Question

What is the posterior border of the ramus pressure point?

1) Mandibular foramen
2) Mental foramen
3) Lingula
4) Coronoid process

Answer 1

The posterior border of the ramus can include the Mandibular foramen, Mental foramen, Lingula, and Coronoid process.

Step-by-step explanation:

The posterior border of the ramus refers to the back edge or margin of the mandibular ramus, which is the angled part of the lower jawbone. The options given are the structures that can be found along the posterior border of the ramus:

1. Mandibular foramen: This opening is located on the medial side of the ramus and allows the entry of sensory nerves and blood vessels that supply the lower teeth.
2. Mental foramen: These openings are located on each side of the anterior-lateral mandible and serve as exit sites for a sensory nerve that supplies the chin.
3. Lingula: This small flap of bone is located immediately next to the mandibular foramen, on the medial side of the ramus, and is anchored by a ligament that helps with the movement of the mandible.
4. Coronoid process: This flattened upward projection is located at the anterior margin of the mandibular ramus and serves as an attachment site for one of the biting muscles.
