What does craniometry specifically measure?

Craniometry specifically focuses on the measurements of the bones of the skull. This branch of anthropometry examines various aspects of cranial dimensions, which can reveal insights into human development, evolutionary biology, and can assist in forensic anthropology to identify individuals based on cranial features.

When considering the other options, dimensions of the skeletal system encompasses various bones throughout the body, including limbs and the spine, not just the skull. Body composition pertains to the proportion of fat, muscle, and bone within the body, which is unrelated to craniometry. Range of motion refers to the extent of movement in a joint or series of joints, which also does not involve the specific measurement of skull bones. Therefore, the focus of craniometry on skull measurements distinctly sets it apart from these other topics.
