coronoidprocessen

The coronoid process is a triangular eminence that projects from the anterior border of the ramus of the mandible. It serves as an important anatomical landmark and provides an attachment point for a significant muscle of mastication.

Specifically, the coronoid process is the insertion site for the temporalis muscle. This muscle originates from the temporal fossa and plays a crucial role in elevating the mandible, thus closing the jaw. The broad, flat surface of the coronoid process allows for a wide area of attachment, contributing to the powerful action of the temporalis.

The shape and size of the coronoid process can vary between individuals and can be influenced by factors such as genetics and the development of the masticatory muscles. In some cases, the coronoid process can be elongated or hook-shaped. Anatomical variations in the coronoid process can sometimes be relevant in surgical procedures involving the mandible or in the study of temporomandibular joint disorders. Its position relative to the mandibular notch is also a key anatomical consideration.
