| skeletal muscle tissue | <anatomy, pathology> A rather non-specific term usually applied to the striated muscle of vertebrates that is under voluntary control. The muscle fibres are syncytial and contain myofibrils, tandem arrays of sarcomeres. (18 Nov 1997) |
|---|---|
| skin and connective tissue diseases | A collective term for diseases of the skin and its appendages and of connective tissue. (12 Dec 1998) |
| smooth muscle tissue | <anatomy, pathology, physiology> Muscle tissue in vertebrates made up from long tapering cells that may be anything from 20-500m long. Smooth muscle is generally involuntary and differs from striated muscle in the much higher actin/myosin ratio, the absence of conspicuous sarcomeres and the ability to contract to a much smaller fraction of its resting length. Smooth muscle cells are found particularly in blood vessel walls, surrounding the intestine (particularly the gizzard in birds) and in the uterus. The contractile system and its control resemble those of motile tissue cells (e.g. Fibroblasts, leucocytes) and antibodies against smooth muscle myosin will cross react with myosin from tissue cells, whereas antibodies against skeletal muscle myosin will not. See: dense bodies. (18 Nov 1997) |
| soft tissue infections | Infections of non-skeletal tissue, i.e., exclusive of bone, ligaments, cartilage, and fibrous tissue. The concept is usually referred to as skin and soft tissue infections and usually subcutaneous and muscle tissue are involved. The predisposing factors in anaerobic infections are trauma, ischemia, and surgery. The organisms often derive from the faecal or oral flora, particularly in wounds associated with intestinal surgery, decubitus ulcer, and human bites. (12 Dec 1998) |
| soft tissue injuries | Injuries of tissue other than bone. The concept is usually general and does not customarily refer to internal organs or viscera. It is meaningful with reference to regions or organs where soft tissue (muscle, fat, skin) should be differentiated from bones or bone tissue, as "soft tissue injuries of the hand". (12 Dec 1998) |
| soft tissue neoplasms | Neoplasms of whatever cell type or origin, occurring in the extraskeletal connective tissue framework of the body including the organs of locomotion and their various component structures, such as nerves, blood vessels, lymphatics, etc. (12 Dec 1998) |
| soft tissue sarcoma | A sarcoma that begins in the muscle, fat, fibrous tissue, blood vessels, or other supporting tissue of the body. Not a type of bone cancer. (12 Dec 1998) |
| soft tissue window | mediastinal window |
| nasion soft tissue | The outer point of intersection between the nasion-sella line and the soft tissue profile. (05 Mar 2000) |
| neoplasms, adipose tissue | Neoplasms composed of fatty tissue or connective tissue made up of fat cells in a meshwork of areolar tissue. The concept does not refer to neoplasms located in adipose tissue. (12 Dec 1998) |
| neoplasms, bone tissue | Neoplasms composed of bony tissue, whether normal or of a soft tissue which has become ossified. The concept does not refer to neoplasms located in bones. (12 Dec 1998) |
| neoplasms, connective and soft tissue | Neoplasms developing from some structure of the connective and subcutaneous tissue. The concept does not refer to neoplasms located in connective or soft tissue. (12 Dec 1998) |
| neoplasms, connective tissue | Neoplasms composed of connective tissue, including elastic, mucous, reticular, osseous, and cartilaginous tissue. The concept does not refer to neoplasms located in connective tissue. (12 Dec 1998) |
| neoplasms, fibrous tissue | Neoplasms composed of fibrous tissue, the ordinary connective tissue of the body, made up largely of yellow or white fibres. The concept does not refer to neoplasms located in fibrous tissue. (12 Dec 1998) |
| neoplasms, gonadal tissue | Neoplasms composed of ovarian or testicular tissue. This concept does not refer to neoplasms located in the ovaries or testes. (12 Dec 1998) |
