How Do You Spell METOPISM?

Pronunciation: [mˈɛtə͡ʊpˌɪzəm] (IPA)

Metopism is a term that refers to the condition where the frontal suture (the line running between the two halves of the forehead) does not fuse together during infancy. This results in an open space between the two sides of the skull. The word is pronounced as /mɛˈtɒpɪz(ə)m/ with the stress on the second syllable. It is spelled with an "o" before the "p" and an "i" before the "s," which may seem counterintuitive, but is derived from its Greek roots.

METOPISM Meaning and Definition

1. Metopism is a term used in anatomy to describe a specific condition in which the frontal suture, a fibrous joint that usually separates the two halves of the skull, remains unclosed in adulthood. This suture is typically present in newborns, running along the midline of the forehead, but it normally fuses and disappears as an individual grows older. However, in cases of metopism, the frontal suture remains patent and persists throughout the person's life.

   The persistence of the frontal suture can result in a unique appearance known as "metopic ridge" or "metopic suture." This ridge appears as a raised line running vertically down the middle of the forehead, dividing it into two distinct sides. The presence of a metopic ridge is often evident during medical examinations or when examining skull X-rays.

   Metopism is generally considered a variation within the normal range of human anatomy and development. It is not considered a pathological condition, but rather a natural anatomical variation that can occur in a small percentage of the population. The frequency of metopism varies among different populations and ethnic groups.

   While metopism does not typically cause any health issues or functional problems, it can be associated with certain genetic or developmental conditions. In rare cases, it may be linked to craniosynostosis, a condition in which the sutures of the skull prematurely fuse, affecting skull growth and shape. However, it is important to note that metopism by itself is not indicative of craniosynostosis or any other medical condition.

Etymology of METOPISM

The word "metopism" is derived from the combination of two Greek words: "metopos" (μετώπος) meaning "forehead" and "ismos" (ισμός) which denotes a condition or state. Thus, "metopism" refers to a condition or state related to the forehead.
