Mandible Flashcards
1. Identify the major external and internal features of the mandible 2. Identify the foramina of the mandible 3. Identify the craniometric landmarks of the mandible 4. Identify with how many other bones the mandible articulates
Only bone in the entire cranium that does not articulate with its adjacent skull bones via sutures.
Mandible
The mandible articulated with the neurocranium via the temporal bone at the ____
TMJ, Temporomandibular joint
All muscles of ____ connect to mandible
Mastication
Posterior projection part that connects the body of the mandible with the condylar process. Allows for insertion of the temporalis and masseter muscles
Ramus
Shark-fin shaped feature anterior to the mandibular notch
Coronoid Process
Bony extrusion which forms the lower bony component of the TMJ
Condylar Process
Houses the mandibular teeth and is continuous with the mandibular body
Alveolar Process
A hole on the mandibular body which lets a continuation of the inferior alveolar nerve out. Ounce it leaves this region, it is known as the mental nerve and innervates part of the chin
Mental Foramen
Separated the coronoid process from the condylar process
Mandibular notch
What are 2 features that are sexually dimorphic
Mental Protuberance (mental eminence) Mental tubercles
Landmark where the two halves of the mandible fused during development. Females tend to have a more prominent one than males
Mental protuberance (middle of butt chin)
In males, this projects more anteriorly to give men a square appearance to the front of the mandible
Mental tubercles (butt chin)
V3 of CN V (Inferior Alveolar Nerve) enters this hole on the internal surface of the mandible to innervate the mandibular teeth
Mandibular foramen
Where should you inject a patient to numb their mandibular teeth and chin?
V3 of CN V (Inferior Alveolar Nerve) located inside the mandibular foramen
A shark-fin shaped lip about the mandibular foramen which serves to protect the soft tissue structures entering the foramen
