Which bone of the head has a synovial joint?

Synovial joints, characterized by the presence of a synovial cavity filled with synovial fluid, are found in various parts of the body to facilitate smooth movement between bones. However, synovial joints are not typically found in the bones of the head. In the skull, the joints between most of the bones are fibrous joints, which allow for minimal movement and provide stability to the skull.

Here are some common types of joints and their locations in the skull:

  1. Sutures:
  • Sutures are fibrous joints found between the flat bones of the skull, such as the coronal, sagittal, lambdoid, and squamous sutures. They are immovable and provide structural integrity to the skull.
  1. Gomphosis:
  • Gomphosis is a specialized fibrous joint that holds the teeth in their sockets (alveoli) of the maxilla and mandible. It provides stability and support to the teeth.
  1. Syndesmosis:
  • Syndesmosis is a type of fibrous joint found in the distal tibiofibular joint, but it is not present in the skull.

While synovial joints are not typically found in the bones of the head, they are abundant in other parts of the body, such as the limbs, fingers, toes, and axial skeleton (e.g., vertebral column). Synovial joints allow for a wide range of movement and are essential for mobility and flexibility.
