How Do You Spell SPINA MENTALIS?

Pronunciation: [spˈiːnə mɛntˈɑːliz] (IPA)

Spina mentalis is a medical term that refers to a bony ridge on the inside of the mandible. The spelling of this word can be explained using IPA phonetic transcription. "Spina" is pronounced as /ˈspiː.nə/ with the stress on the first syllable. "Mentalis" is pronounced as /menˈteɪl.ɪs/ with the primary stress on the second syllable. The "s" sound in "spina" is voiced, while the "s" sound in "mentalis" is voiceless. This subtle difference in pronunciation is reflected in the spelling of the two words.

SPINA MENTALIS Meaning and Definition

1. Spina mentalis is a Latin term commonly used in the field of anthropology and physical anthropology to describe a specific morphological feature found in humans, particularly within the mandible or lower jawbone. The term "spina mentalis" translates to "mental spine" in English.

   The spina mentalis is an anatomical structure that refers to a prominent ridge or bony protuberance located on the interior surface of the mandible. It is typically found in the midline, running vertically along the lower jawbone. This feature is specifically formed due to the attachment of the genioglossus muscle, which is responsible for controlling the movement and position of the tongue.

   The prominence of the spina mentalis can vary among individuals, with some having a distinct, well-developed ridge, while others may exhibit a less pronounced or absent spina mentalis. The size and shape of this structure can also differ based on various factors such as age, sex, and genetic traits.

   The examination and study of the spina mentalis are of considerable interest to anthropologists, as it can provide valuable insights into the morphological variations of human populations and aid in the understanding of evolutionary processes. Additionally, the presence or absence of the spina mentalis can also have implications in dental and orthodontic treatments, as well as forensic identification and analysis.

2. Mental spine, genial tubercle; a slight projection, sometimes two, in the middle line of the posterior surface of the body of the mandible, giving attachment to the geniohyoid muscle (above) and the geniohyoglossus (below).
