Final answer:
In closed-chain pronation of the ankle, calcaneal eversion and talar abduction are the movements that occur. Calcaneal inversion and talar adduction are associated with supination and are incorrect in this context.
Step-by-step explanation:
The question "With closed-chain pronation of the ankle, which of the following are true?" involves an understanding of anatomical movements related to the ankle and foot. Here, the talar and calcaneal movements in question refer to the movements facilitated by the subtalar joint and other intertarsal joints, and not the talocrural (ankle) joint, which only allows for dorsiflexion or plantar flexion. Closed-chain pronation typically includes dorsiflexion, eversion, and abduction; therefore, the correct answers would be:
- B) Calcaneal eversion
- C) Talar abduction
Calcaneal inversion and talar adduction would be associated with supination, not pronation.
