What is the movable is the skull?
The Mandible is the only part of the skull that can move. But out of all these bones, only the mandible is movable. Moreover, the mandible or the jaw bone is one of the strongest and largest bones in the facial skeleton. The mandible forms the lower jaw and holds the lower teeth in place.
Is the only movable part of the skull?
There is only one movable joint in the skull. That is the joint connecting the lower jaw, or mandible, to the rest of the skull. All the other bones in the skull are firmly attached to one another by sutures.
What are the only movable bone of the head and face?
Mandible. The mandible forms the lower jaw and is the only moveable bone of the skull. At the time of birth, the mandible consists of paired right and left bones, but these fuse together during the first year to form the single U-shaped mandible of the adult skull.
Where are the sutures of the skull?
The major sutures of the skull include the following:
- Metopic suture. This extends from the top of the head down the middle of the forehead, toward the nose.
- Coronal suture. This extends from ear to ear.
- Sagittal suture.
- Lambdoid suture.
Which part of skull is movable and why?
Mandible is the largest, strongest and lowest bone found in the human face. It forms the lower jaw and also holds the roots of lower teeth in place. The mandible or lower jaw is the only movable part of the skull that takes part in formation of the temporomandibular joint with the temporal bone.
What is a suture line in the brain?
Cranial sutures are fibrous bands of tissue that connect the bones of the skull. The sutures or anatomical lines where the bony plates of the skull join together can be easily felt in the newborn infant. It is normal for infants to have these soft spots, which can be seen and felt on the top and back of the head.
What are the suture lines of the skull?
The “sutures” or anatomical lines where the bony plates of the skull join together can be easily felt in the newborn infant. The diamond shaped space on the top of the skull and the smaller space further to the back are often referred to as the “soft spot” in young infants.

Is the brain encased in the cranium?
The brain is encased in the cranium of the skull. The bones that make up the cranium are called the cranial bones. The remainder of the bones in the skull are the facial bones.
How are the flat bones of the skull sutured?
The mastoid process is a wide and rough projection that serves as another attachment point for neck muscles. While all the bones of the skull, other than the mandible, are sutured to one another, the flat bones of the cranium are visibly sutured where they articulate to another.
