| rate, maternal mortality | The number of maternal deaths related to childbearing divided by the number of live births (or by the number of live births + foetal deaths) in that year. The maternal mortality rate in the united states in 1993 (and 1994) was 0.1 per 1,000 live births, or 1 mother dying per 10,000 live births. (12 Dec 1998) |

| maternal cotyledon | A unit of the placenta made up of trophoblastic cells, fibrous tissue, and abundant blood vessels, which is visible grossly on the maternal surface as an irregularly shaped lobe circumscribed by a deep cleft and made up of a stem villus with numerous branching free villi and anchoring villi; placental vessels in the chorionic plate supply the stem villus and its branches, allowing gas and metabolite exchange across the trophoblastic layer with maternal blood in the intervillous space; traditionally called clinicians' cotyledon.

| maternal death | Death of a woman while pregnant or within 42 days after the termination of gestation, irrespective of the duration and site of pregnancy and the cause of death; two periods are recognised in the 42-day interval: period 1 includes day 1 to day 7; period 2 includes day 8 to day 42.

| maternal effect gene | Gene, usually required for early embryonic development, whose product is secreted into the egg by the mother. The phenotype is thus determined by the mother's, rather than the egg's, genotype. Compare:. Zygotic effect gene. See: egg polarity gene. (18 Nov 1997) |
| maternal exposure | Exposure of the female parent, human or animal, to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals that may affect offspring.
