fontanel

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.

fontanelle

(fŏn′tə-nĕl′)
n.
Any of the soft membranous gaps between the incompletely formed cranial bones of a fetus or an infant. Also called soft spot.

fontanel

[fon′tənel′]
Etymology: Fr, fontaine, fountain
a space covered by tough membranes between the bones of an infant's cranium. The anterior fontanel, roughly diamond-shaped, usually closes between the ages of 12 and 18 months. The posterior fontanel, triangular in shape, closes about 2 to 3 months after birth. Increase in intracranial pressure may cause a fontanel to become tense or bulge, as evidenced in infection such as meningitis. A fontanel may be soft and depressed as a result of dehydration. Also spelled fontanelle, fonticulus.

FONTANELS OF INFANT SKULL
Any 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: illustration

anterior fontanel

The diamond-shaped junction of the coronal, frontal, and sagittal sutures; it becomes ossified within 18 to 24 months.

posterior fontanel

The triangular fontanel at the junction of the sagittal and lambdoid sutures; ossified generally by age one.

Fontanel

One of the membranous intervals between the uncompleted angles of the parietal and neighboring bones of a fetal or young skull; so called because it exhibits a rhythmical pulsation.

fontanel (fôn·t·nel),

n the membrane-covered area between an infant's cranial bones before they close. The anterior fontanel usually closes at 14 months of age while the posterior fontanel closes 2 months after birth. There can be a significant bulge in the fontanel during some infections, such as meningitis. Also called
fontanelle or
fonticulus.

fontanelle, fontanel

a soft spot; skin and membrane-covered spaces remaining at the junction of the sutures, especially between the frontal and parietal bones in the incompletely covered skull of the fetus or neonate. This fontanelle usually closes after birth but in hydrocephalus and in some miniature breeds of dogs, particularly Chihuahuas, it may remain open. Called also fonticulus, molera.
