pal·mar re·flex

(pahl'măr rē'fleks) One of the primitive reflexes: flexion of the fingers occurs when the palm of the hand is irritated. The reflex emerges at 11 weeks in utero, is fully present at birth, and usually inhibited by 2-3 months of life; replaced by the pincer grip at 36 weeks of age. When retained beyond 4-5 months of life, it impedes both manual dexterity and manipulatory activities. One of a group of reflexes that affect handwriting, speech, and articulation.
Synonym(s): infant grasp reflex.
