Anatomical terminology []

A sagittal plane [ˈsæ.dʒɪ.tl̩] is an anatomical plane which divides the body into right and left parts. The plane may be in the centre of the body and split it into two halves (mid-sagittal) or away from the midline and split it into unequal parts (para-sagittal).

Most elements of Irish dancing occur in the sagittal plane.

Examples include:

The term sagittal is derived from the Latin word , meaning "arrow". An image of an arrow piercing a body and passing from front (anterior) to back (posterior) on a parabolic trajectory would be one way to demonstrate the derivation of the term. Another explanation would be the notching of the sagittal suture posteriorly by the lambdoidal suture —similar to feathers on an arrow.
