Appendicular Skeleton

The appendicular skeleton is responsible for facilitating movement and supporting the limbs, as well as providing attachment points for muscles.

The major bones include the humerus, radius, ulna, femur, tibia, fibula, scapula, clavicle, ilium, ischium, and pubis.

The humerus is the upper arm bone that connects the shoulder to the elbow, while the radius is one of the two bones in the forearm, located on the thumb side.

The ilium is commonly referred to as the 'hip bone'.

The ulna is the medial bone of the forearm, providing stability and forming the elbow joint with the humerus.

The pelvis is made up of the ilium, ischium, and pubis.

In the anatomical position, the radius is located laterally (on the thumb side) to the ulna.

The shoulder joint is a ball-and-socket joint, allowing for a wide range of motion.

The femur is the longest bone in the body, designed to support weight and facilitate movement in the leg.

The ischium provides support when sitting and forms part of the hip joint.
