How Much Do You Know About Appendicular Skeleton? Quiz

The scapula, commonly known as the shoulder blade, is a flat, triangular bone located on the back of the shoulder. It forms the posterior part of the shoulder girdle and provides attachment points for various muscles involved in shoulder movement.

The patella, or kneecap bone, is a flat, triangular bone located in front of the knee joint. It protects the knee joint and provides mechanical advantage to the quadriceps muscle by increasing the leverage during knee extension.

The clavicle, or collarbone, articulates with the scapula at the acromioclavicular joint and with the humerus at the sternoclavicular joint. It helps to stabilize the shoulder joint and allows for a wide range of arm movements, including elevation and rotation of the shoulder.

The humerus is the long bone of the upper arm that connects the shoulder girdle to the forearm bones. It articulates with the scapula at the shoulder joint and the radius and ulna at the elbow joint, allowing for a wide range of arm movements.

The forearm consists of two bones: the radius and ulna. The ulna is located on the medial side of the forearm and is longer and larger than the radius. It provides stability to the forearm and forms the elbow joint with the humerus.

The scapula, commonly known as the shoulder blade, is a flat, triangular bone located on the back of the shoulder. It forms the posterior part of the shoulder girdle and provides attachment points for various muscles involved in shoulder movement.

The carpal bones are located in the wrist, which is part of the hand region of the appendicular skeleton. These small, irregularly shaped bones form the wrist joint and allow for a wide range of movements necessary for hand function.

The pelvic girdle consists of three bones: the ilium, ischium, and pubis. The ilium and ischium are the largest and most prominent bones of the pelvic girdle, forming the hip bones that provide support and stability to the trunk and transfer body weight to the lower limbs.

The olecranon is a prominent bony projection at the proximal end of the ulna that forms the tip of the elbow. It serves as the attachment point for muscles and ligaments involved in elbow extension and provides protection to the underlying structures.

The calcaneus, or heel bone, is the largest of the tarsal bones located in the foot region of the appendicular skeleton. It forms the prominent posterior part of the foot and provides attachment points for various muscles involved in walking, running, and jumping.
