mesocephalic

mesocephalic

A doctor measures a patient's mesocephalic head shape.

Definition
  1. Adjective:
    • Having a medium-sized head: "mesocephalic" describes a skull or head shape that is intermediate in width relative to its length, typically characterized by a cephalic index between 75 and 80. This term is used in anthropology and medicine to classify human skull types.
Usage Examples
  • Adjective:
    • The skull discovered at the archaeological site was identified as mesocephalic, falling within the average range for that population. (The skull's width-to-length ratio was intermediate.)
    • Many modern human populations are considered mesocephalic, meaning their head shape is neither especially long nor especially broad. (Describing a common head shape classification.)
Advanced Usage

  • "mesocephalic index": a numerical measure indicating a medium head shape, calculated as (head width / head length) × 100.

    • A mesocephalic index is typically between 75 and 80, distinguishing it from dolichocephalic (long-headed) and brachycephalic (broad-headed) types. (A specific range for classification.)

  • "mesocephalic skull": a skull with a moderate cranial index.

    • The anthropologist noted that the mesocephalic skull was common in the region's prehistoric inhabitants. (A skull with intermediate proportions.)
Variants and Related Words

  • Mesocephaly (noun): the condition of having a medium-sized head.

    • Mesocephaly is often considered the norm in many human populations. (The state of being mesocephalic.)

  • Mesocephalic (noun): a person with a medium-sized head.

    • The study compared the cranial measurements of dolichocephalics and mesocephalics. (A person classified as having an intermediate head shape.)
Synonyms
  • Medium-headed: having a head of average proportions.
  • Normocephalic: having a normal-sized head (often used in medical contexts, but broader than mesocephalic).
Antonyms
  • Dolichocephalic: having a long, narrow head (cephalic index less than 75).
  • Brachycephalic: having a short, broad head (cephalic index greater than 80).
Related Terms
  • Cephalic index: a measurement used to classify head shapes, calculated as the ratio of head width to head length.
    • The cephalic index is key to determining whether a skull is dolichocephalic, mesocephalic, or brachycephalic. (The metric underlying the classification.)
Etymology
  • Mesocephalic comes from Greek (middle) + (head), literally meaning "middle-headed."
