| oedipal phase | In psychoanalysis, a stage in the psychosexual development of the child, characterised by erotic attachment to the parent of the opposite sex, repressed because of fear of the parent of the same sex; usually occurring between the ages of 3 and 6 years. Synonym: oedipal period. (05 Mar 2000) |
| oral phase | In psychoanalytic personality theory, the earliest stage in psychosexual development, lasting through the first 18 months of life, during which the oral zone is the centre of the infant's needs, expression, gratification, and pleasurable erotic experiences; has a strong influence on the organization and development of the child's psyche.

| early-phase response | Prompt onset of symptoms following an antigenic stimulus. (05 Mar 2000) |
| eclipse phase | The time between infection by (or induction of) a bacteriophage, or other virus, and the appearance of mature virus within the cell; an interval of time during which viral infectivity cannot be recovered. Synonym: eclipse phase. (05 Mar 2000) |
| eruptive phase | That period in the tooth formation which includes the development of the roots, periodontal ligament, and dentogingival junction of the tooth. (05 Mar 2000) |

| lag phase | <cell culture> The initial growth phase of a culture, during which cell number remains relatively constant prior to rapid growth. (09 Oct 1997) |
| lamellar phase | <biochemistry> A lamellar organisation of phospholipids that are packed as a bilayer with hydrophobic acyl tails inwardly directed and polar head groups on the outside surfaces. It is this bilayer that forms the basis of membranes in cells, though in most cellular membranes a very substantial proportion of the area may be occupied by integral proteins. The triple layered appearance of membranes seen in electron microscopy is thought to arise because the osmium tetroxide binds to the polar regions leaving a central, unstained, hydrophobic region. (31 Dec 1997) |
| follicular phase | <gynaecology, physiology> The follicular phase is the pre-ovulatory phase of a woman's reproductive cycle during which the follicle grows and high oestrogen levels cause the uterine lining to grow. (09 Oct 1997) |
