The ramus of the mandible is a vertical extension of the lower jawbone, known as the mandible. It connects the body of the mandible to the skull, playing a crucial role in jaw movement and function. The ramus has two main parts: the anterior coronoid process, which serves as an attachment point for muscles, and the posterior condylar process, which articulates with the temporal bone of the skull at the temporomandibular joint (TMJ). The ramus is important for various functions, including chewing and speaking. It provides structural support for the lower jaw and helps in the alignment of teeth. Any abnormalities or fractures in the ramus can lead to issues with jaw movement and discomfort, affecting overall oral health.
