Clavicles -- otherwise known as collarbones -- are thin bones that attach the shoulder blades to the breastbone. A break to a clavicle can occur as a result of a fall, a sports-related mishap or a car accident.

Adults have 206 bones. Babies are born with about 300 bones, but many fuse together as the baby grows. According to St.

The junction where two bones meet is a joint, also known as a bony articulation. With more than 200 bones in the human body, there are several different types of joints that give the body both mobility and stability. Joints are divided into three groups: freely movable, slightly movable, and immovable.

Each finger of the hand has three joints. If these joints become swollen it can cause discomfort. This swelling is an inflammation of the surrounding tissues and can be caused either by injury to the joint itself or, more commonly, by arthritis. Symptoms are pain, stiffness and loss of motion.

An ankle fracture can produce considerable loss of functional mobility. Once the fracture has healed, most physicians refer patients to physical therapy, which after removal of the cast is a vital step to full recovery.

There are 206 bones in the human body. They come in many shapes in sizes, molded generation after generation to articulate with one another providing support for the body. Bone is composed of hard dense tissue, blood vessels, and nerves. Bones anchor muscles and oppose muscle contractions allowing a limb to move.

Bone growth begins early in fetal development -- at a gestational age of approximately 6 to 7 weeks, according to the University of Maryland Medical Center -- and continues throughout the rest of your life.

Your bone density is directly correlated to your body fat, so if you're very slender or exercise too much, your bones may suffer. Girls and young women are susceptible to the "female athlete triad" – a combination of inadequate nutrition, hormone disruption and low bone density.

Methylsulfonylmethane, or MSM, is organic sulfur used by the body to grow bone, hair and nails. Drugs.com reports that MSM may be useful in elevating conditions such as arthritis or allergies. It is also used as a combatant against some parasitical infections.

The wrist is one of the smaller joints in your body, but it is made up of multiple bones. Two rows of 4 small carpal bones sit at the base of your hand. The bottom row of carpal bones meets the end of the forearm bones, enabling movement in your wrist joint.

Vitamins and minerals are essential nutrients for a person's growth and development. Because they need to be absorbed from the bloodstream to be effective, anything that hinders this process can result in your body getting insufficient nutrients.

In both the arms and the legs, the half closest to the body has one strong, thick, long bone. The other half of the arm or leg, the part farthest from the body, has two thinner bones. There are 206 bones in the entire human body, so the skeletal structure of the legs and arms are actually quite simple.
