(invertebrate zoology) A depression on the head of termites. fontanelle
fontanelle [fon″tah-nel´] one of the membrane-covered spaces remaining at the junction of the sutures in the incompletely ossified skull of the fetus or infant. Actually there are two soft spots close together, representing gaps in the bone structure which will be filled in by bone during the normal process of growth. The anterior fontanelle is diamond shaped and lies at the junction of the frontal and parietal bones. This fontanelle usually fills in and closes between the eighth and fifteenth months of life. The posterior fontanelle lies at the junction of the occipital and parietal bones, is triangular in shape, and usually closes by the third or fourth month of life. Though these “soft spots” may appear very vulnerable, they may be touched gently without harm. Care should be exercised that they be protected from strong pressure or direct injury. Fontanelles. From Jarvis, 2000.fon·ta·nelle (fon'tă-nel'), [TA] One of several membranous intervals between the angles and margins of the cranial bones in the infant; they include the midline anterior and posterior fontanelles, and the paired sphenoidal and mastoid fontanelles. See: cranial fontanelles. Synonym(s): fonticuli cranii [TA], fonticulus [TA], cranial fontanelles [Fr. dim. of fontaine, fountain, spring] fontanelle A non-ossified area of membranous bone, in particular of the skull in an infant. Fonticulus is the accepted Terminologia Anatomica name; fontanelle is widely preferred in the working medical parlance.fon·ta·nelle (fon'tă-nel') [TA] One of several membranous intervals at the margins of the cranial bones in the infant. Synonym(s): fonticulus [TA] . [Fr. dim. of fontaine, fountain, spring]fontanel, fontanelle (fŏn″tă-nĕl′) [Fr. fontanelle, little fountain] FONTANELS OF INFANT SKULLAny of the tough, fibrous membranes lying between the bones of the cranial vault of a fetus or infant. Fontanels, colloquially known as soft spots, allow an infant's skull to be compressed during passage through the birth canal. The fontanels ossify generally by age two. See: illustrationanterior fontanelThe diamond-shaped junction of the coronal, frontal, and sagittal sutures; it becomes ossified within 18 to 24 months. posterior fontanelThe triangular fontanel at the junction of the sagittal and lambdoid sutures; ossified generally by age one. fontanelle a gap in the skull bone where the brain and its membranes are covered only by skin. Young human infants possess an anterior fontanelle between frontal and parietal bones on top of the head, and a posterior fontanelle between occipital and parietal bones at the back of the head.FontanelleOne of several "soft spots" on the skull where the developing bones of the skull have yet to fuse.Mentioned in: Hydrocephalus, Subdural Hematomafontanelle Related to fontanelle: sunken fontanelleSynonyms for fontanellenoun any membranous gap between the bones of the cranium in an infant or fetusSynonymsRelated Words- child's body
