The term "parotid notch" refers to a small depression located at the base of the auricle of the ear. Phonetically, the word is spelled /pəˈrɒtɪd nɒtʃ/, with stress on the first syllable. The "p" is pronounced with a puff of air, while the following "a" is pronounced with an open sound like the "a" in "cat." The "o" in "notch" is pronounced as a short vowel sound and the "ch" is pronounced as a voiceless postalveolar affricate.
The term "parotid notch" refers to a specific anatomical feature located near the back of the lower jaw in mammals, including humans. It designates a small concave indentation or depression found on the upper border of the mandible, more precisely on each side of the ramus of the mandible.
Within the parotid notch, one can observe the presence of the parotid gland, which is the largest salivary gland in the human body. This gland is responsible for producing and secreting saliva, playing a critical role in the digestive process by moistening food and beginning the breakdown of complex carbohydrates.
The parotid notch is significant for several reasons. Firstly, it serves as a passage or opening where the parotid duct, also known as Stensen's duct, emerges. This duct transports saliva from the parotid gland to the mouth cavity, allowing for the controlled release of saliva during chewing and swallowing.
Furthermore, the parotid notch provides a point of reference for medical and dental professionals. It aids in locating and diagnosing problems related to the parotid gland, such as swelling, infection, or the formation of tumors. Additionally, it is a crucial landmark during surgeries involving the mandible or the parotid gland, ensuring precision and accuracy during procedures.
Overall, the parotid notch is a distinctive anatomical feature associated with the parotid gland and plays a vital role in salivary gland function, dental health, and medical procedures.

The word "parotid" originates from the Latin word "parotis", referring to the parotid gland, which is the largest salivary gland located near the ear. The term "parotid" itself stems from the Greek word "parotis", meaning "swelling near the ear".
The word "notch", on the other hand, comes from the Middle English word "noche", which is derived from Old French "noche" or "noke". This ultimately traces back to the Latin word "nocca", meaning "knuckle" or "joint". In anatomical terms, "notch" refers to a small indentation or recess in a bone or other structure.
Therefore, the term "parotid notch" describes a small indentation or gap near the parotid gland.
