| cuticle | <plant biology> A continuous layer of waxy substances covering over the outer surfaces of the epidermis of plants, it contains cutin and protects against water loss / water gain and other damage. (13 Nov 1997) |
| cuticle of hair | A layer of overlapping shingle-like cells that invest the hair cortex and serve to lock the hair shaft in its follicle. Synonym: cuticle of hair. Cuticula vaginae folliculi pili, cuticle of overlapping shingle-like cells lining the follicle of the hair. Synonym: cuticle of root sheath. (05 Mar 2000) |
| cuticle of nail | The exposed distal prolongation of the corneal layer of the deep surface of the proximal nail fold (eponychium), seen as a thin "skin" overlapping and adherent to the body of the nail at its proximal portion (the area of the lunula). It is formed as a remnant of the eponychium which otherwise degenerates by the eighth month of pregnancy. (05 Mar 2000) |

| Nasmyth's cuticle | The primary enamel cuticle, consisting of two extremely thin layers (the inner one clear and structureless, the outer one cellular), covering the entire crown of newly erupted teeth and subsequently abraded by mastication; it is evident microscopically as an amorphous material between the attachment epithelium and the tooth. Synonym: cuticula dentis, adamantine membrane, dental cuticle, membrana adamantina, Nasmyth's cuticle, Nasmyth's membrane, skin of teeth. (05 Mar 2000) |

| acquired | In medicine, the word acquired means new or added. New in the sense that it is not genetic (inherited) and added in the sense that is was not congenital (present at birth) but came along later. For example, AIDS is an acquired, not a genetic form of immune deficiency. (12 Dec 1998) |
| acquired agammaglobulinaemia | Heterogeneous group of immunodeficiency syndromes characterised by hypogammaglobulinaemia of most isotypes, variable B-cell defects, and the presence of recurrent bacterial infections. (12 Dec 1998) |
| acquired bronchiectasis | <chest medicine> Persistent and progressive dilation of bronchi or bronchioles as a consequence of inflammatory disease (lung infections), obstruction (tumour) or congenital abnormality (for example cystic fibrosis). Symptoms include fetid breath and paroxysmal coughing, with the expectoration of mucopurulent matter. It may affect the bronchioles uniformly (cylindric bronchiectasis) or occur in irregular pockets (sacculated bronchiectasis) or the dilated bronchi may have terminal bulbous enlargements (fusiform bronchiectasis). Although rarely congenital, it is most often an acquired condition in childhood. (13 Nov 1997) |

| acquired character | A character developed in a plant or animal as a result of environmental influences during the individual's life. (05 Mar 2000) |
| acquired drives | Those drives not directly related to biological needs; a secondary drive can be learned as an offshoot of a primary drive, in which case it is often referred to as a motive. Synonym: acquired drives. (05 Mar 2000) |
| acquired eccentric relation | An eccentric relation that is assumed by habit in order to bring the teeth into occlusion. (05 Mar 2000) |
