Click to View Larger Image Microscopic Structure of Bones. The skeleton makes up about 30-40% of an adult's body mass. The skeleton's mass is made up of nonliving bone matrix and many tiny bone cells.
Human Body There are 12 major anatomy systems: Skeletal, Muscular, Cardiovascular, Digestive, Endocrine, Nervous, Respiratory, Immune/Lymphatic, Urinary, Female Reproductive, Male Reproductive, Integumentary. Skeletal System The skeletal system includes all of the bones and joints in the body.

Compact bone is dense so that it can withstand compressive forces, while spongy bone (also called cancellous bone) has open spaces and is supportive, but also lightweight and can be readily remodeled to accommodate changing body needs. Compact Bone. Compact bone is the denser, stronger of the two types of osseous tissue (Figure 6.3.6). It makes
Bone Facts. The smallest bone in the human body is called the stirrup bone, located deep inside the ear. It's only about 3 millimeters long in an adult. The longest bone in the human is called the femur, or thigh bone. It's the bone in your leg that goes from your hip to your knee. In an average adult, it's about 20 inches long. Bone is living tissue that makes up the body's skeleton. There are 3 types of bone tissue: Compact tissue. This is the harder, outer tissue of bones. There are 206 bones in the adult human skeleton. This doesn't include teeth or small bones found within tendons called sesamoid bones. The 206 bones include: Skeletal system The skeletal system is composed of bones and cartilages.There are two parts of the skeleton; axial and appendicular. The axial skeleton consists of the bones of the head and trunk.The appendicular skeleton consists of the bones within the limbs, as well as supporting pectoral and pelvic girdles.. There are 206 bones in an adult human body.

human skeleton, the internal skeleton that serves as a framework for the body. This framework consists of many individual bones and cartilages.There also are bands of fibrous connective tissue—the ligaments and the tendons—in intimate relationship with the parts of the skeleton. This article is concerned primarily with the gross structure and the function of the skeleton of the normal The largest bone in the human body is the thighbone, or femur, and the smallest is the stapes in the middle ear, at around 3 millimeters long. Bones consist mostly of the protein collagen , which
