The outer ear is unique to mammals, but its evolutionary origin has remained a mystery. According to a study published in Nature from the USC Stem Cell lab of Gage Crump, this intricate coil of ...

A recent study has uncovered the surprising evolutionary origin of the mammalian outer ear, linking it to the gills of ancient fish and marine invertebrates. The research reveals that both structures ...

Perichondritis is an infection that occurs in the tissue of the cartilage located in your outer ear, which is called the auricle or pinna. The infection itself is sometimes referred to as auricular ...

Early symptoms of relapsing polychondritis include sudden pain in cartilage, ear swelling, joint inflammation, and eye problems. Although polychondritis is not currently curable, treatment helps ...

Most of the cells in your body have an internal "skeleton" that maintains the shape of the cell. Several types of relatively stiff large molecules normally make up the so called cytoskeleton. These ...

The three types of hearing loss are sensorineural, conductive, and mixed hearing loss. They each involve different parts of the ear and may have varying causes and treatments. Hearing loss in one or ...

Evolution is a master recycler. It often uses old structures (or ancient genes) for new jobs. The mammalian ear is a perfect example. Over the eons, the jawbones of our fish ancestors became three ...
