| compression of tissue | The property of tissue that permits it to be moved from an initial or relaxed position or form. Synonym: compression of tissue. (05 Mar 2000) |
|---|---|
| compression paralysis | Paralysis due to external presure on a nerve. (05 Mar 2000) |
| compression plating | A technique for internal fixation of fractures in which plates and screws are applied so as to produce compression of the line of fracture. (05 Mar 2000) |
| compression retinopathy | See: Berlin's oedema. See: traumatic retinopathy. (05 Mar 2000) |
| compression syndrome | Trauma and ischemia of soft tissues, principally skeletal muscle, due to prolonged severe crushing of the tissues, leading to increased permeability of the cell membrane and to the release of potassium, enzymes, and myoglobin from within cells. Ischemic renal dysfunction secondary to hypotension and diminished renal perfusion results in acute tubular necrosis and uraemia. (12 Dec 1998) |
| compression thrombosis | Thrombosis due to arrest of the circulation in a vessel by compression, as from a tumour. (05 Mar 2000) |
| compression wave | <radiobiology> Waves where the quantity which oscillates is the density of the medium, that is the medium at a given point alternately compresses and expands. Low-amplitude compression waves in air or water are commonly known as sound waves, shock waves are a high-amplitude form. Synonym: density wave. (13 Jan 1998) |
| heat of compression | Heat produced when a gas is compressed. (05 Mar 2000) |
| nerve compression syndromes | Repeated or prolonged pressure on a nerve root or peripheral nerve leading to ischemia, the response to which is oedema above and below the source of pressure. If the pressure is not relieved, fibrosis tends to develop. Types of nerve compression syndromes are the neuropathy caused by intervertebral disk herniation, compression of the median nerve in the carpal tunnel, compression of the ulnar nerve in the elbow, and compression of the lateral cutaneous nerve of the thigh in meralgia paresthetica. This is also called pressure neuropathy. (12 Dec 1998) |
| eyeball compression reflex | Slowing of the heart rate due to the vagal effects of compressing an eyeball. Synonym: eyeball compression reflex. (05 Mar 2000) |
| ulnar nerve compression syndrome | <syndrome> A condition caused by compression or entrapment of the ulnar nerve. It may involve both sensory and motor problems and most often results from compression or entrapment of the ulnar nerve at the elbow (cubital tunnel syndrome). Compression of the nerve may occur during normal activities or as a complication of general anaesthesia. (12 Dec 1998) |
| gangliated cord | One of the two long ganglionated nerve strands alongside the vertebral column that extend from the base of the skull to the coccyx; they are connected to each spinal nerve by gray rami and receive fibres from the spinal cord through white rami connecting with the thoracic and upper lumbar spinal nerves. Synonym: truncus sympathicus, gangliated cord. (05 Mar 2000) |
| genital cord | One of a pair of mesenchymal ridges bulging into the caudal part of the celom of a young embryo and containing the mesonephric and paramesonephric duct. (05 Mar 2000) |
| medial cord of brachial plexus | In the brachial plexus, the bundle of nerve fibres formed by the anterior division of the inferior trunk which lies medial to the axillary artery; it gives off the medial pectoral nerve, the medial brachial cutaneous, and medial antebrachial cutaneous, nerves and end by dividing into the medial root of the median nerves and the ulnar nerve. Synonym: fasciculus medialis plexus brachialis. (05 Mar 2000) |
| vitelline cord | A persistent yolk stalk in the form of a solid cord of tissue connecting ileum to umbilicus. Synonym: omphalomesenteric cord. (05 Mar 2000) |
