Bones

Called osseous tissue, are one of the hardesst materials in the body. Bones are formed from a gradual process before birth called ossification. The first model of the skeleton, made of cartilage, is formed in the fetus. Osteoblasts, immature bone cells, gradually replace the cartilage with bone. In a fully adult bone, the osteoblasts have matured into osteocytes that work to maintain the bone. The formation of strong bones is greatly dependent on an adequate supply of minerals such as calcium and phosphorus.

Bone and Skeleton

Each bone is unique: carries its own blood supply, nerves, and lymphatic vessels. When bones are connected to each other, it forms skeleton. Skeleton protects vital organs and stores minerals. Bone marrow is the site of blood cell production. A joint is the place where two bones meet and are held together by ligaments. This gives flexibility to the skeleton. The skeleton, joints, and muscles work together to produce movement.

Joints

Joints are formed when two or more bones meet. This is also referred to as an articulation. There are three types of joints based on the amount of movement allowed between the bones: synovial joints, cartilaginous joints, and fibrous joints. Most joints are freely moving synovial joints, which are enclosed by an elastic joint capsule. The joint capsule is lined with synovial membrane, which secretes synovial fluid to lubricate the joint. As noted earlier, the ends of bones in a synovial joint are covered by a layer of articular cartilage. Cartilage is very tough, but still flexible. It withstands high levels of stress to act as a shock absorber for the joint and prevents bone from rubbing against bone. Cartilage is found in several other areas of the body, such as the nasal septum, external ear, eustachian tube, larynx, trachea, bronchi, and intervertebral disks. Example of synovial joint is the ball-and-socket joint found at the shoulder and hip. The ball rotating in the socket allows for a wide range of motion. Bands of strong connective tissue called ligaments bind bones together at the joint. Some synovial joints contain a bursa, which is a saclike structure composed of connective tissue and lined with synovial membrane. Most commonly found between bones and ligaments or tendons, bursas function to reduce friction. Some common bursa locations are the elbow, knee, and shoulder joints. Not all joints are freely moving. Fibrous joints allow almost no movement since the ends of the bones are jointed by thick fibrous tissue, which may even fuse into solid bone. The sutures of the skull are an example of a fibrous joint. Cartilaginous joints allow for slight movement but hold bones firmly in place by a solid piece of cartilage. An example of this type of joint is the public symphysis, the point at which the left and right public bones meet in the front of the lower abdomen.

Types of Bones

Long bones, short bones, flat bones, and irregular bones. Long bones are longer than they are wide (femur and humerus). Short bones are roughly as long as they are wide (carpals and tarsals). Irregular bones receives their name because the shape of the bones are very irregular (the vertebrae are irregular bones). Flat bones are usually plate-shaped bones such as the sternum, scapulae, and pelvis. Majority is long bones who have similar structure with a central shaft or diaphysis that widens at each end, which is called an epiphysis. Each epiphysis is covered by a layer of cartilage called articular cartilage to prevent bone from rubbing directly on bone. The remaining surface of each bone is covered with a thin connective tissue membrane called the periosteum, which contains numerous blood vessels, nerves, and lymphatic vessels. The dense and hard exterior surface bone is called cortical or compact bone. Cancellous or spongy bone is found inside the bone. As its name indicates, spongy bone has spaces in it, giving it a spongelike appearance. These spaces contain red bone marrow, which manufactures most of the blood cells and is found in some parts of all bones. The center of the diaphysis contains an open canal called the medullary cavity. Early in life, this cavity also contains red bone marrow, but as we age, the red bone marrow of the medullary cavity gradually converts to yellow bone marrow, which consists primarily of fat cells.

An (dual-energy) absorptiometry is a measurement of bone density using a low-dose X-ray.

Bone Projections and Depressions

Some are rounded and smooth in order to articulate with another bone in a joint. Others are rough to provide muscles with attachment points. The general term for any bony projection is a process. Then there are specific terms to describe the different shapes and locations of carious processes. Some of the common bony process include the following: The head is a large, smooth, ball-shaped end on a long bone. It may be separated from the body or shaft of the bone by a narrow area called the neck. A condyle refers to a smooth, rounded portion at the end of a bone. The epicondyle is a projection located above or on a condyle. The trochanter refers to a large rough process for the attachment of a muscle. A tubercle is a small, rough process the provides the attachment for the tendons and muscles. The tuberosity is a large, rough process that provides the attachment of tendons and muscles. Sinus: a hallow cavity within a bone. Foramen: a smooth, round opening for nerves and blood vessels. Fossa: consists of a shallow cavity or depression on the surface of a bone. Fissue: a slit-type opening.

Skeleton

Two divisions: the axial skeleton and the appendicular skeleton. Axial Skeleton includes the bones of the head, neck, spine, chest, and trunk of the body. These bones form the central axis for the whole body and protect many of the internal organs such as the brain, lungs, and heart. The head or skull is divided into two parts consisting of the cranium and facial bones. These bones surround and protect the brain, eyes, ears, nasal cavity, and oral cavity from injury. The muscles for chewing and moving the head are attached to the cranial bones. The cranium encases the brain and consists of the frontal, parietal, temporal, ethmoid, sphenoid, and occipital bones. The facial bones surround the mouth, nose, and eyes, and include the mandible, maxilla, zygomatic, vomer, palatine, nasal, and lacrimal bones. The hyoid bone is a single U-shaped bone suspended in the neck between the mandible and larynx. It is a point of attachment for swallowing and speech muscles. The trunk of the body consists of the vertebral column, sternum, and rib cage. The vertebral or spinal column is divided into five sections: cervical vertebrae, thoracic vertebrae, lumbar vertebrae, sacrum, and coccyx. Located between each pair of vertebrae, from the cervical through the lumbar regions, is an intervertebral disk. Each disk is composed of fibrocartilage to provide a cushion between the vertebrae. The rib cage has 12 pairs of ribs attached at the back to the vertebral column. Ten of the pairs are also attached to the sternum in the front. The lowest two pairs are called floating ribs and are attached only to the vertebral column. The rib cage serves to provide support for organs, such as the heart and lungs. Appendicular Skeleton Consists of the pectoral girdle, upper extremities, pelvic girdle, and lower extremities. These are the bones for our appendages or limbs and along with the muscles attached to them, they are responsible for body movement. The pectoral girdle consists of the clavicle and scapula bones. It functions to attach the upper extremity, or arm, to the axial skeleton by articulating with the sternum anteriorly and the vertebral column posteriorly. The bones of the upper extremity include the humerus, ulna, radius, carpus, metacarpus, and phalanges. The pelvic girdle is called the os coxae or the innominate bone or hipbone. It contains the ilium, ischium, and pubis. It articulates with the sacrum posteriorly to attach the lower extremity, or leg, to the axial skeleton. The lower extremity bones include the femur, patella, tibia, fibula, tarsus, metatarsus, and phalanges.
