Thesagittal plane (/ˈsædʒɪtəl/; also known as thelongitudinal plane) is ananatomical plane that divides the body into right and left sections.[1] It is perpendicular to thetransverse andcoronal planes. The plane may be in the center of the body and divide it into two equal parts (mid-sagittal), or away from the midline and divide it into unequal parts (para-sagittal).
The termsagittal derives from theLatin wordsagitta, meaning "arrow". An image of an arrow piercing a body and passing from front (anterior) to back (posterior) on a parabolictrajectory with the upright bow that shot it would be one way to demonstrate the derivation of the term. Another explanation would involve the notching of thesagittal suture posteriorly by thelambdoidal suture —similar to feathers on an arrow. TheOxford English Dictionary indicates thatsagittal in the sense of thesagittal suture along the vertex of the skull pre-dates other anatomical usage.[7]
Sagittal axis oranterior-posterior axis is the axis perpendicular to the coronal plane, i.e., the one formed by the intersection of the sagittal and the transversal planes
Coronal axis,medial-lateral axis, orfrontal axis is the axis perpendicular to the sagittal plane, i.e., the one formed by the intersection of the coronal and the transversal planes.[8]
Extension andflexion are the movements of limbs within the sagittal plane.[9]
