Name the following:
Part of the skeleton with almost all immovable joints.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a specific part of the skeleton that contains almost all immovable joints.

2. **Identifying Immovable Joints**: Immovable joints are joints that do not allow any movement. In the human body, these types of joints are primarily found in the skull.

3. **Analyzing the Skull**: The skull is made up of several bones that are fused together, creating a rigid structure. Most of these bones are immovable, meaning they do not allow for any movement between them.

4. **Noting the Exception**: The only exception in the skull is the lower jaw (mandible), which is a movable joint. All other bones in the skull are fixed and do not move.

5. **Conclusion**: Based on this analysis, the part of the skeleton with almost all immovable joints is the "Skull."

**Final Answer**: Skull
