What is the name of the joint where the mandible articulates with the skull?

The name of the joint where the mandible articulates with the skull is the TMJ, or Temporomandibular Joint. This joint is crucial for involuntary and voluntary movements of the jaw, such as chewing and speaking. It connects the temporal bone of the skull to the mandible, allowing for movement in multiple directions, including elevation, depression, and gliding.

The unique structure of the TMJ includes a disc made of fibrocartilage that assists in absorbing shock and providing a smooth movement, which is essential for the functions mentioned. Understanding the TMJ is vital for dental professionals since dysfunction of this joint can lead to pain and various dental issues.

The other options refer to different joints in the body that do not involve the mandible. For instance, the Glendale joint is not a recognized anatomical joint, while the sacroiliac joint connects the lower spine to the pelvis, and the atlantoaxial joint allows for rotation of the head. Each of these joints serves specific functions unrelated to the mandible's articulation with the skull, highlighting the importance of the TMJ in dental practice.
