Answer: Mesenteric and omental soft tissue nodules could have a number of causes, usually metastatic cancer. In a patient with a known soft tissue sarcoma elsewhere in the body, this finding would likely represent metastases from this sarcoma. If the patient did not have a history of soft tissue sarcoma, this finding could be several things, and soft tissue sarcome would not be at the top of my list.
Answer: Sarcomas are malignancies that arise from mesenchymal tissues: (think of middle layers of body) bone, cartilage, muscle, fat, blood vessels. Examples are osteosarcoma-bone, chondrosarcoma-cartlilage, liposarcoma-fat, myosarcoma-muscle, and angiosarcoma-blood vessel.
Answer: The internal surfaces such as inside blood vessels and lymph nodes are covered by endothelium and the external surfaces are covered by epithelium. "Epithelial tissues line the cavities and surfaces of structures throughout the body, and also form many glands." (Wikipedia)
Answer: The entire body, aside from the bones, is considered "Soft Tissue." The answer to this question will be location-specific. To know what soft tissues are "underlying" an area, we need to know what area we are talking about. The term underlying just means, "deeper inside the body." So, underlying the skin is the surface fascia (aka connective tissue), the capillary beds, and so forth. Underlying the abdominal muscle wall is the abdominal cavity, filled with the organs of digestion and elimination, etc. So "underlying soft tissue" means whatever organs or structures are present deeper inside the body at that location. The underlying soft tissues of your arm include the biceps and triceps muscles, and the blood vessels and nerves supplying energy to them, etc. The underlying soft tissues of your head include the tongue, the eyes, the brain, the glands, the jaw muscles, etc.
Answer: Cartilage is a soft tissue that insulates and protects bones fromone another. The wearing of knee cartilage or chondromalacia iscaused by the degeneration and loss of soft cartilage tissue.Healthy cartilage protects the knee joint from such wear, andfuture osteo-arthritic conditions.
Answer: Scar tissue that forms in the liver is called cirrhosis.Technically cirrhosis is not a "disease"; it is a stage ofliver malfunction. In fact, it is the final stage after fibrosis.Cirrhosis of the liver is most often caused by alcoholism, but canbe caused by other diseases as well.
Answer: These are called adipose tissues and there are two types, the brownadipose and white adipose. Both are abundant in newborns and alsoin animals that hibernate. Their primary function is to generateheat in the body.
