Temporal muscles, also known as the temporalis muscles, refer to a pair of muscles located on the side of the skull, specifically in the temporal region. These muscles play a crucial role in various aspects of jaw movement and are responsible for performing functions such as chewing and biting.
The temporal muscles originate from the temporal fossa, a depression on the side of the skull, and attach to the mandible (lower jawbone) via a tough fibrous tendon known as the temporalis tendon. When these muscles contract, they exert force on the mandible, facilitating movements such as closing the mouth, grinding food, and moving the jaw from side to side.
The temporal muscles derive their name from their location in the temporal region of the head. They are one of the key muscles involved in the mastication process and are therefore essential for efficient eating and digestion. Additionally, they contribute to facial aesthetics, helping to define the shape of the face.
In summary, the temporal muscles are bilateral muscles located in the temporal region of the skull. They play a vital role in jaw movement, contributing to activities such as chewing, biting, and grinding food. These muscles are a crucial part of the mastication process and also provide structural support to the face.
The etymology of the term "temporal muscles" can be traced back to the Latin language. The word "temporal" comes from the Latin word "temporalis", which means "of the temples". This refers to the area of the head where these muscles are located. The Latin word "temporalis" is derived from the noun "tempus", meaning "temporal" or "time". Thus, the "temporal muscles" are named after their location, specifically the temples, which lie on the sides of the skull adjacent to the eyes and temporal bone.
