The sternum, also known as the breastbone, is a flat bone located in the center of the chest. It connects to the ribs via cartilage and helps protect the heart and lungs.

The femur is the longest bone in the human body, located in the thigh. It connects the hip to the knee and supports the weight of the body during standing and walking.

The mandible, or lower jawbone, is the largest and strongest bone in the face. It holds the lower teeth in place and is the only movable bone of the skull.

The humerus is the bone of the upper arm or forelimb, extending from the shoulder to the elbow. It plays a crucial role in arm movement.

A ball and socket joint is a type of joint that allows for rotational movement in multiple directions. Examples include the shoulder and hip joints.

The scapula, or shoulder blade, is a flat triangular bone located in the upper back. It connects the humerus with the clavicle.

The clavicle, or collarbone, is a long bone that serves as a strut between the shoulder blade and the sternum, helping to stabilize the shoulder.

The radius is one of the two long bones in the forearm, located on the thumb side. It allows for the rotation of the wrist.

The ulna is the second of the two long bones in the forearm, located on the side opposite the thumb. It is longer than the radius and forms the elbow joint.

A hinge joint is a type of joint that allows movement in one plane, similar to the opening and closing of a door. Examples include the elbow and knee.
