Anatomy of the Mandible

The mandible, commonly referred to as the jawbone, is crucial for functions such as chewing and speaking.
The body of the mandible is its principal part, providing structural support.
The ramus is a vertical extension from the body, allowing muscle attachment and movement.
The mandibular foramen is located on the ramus; it allows passage for the inferior alveolar nerve and blood vessels, which are vital for sensation and blood supply to the lower jaw.
The coronoid process is a pointed protrusion at the top of the ramus, serving as an attachment for the temporalis muscle, important for elevating the jaw.
The condylar process is another crucial upper feature of the ramus that forms a joint with the temporal bone, enabling jaw movement.
The submandibular fossa is a depression found on the inner surface of the mandible, housing the submandibular gland.
The sublingual fossa lies anterior to the submandibular fossa and accommodates the sublingual gland.
The alveolar process contains sockets for teeth, providing stability and support during dental functions.
The mental foramen is an opening located on the anterior surface, which permits the passage of nerves and vessels that serve the chin and lower lip.
The mental protuberance is the noticeable bony prominence on the front of the mandible, forming the chin's shape.
