The odontoid process is also removed with the high speed drill and diamond burr. The latter prevents soft tissue (ligamentous) damage and is used in the deeper parts of the bony structures. 

Joints are stmcturaHy unique. They permit bodily movement and are bound together by fibrous tissues known as ligaments. Most larger joints are encapsulated in a bursa sac and surrounded by synovial fluid which lubricates the joint continuously to reduce friction. The skeleton is constmcted of various types of moveable joints. Some joints allow for no movement, such as those connecting the bones of the skull. Other joints permit only limited movement. For example, the joints of the spine allow limited movement in several directions. Most joints have a greater range of motion than the joints of the skull and spine. 

Tendons are composed of fibrous connective tissue. Tendon tissue is also formed by the fibroblast ceUs, similar to the way ligaments are formed. These fibroblast ceUs then further differentiate into other specialized ceUs known as fibrocytes. Mature fibrocytes are inactive and compose the ceUular portion of tendons. The function of the tendon is to attach muscles to bones and other parts. 

Soft Tissue Injuries. Some of the more common soft tissue injuries are sprains, strains, contusions, tendonitis, bursitis, and stress injuries, caused by damaged tendons, muscles, and ligaments. A sprain is a soft tissue injury to the ligaments. Certain sprains are often associated with small fractures. This type of injury is normally associated with a localized trauma event. The severity of the sprain depends on how much of the ligament is torn and to what extent the ligament is detached from the bone. The areas of the human body that are most vulnerable to sprains are ankles, knees, and wrists. 

A contusion is an injury to soft tissue in which the skin is not penetrated, but swelling of broken blood vessels causes a bmise. The bmise is caused by a blow of excessive force to muscle, tendon, or ligament tissue. A bmise, also known as a hematoma, is caused when blood coagulates around the injury causing swelling and discoloring skin. Most contusions are mild and respond well to rest, ice, compression, and elevation of the injured area. 

The musculoskeletal system consists of bones, blood vessels, nerves, ligaments, tendons, muscles, and cartilage, which work together to perform the structural and kinematic functions of the organism. These musculoskeletal tissues all have a composite structure of cells embedded in a matrix produced by the cells themselves. 

Figure 7.3. All skeletal tissues arise from a single cell type, the mesenchymal stem cell. Differentiation into bone, cartilage, muscle, or ligament occurs in response to the mechanical and biochemical stimuli of the stem cell s environment.

As noted above, the presence of Met(O) in proteins would go undetected after acid hydrolysis and subsequent amino acid analysis. Thus, since this method of hydrolysis is most commonly used, it is impossible to ascertain from the literature the abundance of Met(O) residues normally present in proteins. However, a number of studies have reported the presence of Met(O) residues in various proteins using one of the appropriate procedures described above. It has been found that Met(O) residues comprise 30% of the total Met in proteins isolated from bovine glomerular basement membranes and anterior lens . Other investigators have reported that the levels of Met(O) in proteins of the trabecular meshwork of human eyes increased with the age of the donor . The amount of Met(O) detected ranged from 15% (10 years old) to 55% (79 years old) of the total methionine content found in the tissue samples. Other studies have shown that in certain species of clams the proteins of the hinge ligament contain only Met(0) residues and no Met . In addition, it has also been reported that as much as 18% of the Met residues in pea seed proteins is in the form of Met(O) . Lastly, Met(O) residues have been found in... 

The musculoskeletal system consists of the muscles, bones, joints, tendons, and ligaments. Disorders related to the musculoskeletal system often are classified by etiology. Acute soft-tissue injuries include strains and sprains of muscles and ligaments. Repeated movements in sports, exercise, work, or activities of daily living may lead to repetitive strain injury, where cumulative damage occurs to the muscles, ligaments, or tendons.1-3 While tendonitis and bursitis can arise from acute injury, more commonly these conditions occur as a result of chronic stress.3,4 Other forms of chronic musculoskeletal pain, such as pain from rheumatoid arthritis (see Chap. 54) or osteoarthritis (see Chap. 55), are discussed elsewhere in this text. 

Skeletal muscle consists of muscle fibers linked together by connective tissue. Tendons and ligaments are composed of collagenous fibers that have a restricted capability to stretch. Tendons connect the muscle to the bone, whereas ligaments connect bone to bone (Fig. 57-1). 

Magnetic resonance imaging (MRI) Soft-tissue imaging to evaluate for tendon or ligament tears. 

Ultrasound Superficial soft-tissue imaging to evaluate for tears in tendons or ligaments. Does not penetrate bone, so it is of limited usefulness for assessing tendons or ligaments deep within joints. 

Ligament of Treitz Suspensory muscle of the duodenum the tissue that connects the duodenum to the diaphragm. 

The physical properties of various types of cartilage include flexibility, non-compressibilty and slipperyness. These characteristics reflect the roles played by the tissue as tendons and ligaments, lining joints, intervertebral discs, and in several sites within the respiratory system. 

Collagen synthesized in the absence of ascorbic acid (i.e. without hydroxyproline) cannot form its usual stable structure. Collagen is a major component of the structural and connective tissues of the body bone, cartilage, tendons, ligaments, teeth, and skin. Small wonder that things sort of fall apart in the absence of adequate ascorbic acid to support the activity of prolyl hydroxylase. 

Dense connective tissue This tissue has a large number of fibres. They may be irregularly arranged, as in the dermis, or in sheaths around tendons and nerves, or more regularly organised in the tendons, which link muscles to bones, and in ligaments which connect bone to bone.
