National Physical Therapy Examination (NPTE) Practice Exam

When assessing the structure of the second cuneiform, what is it most likely to articulate with?

1. The calcaneus

2. The cuboid

3. The navicular

4. The talus

The correct answer is: The navicular

The second cuneiform primarily articulates with the navicular bone. This is an important aspect of foot anatomy, as the cuneiforms play a crucial role in the structure and function of the midfoot. The first cuneiform, the second cuneiform, and the third cuneiform bones are situated in a row and are closely related to the navicular bone, which sits proximally. The articulation between the second cuneiform and the navicular facilitates the distribution of weight and movement during activities such as walking and running, allowing for proper biomechanical function of the foot. Understanding this relationship is critical for a physical therapist when assessing foot mechanics, especially in cases involving midfoot injuries or deformities. Other bones mentioned, like the calcaneus, cuboid, and talus, also have important roles in foot anatomy but do not directly articulate with the second cuneiform. The calcaneus is the heel bone, the cuboid is more laterally positioned in the foot, and the talus sits above the calcaneus, forming the subtalar joint. Their articulations involve different bones and are situated at different anatomical locations.
