Working on this study unit will enable you to:
- Identify the two main parts of the mandible.
- Name the bony features of the mandible.
The mandible is the largest bone of the human head. It is the only mobile bone of the skull (not including the auditory ossicles). The mandible is technically not part of the viscerocranium, however is sometimes still considered as such by some texts. It connects to the maxilla (part of the viscerocranium) via the teeth when the jaw is closed, and with the temporal bone (part of the neurocranium) via the temporomandibular joint. Due to its mobility, the prime function of the mandible is to assist in mastication.
This video tutorial will provide you with an overview of the mandible.
