Collarbone
Collarbone A horizontal bone above the first rib that makes up the front part of the shoulder.
RELATED TERMS--------------------------------------
Bone Bone refers either to a hardened connective tissue or to one of the individual structures, or organs, into which it is formed, found in many animals. Bones support body structures, protect internal organs, and (in conjunction with muscles) facilitate movement; are also involved with cell formation, calcium metabolism, and mineral storage. The bones of an animal are, collectively, known as the skeleton.
Shoulder The ball-and-socket joint connecting the arm with the body.
SIMILAR TERMS--------------------------------------
Collagen At a microscopic level, this is the 'skeleton' of most tissues in the body.
Collagen disease See 'Connective tissue disease'.
Collagen injection The practice of injecting collagen into a part of the face or body to make it larger, most often performed on the lips. The effects are long lasting but not permanent. Collagen injections are normally done by a plastic surgeon.
Collagenous colitis A type of colitis. Caused by an abnormal band of collagen, a thread-like protein.
Collapsed lung Failure of full expansion of a once fully expanded lung. Medically called atelectasis.
Collateral In anatomy, a collateral is a subordinate or accessory part. A collateral is also a side branch, as of a blood vessel or nerve.
Collateral Blood Vessels Small capillary-like branches of the artery that form over time in response to narrowed coronary arteries. The collaterals "bypass" the area of narrowing and help to restore blood flow. However, during times of increased exertion, the collaterals may not be able to supply enough oxygen-rich blood to the heart muscle.
Collateral knee ligament, lateral The knee joint is surrounded by a joint capsule with ligaments strapping the inside and outside of the joint (collateral ligaments) as well as crossing within the joint (cruciate ligaments). These ligaments provide stability and strength to the knee joint. The lateral collateral ligament of the knee is on the outside of the joint.
Collateral knee ligament, medial The knee joint is surrounded by a joint capsule with ligaments strapping the inside and outside of the joint (collateral ligaments) as well as crossing within the joint (cruciate ligaments). These ligaments provide stability and strength to the knee joint. The medial collateral ligament of the knee is on the inner side of the joint.
Collective unconscious (universal consciousness) Alleged inborn psychological bedrock--common to all humans but varying with the particular society, people, or race--that enables telepathy.

PREVIOUS AND NEXT TERMS--------------------------------------
Colitis, pseudomembranous Severe inflammation of the inner lining of the colon due usually to the clostridium difficile (C.difficile) bacterium, one of the most common causes of infection of the large bowel (colon) in the United States, affecting millions of patients yearly. Patients taking antibiotics are at risk of becoming infected with C. difficile. Antibiotics disrupt the natural bacteria of the bowel, allowing C. difficile bacteria to become established in the colon. Many persons infected with C. difficile bacteria have no symptoms. These people become carriers of the bacteria and can infect others. In some people, a toxin produced by C. difficile causes diarrhea, abdominal pain, severe inflammation of the colon (colitis), fever, an elevated white blood count, vomiting and dehydration. Rarely, the walls of the colon wear away and holes develop (colon perforation), which can lead to a life-threatening infection of the abdomen.
Colitis, spastic A common gastrointestinal disorder involving an abnormal condition of gut contractions (motility) characterized by abdominal pain, bloating, mucous in stools, and irregular bowel habits with alternating diarrhea and constipation, symptoms that tend to be chronic and to wax and wane over the years. Although the disorder can cause chronic recurrent discomfort, it does not lead to any serious organ problems.
Colitis, ulcerative A relatively common disease that causes inflammation of the large intestine (the colon). The cause is unknown.
Collagen injection The practice of injecting collagen into a part of the face or body to make it larger, most often performed on the lips. The effects are long lasting but not permanent. Collagen injections are normally done by a plastic surgeon.
Collapsed lung Failure of full expansion of a once fully expanded lung. Medically called atelectasis.

Colon cancer and polyps Benign tumors of the large intestine are called polyps. Malignant tumors of the large intestine are called cancers. Benign polyps do not invade nearby tissue or spread to other parts of the body. Benign polyps can be easily removed during colonoscopy, and are not life threatening. If benign polyps are not removed from the large intestine, they can become malignant (cancerous) over time. Most of the cancers of the large intestine are believed to have developed from polyps.
Colon cancer family history A family history of colorectal cancer (CRC). First-degree relatives of people with CRC are themselves at a 2 to 3-fold increased risk of colorectal cancer. (Parents, brothers and sisters, and children are first-degree relatives.) When the family history includes 2 or more relatives with CRC, the possibility of an inherited CRC syndrome is increased.
