Major Bones Of The Appendicular Skeleton Upper Limb

The skull vertebral or spinal column also known as the backbone or spine breastbone or sternum and ribs are a major division of the skeleton.

Major bones of the appendicular skeleton upper limb. The appendicular skeleton is comprised of 126 bones that are found in the upper and lower limbs and the pectoral and pelvic girdles. Although the bones of the upper and lower limbs differ in their functions and mobility they have the same fundamental plan each limb is composed of three major. Let s take a look at the bones of the appendicular skeleton. This consists of two bones the scapula and clavicle figure 6 41.

And the hand which is located distal to the wrist there are 30 bones in each upper limb see chapter 8 1 figure 1 the humerus is the single bone of the upper arm and the ulna medially and the radius laterally are. The appendicular skeleton is composed of the bones of the upper limbs which function to grasp and manipulate objects and the lower limbs which permit locomotion. The appendicular skeleton is composed of the 126 bones of the appendages and the pectoral and pelvic girdles which attach the limbs to the axial skeleton. The upper limb is divided into three regions.

The bones of the appendicular skeleton enable the body to move. Like the upper limb the lower limb is divided into three regions. These are the femur patella tibia fibula tarsal bones metatarsal bones and phalanges. The bones of the appendicular skeleton make up the rest of the skeleton and are so called because they are appendages of the axial skeleton.

The leg is specifically the region between the knee joint and the ankle joint. The appendicular skeleton is the portion of the skeleton of vertebrates consisting of the bones that support the appendages the appendicular skeleton includes the skeletal elements within the limbs as well as supporting shoulder girdle pectoral and pelvic girdle. Distal to the ankle is the foot the lower limb contains 30 bones. These consist of the arm located between the shoulder and elbow joints.

The bones that attach each upper limb to the axial skeleton form the pectoral girdle shoulder girdle. The thigh is that portion of the lower limb located between the hip joint and knee joint. The appendicular skeleton includes the bones of the upper and lower limbs extremities. Together these bones form the vertical axis of the body the axial skeleton.

It also includes the pectoral girdle or shoulder girdle that attaches the upper limbs to the body and the pelvic girdle that attaches the lower limbs to the body figure 1. The forearm which is between the elbow and wrist joints.
