What are the parts of outer ear?

There are three different parts to the outer ear; the tragus, helix and the lobule. The ear canal starts at the outer ear and ends at the ear drum.

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).
