A sagittal plane of the human body is an imaginary plane that travels vertically from the top to the bottom of the body, dividing it into left and right portions.
[edit] VariationsExamples include:
[edit] TerminologyThe term is derived from the Latin word Sagitta, 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 lamboidal suture—similar to feathers on an arrow. Sagittal axis: Sagittal axis is the axis perpendicular to the sagittal plane, i.e. the sagittal axis is formed by the intersection of the coronal and the transversal planes. Abduction and adduction are terms for movements of limbs relative to the coronal plane. Coronal (or frontal) axis: Coronal axis is the axis perpendicular to the coronal plane, i.e. the coronal axis is formed by the intersection of the sagittal and the transversal planes. Extension and flexion is the movement of limbs relative to the sagittal plane. [edit] See also[edit] References
