What is the ramus of the mandible?

  1. Horizontal portion of the mandible

  2. Vertical portion of the mandible

  3. Joint connection of the jaw

  4. Part of the skull that supports the teeth

The correct answer is: Vertical portion of the mandible

The ramus of the mandible refers specifically to the vertical portion of the mandible, which is the lower jawbone. This part extends upward from the body of the mandible and is crucial as it provides attachment points for muscles involved in mastication (chewing) and supports the temporomandibular joint (TMJ). Additionally, the ramus plays a significant role in the overall structure of the jaw, serving to connect the lower jaw to the skull and facilitating movement during the opening and closing of the mouth. Understanding this anatomical feature is important for dental professionals as it relates to various functions and potential issues within the jaw.
