Give the location of a ball and socket joint in a human body

Explanation

**Step-by-Step Solution:**

1. **Understanding Ball and Socket Joints**: Ball and socket joints are a type of synovial joint that allows for rotational movement in multiple directions. They consist of a spherical head (the ball) that fits into a rounded cavity (the socket).

2. **Identifying Locations**: In the human body, there are two primary locations where ball and socket joints are found:
- **Shoulder Joint**: This joint is formed between the humerus (the upper arm bone) and the pectoral girdle (the shoulder girdle). The head of the humerus fits into the glenoid cavity of the scapula (shoulder blade).
- **Hip Joint**: This joint is formed between the femur (the thigh bone) and the pelvic girdle. The head of the femur fits into the acetabulum of the pelvis.
