Which type of joint is characterized by slight movability, such as the spine or pubic bone?

The correct choice is characterized by joints that allow for slight movement, which is key in the context of areas like the spine or the pubic bone. Amphiarthrosis joints are specifically designed for limited mobility, providing flexibility while still offering stability.

For instance, in the spine, the intervertebral discs serve as amphiarthrotic joints, allowing for slight movements that facilitate bending and twisting while also supporting the structure of the spine. Similarly, the pubic symphysis connects the two sides of the pelvis for childbirth and walking, exemplifying the amphiarthrotic type's ability to contribute to movement as well as structural integrity.

Understanding amphiarthrosis is essential for recognizing the functional anatomy of the human body, particularly in regions where flexibility and strength are both necessary.
