| muscle relaxants, central | A heterogeneous group of drugs used to produce muscle relaxation, excepting the neuromuscular blocking agents. They have their primary clinical and therapeutic uses in the treatment of muscle spasm and immobility associated with strains, sprains, and injuries of the back and, to a lesser degree, injuries to the neck. They have been used also for the treatment of a variety of clinical conditions that have in common only the presence of skeletal muscle hyperactivity, for example, the muscle spasms that can occur in multiple sclerosis.

| myelinolysis, central pontine | A form of massive demyelination of the pons occurring in malnutrition and alcoholism. The remarkable unsystematic dissolution of the sheaths of medullated fibres is its most certain feature. The lesion varies from only a few millimeters in diameter to almost the entire pons. The basic pathology is the destruction of the medullated sheaths throughout the lesions with relative sparing of the axis cylinders and intactness of the nerve cells of the pontine nuclei. Pathologically it is easily differentiated from infarction and the inflammatory demyelinations of multiple sclerosis and postinfectious encephalomyelitis. There does not appear to be a genetic, sex, or age factor. It is often, however, associated with some other serious disease, particularly chronic alcoholism.

| posterior central convolution | The anterior convolution of the parietal lobe, bounded in front by the central sulcus (fissure of Rolando) and posteriorly by the interparietal sulcus. Synonym: gyrus postcentralis, ascending parietal convolution, ascending parietal gyrus, posterior central convolution, posterior central gyrus. (05 Mar 2000) |

Synonym: gyrus postcentralis, ascending parietal convolution, ascending parietal gyrus, posterior central convolution, posterior central gyrus. (05 Mar 2000) |
| hearing loss, central | Hearing loss due to central nervous system disease, anywhere in the auditory pathways from the cochlear nucleus of the pons to the auditory cortex. (12 Dec 1998) |
| short central artery | <anatomy, artery> A branch of the precommunical part of the anterior cerebral artery. Synonym: arteria centralis brevis. (05 Mar 2000) |
| simple-central anisocoria | A common (20% of normals) benign inequality of the pupils that may change from one hour to the next. Synonym: essential anisocoria, physiologic anisocoria, simple-central anisocoria. (05 Mar 2000) |
| neuro-central | <anatomy> Between the neural arch and the centrum of a vertebra; as, the neurocentral suture. Source: Websters Dictionary (01 Mar 1998) |
| superior central tegmental nucleus | Collections of small neurons centrally scattered among many fibres from the level of the trochlear nucleus in the midbrain to the hypoglossal area in the medulla oblongata. (12 Dec 1998) |
| disease, central core, of muscle | <anatomy> One of the conditions that produces 'floppy baby' syndrome. CCD causes hypotonia (floppiness) in the newborn baby, slowly progressive muscle weakness, and muscle cramps after exercise. Muscle biopsy shows a key diagnostic finding (absent mitochondria in the centre of many type I muscle fibres). CCD is inherited as a dominant trait. The CCD gene is on chromosome 19 (and involves ryanodine receptor-1). (12 Dec 1998) |
| indians, central american | An ethnic group belonging to the mongoloid racial stock in central america. This does not include mexican indians. (12 Dec 1998) |
| lateral central palmar space | The more lateral (radial) of the central palmar spaces, bounded laterally by the thenar compartment; related distally to the synovial tendon sheath of the index finger and proximally to the common flexor sheath. Synonym: lateral midpalmar space. (05 Mar 2000) |
| free-central | A placentation in which the ovules are borne on a free-standing central placenta within the ovary. (09 Oct 1997) |
| long central artery | <anatomy, artery> Long posterior ciliary artery, one of two branches of the ophthalmic running forward between the sclerotic and choroid coats to the iris, at the outer and inner margins of which they form by anastomosis two circles. Synonym: arteria ciliaris posterior longa, medial striate artery. (05 Mar 2000) |
