专业术语—口腔生理学术语C2(英文详解)
Cemento-enamel 1 junction 2- the junction between the enamel covering the crown of the tooth and the cementum covering its root. Often referred to as the CEJ.
Cementoblasts - cells of mesenchyme origin, induced by proteins from cells of ectodermal origin, to form a layer of cementum around the roots of teeth.
Cementum - a thin layer of bone-like material covering the roots of teeth and sometimes the enamel surface, containing both extrinsic 3 and intrinsic fibres.
Central nervous system - the brain and spinal 4 cord. The nerves which leave the spinal cord and brain comprise the peripheral 5 nervous system.
Chemotaxis - the movement of cells in response to chemical messengers. The movement of neutrophils and macrophages into damaged tissues is brought about by signals released by damaged tissues, and bacterial 6 products.. The term applies to the movement of any organism attracted by a specific chemical, which may be a suitable nutrient 7.
Cholinergice - cell receptors specific for the neurotransmitter acetyl choline. Cholinergic receptors are found at neuromuscular junctions 8 of muscle fibres and at all the synaptic junctions of the parasympathetic nervous system. They are also found at the pre- ganglionic synapse 9 of the sympathetic nervous system.
Chondroitin sulphate - the major glycosaminoglycan of cartilage , the other being keratan sulphate.
Chromosomes 11 - structures in the nucleus 12 of a cell which appear visible during cell division. Each chromosome 10 (humans have 24) is a tightly coiled string of DNA 13 wound round a protein.
Clearance 14 - the removal by swallowing, of substance in the mouth. Clearance is dependent on the completeness of swallowing and the rate of flow of saliva 15.
Clones - a family of cells, or organisms, which are all identical to a single parent. They are produced by asexual reproduction. When a B lymphocytes has recognised a foreign antigen, it provides millions of identical daughter cells in order to produce the specific antibodies in large quantities.
