Auricularis
Auricularis
Auricularis (pronunciation: aw-rik-yuh-lair-is) is a term used in anatomy to refer to a group of muscles surrounding the ear. The term is derived from the Latin word 'auricula', meaning 'ear'.
Etymology
The term 'Auricularis' is derived from the Latin 'auricula', which translates to 'ear'. This is in reference to the location of these muscles, which are found surrounding the ear.
Muscles
The Auricularis group of muscles consists of three muscles:
1. Auricularis Superior: This muscle is located above the ear and helps in moving the ear upwards.
2. Auricularis Anterior: This muscle is located in front of the ear and aids in moving the ear forward.
3. Auricularis Posterior: This muscle is located behind the ear and assists in pulling the ear backward.
Function
The primary function of the Auricularis muscles is to facilitate movement of the ear. While this function is not as pronounced in humans, it is more evident in many animals, which can move their ears to better capture sounds from different directions.
