What is the meaning of Ramus?
Ramus is widely used term in Dental Anatomy.
Ramus, in dental anatomy, refers to the major part of the mandible (lower jaw) or maxilla (upper jaw) that extends upwards from the body of the jawbone. The ramus branches off from the body of the jaw at the angle area, forming an angle known as the mandibular angle. It is an important anatomical structure as it serves as the site of attachment for various muscles involved in chewing and jaw movement.
The ramus of the mandible provides support and stability to the jawbone, allowing for the effective transmission of forces generated during mastication (chewing). It houses the temporomandibular joint (TMJ), which is responsible for the hinge-like movement of the jaw. Additionally, the ramus contains the openings for the inferior alveolar nerve and blood vessels, which supply sensation and blood to the lower teeth and surrounding structures.
In summary, the ramus is the elevated part of the jawbone that connects to the body of the mandible or maxilla. It plays a crucial role in mastication, jaw movement, and provides attachment sites for muscles involved in these functions.
