Noun: - A branch or branchlike structure: In anatomy and biology, a "ramus" refers to a slender, projecting part or branch, particularly one that is part of a forked structure or a branching system, such as in bones, nerves, or blood vessels. - Specifically, the vertical posterior part of the mandible: In human anatomy, the "ramus" (often "mandibular ramus") is the broad, vertical, posterior part of the lower jawbone (mandible) that connects the body of the jaw to the skull via the temporomandibular joint.
