Final answer:
The term 'femoral' correctly describes anything that pertains to the thigh bone, which is scientifically referred to as the femur.
Step-by-step explanation:
The correct spelling of the term that means "pertaining to the thigh bone" is femoral. The femur is the longest and strongest bone in the body, constituting roughly a quarter of a person's total height. The proximal end of the femur, known as the head, articulates with the acetabulum of the hip bone to form the hip joint. The femur's distal end has three articulating surfaces: the medial and lateral condyles, and the patellar surface.
