| central nervous system stimulants | A loosely defined group of drugs that tend to increase behavioural alertness, agitation, or excitation. They work by a variety of mechanisms, but usually not by direct excitation of neurons. The many drugs that have such actions as side effects to their main therapeutic use are not included here.

| central ossifying fibroma | <tumour> A painless, slow-growing, expansile, sharply circumscribed benign fibro-osseus tumour of the jaws that is derived from cells of the periodontal ligament; presents initially as a radiolucency that becomes progressively more opaque as it matures. See: central cementifying fibroma. (05 Mar 2000) |
| central osteitis | <pathology> Inflammation of bone caused by a pyogenic organism. It may remain localised or may spread through the bone to involve the marrow, cortex, cancellous tissue and periosteum. Origin: Gr. Myelos = marrow (18 Nov 1997) |
| central palmar space | The more medial of the central palmar spaces, bounded medially by the hypothenar compartment; related distally to the synovial tendon sheaths of digits 3 and 4 and proximally to the common flexor sheath. Synonym: medial midpalmar space, middle palmar space. (05 Mar 2000) |
| central paralysis | Paralysis due to a lesion in the brain or spinal cord. (05 Mar 2000) |
| central pit | A depression in the centre of the macula retinae containing only cones and lacking blood vessels. Synonym: fovea centralis retinae, central pit. (05 Mar 2000) |
| central placenta previa | Placenta previa in which the placenta entirely covers the internal os of the cervix. Synonym: central placenta previa, total placenta previa. (05 Mar 2000) |
| central pneumonia | A form of pneumonia in which exudation is confined for a time to the central portion of a lobe or the hilar region. Synonym: core pneumonia. (05 Mar 2000) |
| central pontine myelinolysis | <neurology> A condition characterised by damage to the myelin (sheath) layer of nerve cells in the pons (brainstem). The destruction of myelin inhibits the conduction of a nerve impulse along a nerve cell. The most common cause for exacerbating this condition is a rapid correction of hyponatraemia (low blood sodium level). Some conditions such as Wernicke-Korsakoff syndrome and alcoholism can predispose to loss of myelin. Symptoms can include weakness, double vision, muscle spasms, speech difficulty, delirium, sleepiness, hallucinations, tremors and uncontrolled eye movements. An MRI scan of the brain can demonstrate the abnormality. A more slow controlled correction of serum sodium levels is necessary in these patients. There is no definitive treatment for the underlying disorder. (12 Jan 1998) |

| central retinal artery occlusion | <ophthalmology> The sudden blockage of the retinal artery with a blood clot that commonly leads to a painless but irreversible blindness in that eye. (12 Jan 1998) |
| central retinal fovea | A depression in the centre of the macula retinae containing only cones and lacking blood vessels. Synonym: fovea centralis retinae, central pit. (05 Mar 2000) |
| central retinal vein occlusion | <ophthalmology> The sudden blockage of the retinal vein with blood clot that commonly leads to a painless irreversible blindness in that eye. (12 Jan 1998) |

| central pontine myelinolysis |
Central pontine myelinolysis is a neurologic disease caused by severe damage of the myelin sheath of nerve cells in the brainstem, more precisely in the area termed the pons. The most common cause is the rapid correction of low blood sodium levels (hyponatremia). Some scholars postulate that the real cause might be the lack of a substance that is essential for brain activity and is lacking due to malnutrition. ...

| central nervous system |
The central nervous system is composed of the brain, spinal cord, and the meninges (protective membranes surrounding them). Although HIV infects monocytes and macrophages, they appear to be relatively resistant to killing. These cells travel throughout the body and carry HIV to various organs, especially the lungs and the brain. Persons living with HIV often experience abnormalities in the central nervous system. ...
