Helix (ear)

Helix (ear)

The Helix is the prominent rim of the auricle of the ear. The term "helix" is derived from the Ancient Greek word ἕλιξ, meaning "twisted, curved". The helix is made up of cartilage and skin and is located on the outer part of the ear. It starts just above the earlobe and continues upwards and backwards to the top of the ear.

Anatomy

The helix is the outermost part of the ear and is composed of a thin layer of skin and underlying cartilage. The skin is attached tightly to the cartilage and both are flexible, allowing the ear to bend and flex. The helix is the most prominent part of the auricle and is easily visible from the side. It forms a curved line that starts at the earlobe and continues upwards and backwards, ending at the top of the ear.

Etymology

The term "helix" comes from the Ancient Greek word ἕλιξ, which means "twisted, curved". This is a reference to the curved shape of the helix. The term was first used in this anatomical context by the Greek physician Hippocrates.
