What does the term "tarsal" specifically refer to?

The term "tarsal" specifically refers to the structures associated with the ankle. In human anatomy, the tarsal bones are a group of seven bones located in the foot, just above the metatarsals, which connect to the toes. These include the talus, calcaneus, navicular, cuboid, and the three cuneiform bones. The tarsal region plays a crucial role in supporting body weight and facilitating movement, particularly in walking and running.

In contrast, the other terms in the choices refer to different anatomical regions. The knee is associated with the femur and tibia, the foot includes all structures from the tarsals to the toes but is broader than just the tarsals, and the thigh pertains to the femur and structures in the upper leg. This differentiation is essential for understanding the various segments of the lower limb in anatomy.
