What are joints? Name them.

Joints are the places in the body where two or more bones meet. They allow movement and flexibility. At the joints, bones are held together by strong tissues called ligaments. There are different types of joints in the human body, including:

• Fixed joints (do not allow movement, e.g., skull)
• Ball and socket joints (allow movement in all directions)
• Hinge joints (allow movement in one direction, like knees and elbows)
• Pivotal joints (allow rotation, like neck)
• Gliding joints (allow bones to slide over each other)
