- Shoulder girdles (4 bones) – Left and right clavicle (2) and scapula (2).
- Arms and forearms (6 bones) – Left and right humerus (2) (arm), ulna (2) and radius (2) (forearm).

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 appendicular skeleton includes the bones of the shoulder girdle, the upper limbs, the pelvic girdle, and the lower limbs.
Furthermore, what are the 126 bones of the appendicular skeleton? Appendicular Skeleton (126 bones)
Beside this, what does the appendicular skeleton consist of?
How many bones are there in human body?
The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. The bone mass in the skeleton reaches maximum density around age 21.
What is appendicular system?
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.
How many bones are in your skull?
The human skull is generally considered to consist of twenty–two bones—eight cranial bones and fourteen facial skeleton bones. In the neurocranium these are the occipital bone, two temporal bones, two parietal bones, the sphenoid, ethmoid and frontal bones.
What connects bone to bone?
“Ligament” most commonly refers to a band of dense regular connective tissue bundles made of collagenous fibers, with bundles protected by dense irregular connective tissue sheaths. Ligaments connect bones to other bones to form joints, while tendons connect bone to muscle.
What are the classification of bones?
The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones. They consist of a long shaft with two bulky ends or extremities. They are primarily compact bone but may have a large amount of spongy bone at the ends or extremities.
What are the types of bones?
There are five types of bones in the skeleton: flat, long, short, irregular, and sesamoid.
What does appendicular mean in medical terms?
: of or relating to an appendage: a : of or relating to a limb or limbs the appendicular skeleton.
What is the human skeleton made of?
The human skeleton consists of both fused and individual bones supported and supplemented by ligaments, tendons, muscles and cartilage. It serves as a scaffold which supports organs, anchors muscles, and protects organs such as the brain, lungs, heart and spinal cord.
How many bones are in the pectoral girdle?
The bones that attach each upper limb to the axial skeleton form the pectoral girdle (shoulder girdle). This consists of two bones, the scapula and clavicle (Figure 2). The clavicle (collarbone) is an S-shaped bone located on the anterior side of the shoulder.
What are the two types of skeleton?
Types of skeletons. There are two major types of skeletons: solid and fluid. Solid skeletons can be internal, called an endoskeleton, or external, called an exoskeleton, and may be further classified as pliant (elastic/movable) or rigid (hard/non-movable). Fluid skeletons are always internal.
What is the job of the appendicular skeleton?
The human 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). It also includes the pectoral (or shoulder) girdle and the pelvic girdle, which attach the upper and lower limbs to the body, respectively.
What is compact bone?
Compact bone, also known as cortical bone, is a denser material used to create much of the hard structure of the skeleton. The remainder of the bone is formed by cancellous or spongy bone. Compact bone is formed from a number of osteons, which are circular units of bone material and blood vessels.
What are the two major divisions of the appendicular skeleton?
The skeleton is subdivided into two major divisions—the axial and appendicular.
