| rotator cuff | <anatomy> The rotator cuff is a tendon formed by three distinct muscles: teres minor, supraspinatus and infraspinatus, which stabilise the head of the humerus within the shoulder joint. Tendinitis or injury to the rotator cuff muscle can make shoulder abduction (lifting the arm out to the side) and external rotation painful. In most cases treatment includes rest, ice and physical therapy to strengthen the shoulder muscles. (13 Nov 1997) |

| cuff | Any structure shaped like a cuff. (05 Mar 2000) |
| medial rotator | A muscle that turns a part medialward. See: invertor. Synonym: medial rotator. (05 Mar 2000) |
| cervical rotator muscles | The rotator muscles attached to the cervical vertebrae. Synonym: musculi rotatores cervicis, cervical rotator muscles. (05 Mar 2000) |
| rotator | 1. <anatomy> That which gives a rotary or rolling motion, as a muscle which partially rotates or turns some part on its axis. 2. <chemistry> A revolving reverberatory furnace. Origin: L. Source: Websters Dictionary (01 Mar 1998) |
| rotator muscles | Deepest of the three layers of transversospinalis muscles, chiefly developed in the thoracic region; they arise from the transverse process of one vertebra and are inserted into the root of the spinous process of the next two or three vertebrae above; action, traditionally described as a column, it is more likely that these muscles, provided with a very high density of muscle spindles, are organs of proprioception; nerve supply, dorsal primary rami of the spinal nerves. Synonym: musculi rotatores, rotator muscles. (05 Mar 2000) |
| thoracic rotator muscles | The rotators of the thoracic vertebrae. Synonym: musculi rotatores thoracis, thoracic rotator muscles. (05 Mar 2000) |
| faraday rotator | <radiobiology> A device which rotates the plane of polarization of an optical-light pulse, typically by using a glass disc suitably doped with a magnetic ion and placed in a magnetic field. These devices are used to isolate (protect) a laser amplifier chain against back-reflection from the laser target, the Faraday rotator in this case gives a 90-degree phase change on the round trip, so that the returning light is rejected by a polarizer which transmits the outgoing light. Magnetised plasmas also display the Faraday rotation effect of light waves propagating along the magnetic field lines. (09 Oct 1997) |
| lumbar rotator muscles | The rotator muscles of the lumbar vertebrae. Synonym: musculi rotatores lumborum, lumbar rotator muscles. (05 Mar 2000) |
| aaa disease | Endemic anaemia of ancient Egypt, ascribed in the Papyrus Ebers to intestinal infestation with ancylostoma; now called ancylostomiasis. (05 Mar 2000) |
| ABO haemolytic disease of the newborn | Erythroblastosis foetalis due to maternal-foetal incompatibility with respect to an antigen of the ABO blood group; the foetus possesses A or B antigen which is lacking in the mother, and the mother produces immune antibody which causes haemolysis of foetal erythrocytes.

| accumulation disease | A disease characterised by abnormal accumulation of a metabolic product in certain cells and tissues; examples include the mucopolysaccharidoses, lipoidoses. (05 Mar 2000) |
| Acosta's disease | A condition that results from prolonged exposure to high altitude. Symptoms include a continuous dry cough, shortness of breath, poor exercise tolerance, dizziness, headache, sleep difficulty, anorexia, confusion, fatigue and a rapid pulse. Treatment includes the immediate movement to a lower altitude. Prophylaxis has been accomplished successfully with the use of acetazolamide (Diamox). (27 Sep 1997) |
