Explanation: Medial and lateral menisci. The condyles of the femur and the tibia are partially separated by two interposing fibrocartilaginous discs, or menisci, the medial and lateral menisci. Each meniscus is C-shaped, and a transverse ligament joins their anterior margins.
Explanation: Dorsiflexion and plantarflexion. The talocrural (ankle) joint is capable of two movements. Dorsiflexion is the drawing up of the dorsum of the foot that allows the heel to strike the ground first. Plantarflexion is the opposite movement that points the foot downward. The intertarsal joint is capable of inversion and eversion of the ankle.
Explanation: Soleus. The iliacus and psoas muscles (together referred to as the iliopsoas muscle), the rectus femoris muscle, and the sartorius muscle all contribute to hip flexion. The soleus muscle is responsible for plantarflexion of the foot.
