The bones of the upper and lower limbs attach to the axial skeleton through the joint girdles.

Upper limbs

Consisting of arm, forearm, wrist and hand.

The arm has only one bone: the humeruswhich is an upper limb bone.

The forearm is composed of two bones: the radio which is a long bone and that forms with the ulna (ulna) the skeleton of the forearm. The ulna is also a long bone that is located on the inside of the forearm.

The hand is made up of the following bones: carpal bones, metacarpal bones, and finger bones. The carpal bones (consisting of eight bones arranged in two rows), are a portion of the skeleton that is located between the forearm and hand. The metacarpal is the portion of bones that is located between the carpus and the fingers.

Lower members

They are larger and more compact, adapted to support body weight and for walking and running. Consisting of thigh, leg, ankle and foot.

The thigh has only one bone - the femur - which articulates with the pelvis through the catiloid cavity. The femur has a large rounded head attached to the shaft by a narrow portion - the anatomical neck. The lower end of the femur has forward an articular portion - the trochlea - which brings two condyles apart by the inter-condylar chamfer. The femur is the largest of all bones in the skeleton.

The leg is composed of two bones: the tibia and the fibula (fibula). The tibia is the innermost bone and the fibula is the bone located next to the tibia.
The toes are articulated extensions that end in the feet. The foot is made up of bones tarsus, metatarsal and the bones of the fingers. The metatarsal is the part of the foot between the tarsus and the toes. The tarsus is the posterior bone portion of the foot skeleton.

Pelvic Waist

Also known as the pelvis, connects the lower limbs to the trunk. They can distinguish man from woman. In women it is wider, which represents adaptation to childbirth.
