Final answer:
Dorsiflexion and inversion are movements of the foot at the ankle joint. Dorsiflexion involves lifting the front of the foot, while inversion involves turning the foot inward towards the midline. These movements help stabilize the foot during activities like walking and running on uneven surfaces.
Step-by-step explanation:
Dorsiflexion and inversion are movements of the foot that occur at the ankle joint. Dorsiflexion is the lifting of the front of the foot towards the anterior leg, while inversion is the turning of the foot to angle the bottom of the foot toward the midline. These movements are important for stabilizing the foot during walking or running on uneven surfaces and during sports that require quick changes in direction.
