(Phys.org) —Within the mammalian inner ear, or cochlea, a remarkable but and long-debated phenomenon occurs: As they move from the base of the cochlea to its apex, traveling fluid waves – that is, surface waves, in which ...

A team of researchers affiliated with several institutions in the U.S. and Brazil has found evidence that pumpkin toadlets (Brachycephalus) have poor jumping skills because their inner ear canals are too small. In their paper ...
From the smooth tubes of our arteries and veins to the textured pockets of our internal organs, our bodies are made of tissues arranged in complex shapes that aid in performing specific functions.

An international team of researchers has found that an ancient crocodile relative underwent body transitions as it evolved from a land to a sea creature before its ears changed to suit an underwater environment. In their ...
The human ear, like those of other mammals, is so extraordinarily sensitive that it can detect sound-wave-induced vibrations of the eardrum that move by less than the width of an atom. Now, researchers at MIT have discovered ...

An international team of researchers has found that it is possible to use the human bony labyrinth of the ear as an indicator of dispersal from Africa. In their paper published in Proceedings of the National Academy of Sciences, ...
Scientists at the USC Dornsife College of Letters, Arts and Sciences have discovered an entirely new class of ion channels. These channels let protons (H+ ions) into cells, are important in the inner ear for balance, and ...

The ear is the organ that detects sound. It not only receives sound, but also aids in balance and body position. The ear is part of the auditory system.
The word "ear" may be used correctly to describe the entire organ or just the visible portion. In most mammals, the visible ear is a flap of tissue that is also called the pinna and is the first of many steps in hearing. In people, the pinna is often called the auricle. Vertebrates have a pair of ears, placed somewhat symmetrically on opposite sides of the head. This arrangement aids in the ability to localize sound sources.
