Flat bones are located within the skull (occipital nasal, frontal, nasal, lacrimal (and vomer) and the lung (sternum ribs) and pelvis (ilium ischium, pubis). Flat bones guard internal organs including the heart and brain. They can be smooth and serve as a shield. But, they can also offer large areas of attachment for muscles.
The femur, the longest bone you have and smaller bones in your fingers are both long bones. Long bones permit greater movement and support the body's overall weight. Long bones are located in the appendicular as well as lower limbs (the hip, radius, ulna or metacarpals) and also in the bones in the upper legs.
Bone shapes and structures that are irregular differ, and therefore they do not belong in any other category (flats shorts, shorts sesamoids, etc.). Because they are often complex, it helps to protect internal organs. For instance, the spine is protected by the vertebrae which are bones that are not normal that are found in the vertebrae column. The bones that are irregular in the pelvis (pubis the ilium, pubis, and the ischium) protect organs in the pelvic cavity.
Sesamoid bone is a type of bone that is embedded in the tendons. The small bones are commonly found in the muscles of the knees, hands, and feet. They protect the tendons from wear and stress. A sesamoid is a patella, which is commonly known as the kneecap.
Overview
While often thought of as a static structure the skeletal system actually is a Read More dynamic organ with numerous functions, such as shaping our human body, allowing locomotion and motor function, as well as facilitating respiration as well as protecting organs that are vital, producing marrow-derived cells, and playing a crucial role in homeostasis.
Bones are dynamic structures that, are always changing and remodeling in response the ever-changing world. In fact, there is so much change that within 4 years the bones of a child will be completely Read More new compared with their skeleton today
