Planes of the body

Plane

An imaginary line along which any two points can be connected and cut in a straight line.

Median plane

A plane that divides the body longitudinally into left and right equal halves.

Sagittal plane

A plane that divides the body into two unequal right and left halves, parallel to the median plane.

Dorsal plane

A plane that runs at a right angle to the median and transverse planes and divides the body into dorsal and ventral halves.

Transverse plane

A plane that is perpendicular to the long axis of the body. It is at a right angle to both dorsal and median planes. It cuts the body into cranial and caudal parts
