lanugo(lă-nū′gō) [L. lana, wool]
1. Downy hair covering the body.
2. Fine downy hairs that cover the body of the fetus, esp. when premature. The presence and amount of lanugo aids in estimating the gestational age of preterm infants. The fetus first exhibits lanugo between weeks 13 and 16. By gestational week 20, it covers the face and body. The amount of lanugo is greatest between weeks 28 and 30. As the third trimester progresses, lanugo disappears from the face, trunk, and extremities.lanuginous, adjective
