| foetal haemoglobin | <chemical> The form of haemoglobin normally comprising more than half of the haemoglobin in the foetus, composed of two alpha and two gamma polypeptides. It is also present in minimal amounts in adulthood and is abnormally elevated in aplastic anaemia, leukaemia, and certain types of thalassaemia. It has higher affinity for oxygen under physiologic conditions than does haemoglobin a. Chemical name: Haemoglobin F (12 Dec 1998) |

| foetal heart | The heart of the foetus of any viviparous animal. It refers to the heart in the postembryonic period and is differentiated from the embryonic heart (heart/embryology) only on the basis of time. (12 Dec 1998) |
| foetal heart rate | In the foetus, the number of heart beats per minute, normally 120 to 160. (05 Mar 2000) |
| foetal hydrops | <radiology> Immune, Rh sensitization (erythroblastosis foetalis), non-immune, thalassaemia, structural defects (e.g., lung tumour), cardiac arrhythmia (secondary to conduction defect), ultrasound findings: foetal ascites and/or pleural or pericardial effusion, subcutaneous oedema, polyhydramnios, thick, hydropic placenta (12 Dec 1998) |
| foetal inclusion | Unequal conjoined twins in which the incompletely developed parasite is wholly enclosed in the autosite. (05 Mar 2000) |
| foetal macrosomia | A complication of gestational diabetes mellitus or prolonged pregnancy. A macrosomic foetus is defined as weighing more than 4000 grams. (12 Dec 1998) |
| foetal medicine | Study of the growth, development, care, and treatment of the foetus, and of environmental factors harmful to the foetus. Synonym: fetology. (05 Mar 2000) |
| foetal membrane | A structure or tissue that develops from the fertilised ovum but does not form part of the embryo proper. Synonym: embryonic membrane, extraembryonic membrane. (05 Mar 2000) |
| foetal membranes | Thin layers of tissue which surround the embryo or foetus and provide for its nutrition, respiration, excretion and protection; they are the yolk sac, allantois, amnion, and chorion. (12 Dec 1998) |
| foetal membranes, premature rupture | Spontaneous rupture of amniotic sac before the onset of uterine contractions. (12 Dec 1998) |
| foetal monitoring | Physiologic or biochemical monitoring of the foetus. It is usually done during labour and may be performed in conjunction with the monitoring of uterine activity. It may also be performed prenatally as when the mother is undergoing surgery. (12 Dec 1998) |
| foetal mortality rate | <epidemiology> The ratio of foetal deaths divided by the sum of the births (the live births + the foetal deaths) in that year. In the United States, the foetal mortality rate plummeted from 19.2 per 1,000 births in 1950 to 9.2 per 1,000 births in 1980. (12 Dec 1998) |
| foetal movement | <obstetrics> Movement of the foetus in the womb perceived by the mother and felt by palpation of the abdomen. The first foetal movements felt by the mother during pregnancy (quickening) are usually between18 and 22 weeks of pregnancy. (08 Mar 2000) |
| foetal organ maturity | <embryology> Functional competence of specific foetal organs or body systems. In humans, it is usually assessed by analysis of amniotic fluid, as in the assessment of foetal lung maturity by analysis for components of pulmonary surfactant. (08 Mar 2000) |
| foetal ovoid | <embryology> The form of the foetus in utero; its length is about one-half of the length of the extended foetus. (05 Mar 2000) |
