Articulation of femur with pelvic girdle is an example of:

Options

A. Gliding joint
B. Ball and socket joint
C. Hinge joint
D. Pivot joint

Answer

To determine the type of joint formed by the articulation of the femur with the pelvic girdle, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Bones Involved**: The question involves the femur (thigh bone) and the pelvic girdle.

2. **Understand the Joint Formation**: The femur articulates with the pelvic girdle at the acetabulum, which is a concave surface in the pelvic girdle.

3. **Determine the Type of Joint**:
- **Gliding Joint**: This type allows bones to slide over one another. Examples include joints between carpal bones. This does not apply here.
- **Ball and Socket Joint**: This joint consists of a spherical head (the head of the femur) fitting into a cup-like socket (the acetabulum of the pelvic girdle). This allows for a wide range of motion in multiple directions.
- **Hinge Joint**: This joint allows movement in one plane, like the elbow or knee. This does not apply here.
- **Pivot Joint**: This joint allows for rotational movement around a single axis, such as the joint between the first and second vertebrae. This does not apply here.

4. **Conclusion**: The articulation of the femur with the pelvic girdle is an example of a **ball and socket joint**.

### Final Answer:
The articulation of the femur with the pelvic girdle is an example of a **ball and socket joint**.
