SUBMAXILLA Meaning and
Definition
-
Submaxilla refers to the lower jaw or mandible in vertebrates, particularly in mammals. It is a bone located inferior to the maxilla, forming the lower boundary of the mouth and holding the lower teeth. In humans, the submaxilla is a U-shaped bone that articulates with the skull at the temporomandibular joint. It plays a crucial role in various functions, such as chewing, speaking, and supporting the lower face.
The submaxilla is a compact and sturdy bone that provides structural support and protection to the oral cavity. It consists of two symmetrical halves (right and left) connected at the midline by a fibrous joint called the symphysis menti. Each half contains a horizontal part known as the body and two vertical extensions called rami. These rami serve as attachments for various muscles involved in jaw movement and facial expression.
Within the submaxilla, there are sockets for the teeth, known as dental alveoli, which hold the roots of the lower teeth firmly in place. The submaxilla also contains openings for nerves and blood vessels to pass through, ensuring the necessary supply of sensory and nutrient-rich blood to the lower face region.
In summary, the submaxilla refers to the lower jaw bone, forming the framework for the lower teeth and supporting the lower face in vertebrates, including humans.
