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.

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.

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.

Fontanelle

One of several "soft spots" on the skull where the developing bones of the skull have yet to fuse.

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.
