Yes. The concept is used in biology for any bilaterally symmetrical organism (e.g., fish, insects). It is also a geometric term applicable to any 3D shape where such a plane of symmetry exists.
The 'midline' is the imaginary line formed where the median plane intersects the body's surface. The 'median plane' is the entire two-dimensional flat surface that extends through the body along that line.
It is essential vocabulary for anatomists, surgeons, radiologists, physiotherapists, biomechanists, zoologists, and artists studying figure drawing. It is a foundational concept in medical and biological sciences.
