Fontanelle

Index Fontanelle

A fontanelle (or fontanel) (colloquially, soft spot) is an anatomical feature of the infant human skull comprising any of the soft membranous gaps (sutures) between the cranial bones that make up the calvaria of a fetus or an infant. [1]

Achondroplasia is a genetic disorder that results in dwarfism.

Anterior fontanelle

The anterior fontanelle (bregmatic fontanelle, frontal fontanelle) is the largest fontanelle, and is placed at the junction of the sagittal suture, coronal suture, and frontal suture; it is lozenge-shaped, and measures about 4 cm in its antero-posterior and 2.5 cm in its transverse diameter.

Calvaria (skull)

The calvaria or skullcap (feminine Latin noun with plural calvariae; however, many medical texts list the word as calvarium, neuter Latin noun with plural calvaria) is the upper part of the neurocranium and covers the cranial cavity containing the brain.

Cleidocranial dysostosis

Cleidocranial dysostosis (CCD), also called cleidocranial dysplasia, is a birth defect that mostly affects the bones and teeth.

Congenital rubella syndrome

Congenital rubella syndrome (CRS) can occur in a developing fetus of a pregnant woman who has contracted rubella, usually in the first trimester.

Coronal suture

The coronal suture is a dense, fibrous connective tissue joint that separates the frontal and parietal bones of the skull.

Craniosynostosis

Craniosynostosis (from cranio, cranium; + syn, together; + ostosis relating to bone) is a condition in which one or more of the fibrous sutures in an infant (very young) skull prematurely fuses by turning into bone (ossification), thereby changing the growth pattern of the skull.

Dehydration

In physiology, dehydration is a deficit of total body water, with an accompanying disruption of metabolic processes.

Down syndrome

Down syndrome (DS or DNS), also known as trisomy 21, is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21.

Lambda (anatomy)

The occipital angle is rounded and corresponds with the point of meeting of the sagittal and the lambdoid suture—a point which is termed the lambda (after the Greek letter of the same name whose lowercase form resembles the junction formed by the sutures); in the fetus this part of the skull is membranous, and is called the posterior fontanelle.

Lambdoid suture

The lambdoid suture (or lambdoidal suture) is a dense, fibrous connective tissue joint on the posterior aspect of the skull that connects the parietal bones with the occipital bone.
