Hip joint problems can also cause pain that occurs in other areas, not just the groin. The groin is the most common location for hip joint pain, but pain can also occur in the back of the hip (the buttocks), the thigh, and even in the knee.
Midsagittal plane. Definition. noun. (anatomy) A plane passing vertically through the midline, dividing the body into left and right halves of equal proportion (i.e. in the case of bilateral symmetry). Supplement. In human body, a median plane is a sagittal plane passing through the midline structures such as the navel and spine.
The planes resemble imaginary glass panels that pass through the midline of your body. The frontal plane divides your body in half front to back. The sagittal plan divides your body in half side to side. The transverse plane divides your body in half top to bottom. An exercise that follows the imaginary glass panel occurs within that particular plane.
