Yes. My older sister broke her arm when she was about 2 (i think? i wasn't born until she was 7). Her arm was broken in 6 places and never healed to become a normal human arm, so she now has 6 extra bones totaling 212 bones. I heard about this story recently and i have also become interested in humans with more than the average amount of bones, but i can't find any results.

The pelvis is above the femur,

Fat is stored in all bones that consist of yellow bone marrow.

It could be 1 of many things wrong. Although if you realized this pain after exercising, it more than likely is a pulled muscle that will heal on it's own. Go see a dr if the pain is severe & OTH meds do not work, a dr will more than likely prescribe muscle relaxants.

The Foramen Magnum

The entire group of bones that make up the head is called the skull and it too can be divided into two primary groups: the Cranium and the Facial area.

There are eight bones that make up the cranium, and six bones make up the facial area. In addition to the previous bones, there are six tiny bones (three pairs) called ossicles that are located in the ears. There is one final bone of the human skull. It is a single U-shaped bone to which the tongue attaches to and it is called the hyoid bone. That makes a total of 21.

The fibula is the smaller of the two long bones in the lower legs that is on the outer or lateral aspect on either leg.

Babies are born with 270 bones; however, they have more cartilage than bone. By adulthood, the number of bones has decreased to 206.

Conteledge. I think or its marrow?

the skull, pelvis, ribs, and scapula

what is an ishango bone

False ribs are connected via costal cartilage

There are twelve pair of ribs. The first seven ribs are true ribs because they have direct attachment to the sternum. An additional three pair of ribs have indirect attachment to the sternum meaning that they attach to other structures that attach to the sternum. The last two ribs are called floating ribs because they do not attach to the sternum at all. Because the floating ribs do not attach to the sternum they are prone to injury.

• The outer surface of bone is called the periosteum (say: pare-ee-os-tee-um). It's a thin, dense membrane that contains nerves and blood vessels that nourish the bone.
• The next layer is made up of compact bone. This part is smooth and very hard. It's the part you see when you look at a skeleton.
• Within the compact bone are many layers of cancellous(say: kan-sell-us) bone, which looks a bit like a sponge. Cancellous bone is not quite as hard as compact bone, but it is still very strong.
• In many bones, the cancellous bone protects the innermost part of the bone, the bone marrow (say: mair-oh). Bone marrow is sort of like a thick jelly, and its job is to make blood cells

Cartilage actually covers all surfaces of bones but the articular ends have an additional form that is metabolically quite active in that it contains multiple cell types all with differing functions. Some of these cells produce a portion of the joint-lubricating synovial fluid, while others are merely structural and protective of the underlying osteoblasts lengthening bones by building on to the epiphysis (growing end). The type of cartilage covering the diaphysis (shaft) of the bones is referred to as the periosteum and whenever this membrane is damaged (skateboarder hitting a tree stump, for example) the resulting injury is termed 'bone bruise' and may lead to serious complications such as osteonecrosis. On the other hand, severe damage to the cartilaginous end plates of the epiphysis can result in death of the growth zone and a failure to elongate as maturation proceeds.

The appendicular skeleton includes the bones of the limbs and the girdles that attach them to the axial skeleton. This comprises the shoulder girdle (clavicle and scapula), the bones of the arms (humerus, radius, and ulna), the bones of the hands (carpals, metacarpals, and phalanges), the pelvic girdle (hip bones), and the bones of the legs (femur, tibia, fibula, and the bones of the feet). Essentially, any bone associated with the limbs and their connections to the body is part of the appendicular skeleton.

The lower jaw, or mandible, is movable due to its connection to the skull via the temporomandibular joint (TMJ), which allows for a range of motion needed for activities like chewing and speaking. In contrast, the upper jaw, or maxilla, is fixed and forms part of the skull, providing structural support and stability. This design allows the lower jaw to articulate effectively with the upper jaw while maintaining the integrity of the facial structure.

They may result from trauma, such as when a driver's chest is forced into the steering column of a car in a car accident. A fracture of the sternum is usually a comminuted fracture. The most common site of sternal fractures is at the sternal angle. Some studies reveal that repeated punches or continual beatings, sometimes called "sternum punches", to the sternum area have also caused fractured sternums. Those are known to have occurred in contact sports such as rugby and football. Sternum fractures are frequently associated with underlying injuries such as pulmonary contusions, or bruised lung tissue.
