pinna

Examples of pinna in the following topics:

• Audition: Hearing, the Ear, and Sound Localization

  • It includes the pinna, the ear canal, and the most superficial layer of the ear drum, the tympanic membrane.
  • The pinna, the fold of cartilage that surrounds the ear canal, reflects and attenuates sound waves, which helps the brain determine the location of the sound.
  • Sound reception occurs at the ears, where the pinna collects, reflects, attenuates, or amplifies sound waves.

• Types of Leaf Forms

  • The pinnules on one secondary vein are called "pinna".

• Reception of Sound

  • In mammals, sound waves are collected by the external, cartilaginous outer part of the ear called the pinna.

• Human Perception of Sound

  • When you look at someone's ear, you are really only seeing the pinna, the outer most portion of the ear.

• Structure, Type, and Location of Cartilage

  • Elastic cartilage is found in the epiglottis (part of the larynx) and the pinnae (the external ear flaps of many mammals, including humans).
