the structure of the ankle

1. the top of the foot is called the surface.
2. the bottom aspect of the foot is called the surface.
3. the medial aspect of the foot is the of the ankle.
4. the lateral aspect of the foot is the fibula of the ankle.
5. the ankle joint acts like a joint.
6. the bones of the ankle make up a and tenon structure which is one of the most stable structures used (often in carpentry and buildings).
7. the bones are lines with articular . this allows the bones to move smoothly against one another. it is about ¼ inch thick and is soft enough to allow for shock - absorption but strong enough to last a lifetime.
8. bones and joints of the ankle – label them by placing the letter on the appropriate bone:

a. talus
b. calcaneous
c. tibia
d. fibula
lateral view
talus works like a inside the socket to allow your foot to
a. move up – which is called dorsiflexion
b. move down – which is called plantar - flexion

Explanation:

1. The top of the foot is called the dorsal surface based on anatomical naming.
2. The bottom aspect of the foot is the plantar surface, a standard anatomical term.
3. The medial aspect of the foot is the inside of the ankle, referring to the side closer to the other foot.
4. The lateral aspect of the foot is the outside of the ankle, the side away from the other foot.
5. The ankle joint acts like a hinge joint as it mainly allows movement in one - plane (dorsiflexion and plantarflexion).
6. The bones of the ankle make up a Mortise and Tenon structure, similar to stable carpentry and building structures.
7. The bones are lined with articular cartilage which allows smooth movement and shock - absorption.
8. In the lateral view of the ankle, the appropriate labels for the bones are as follows based on their anatomical positions. The talus (A) is the bone that articulates with the tibia and fibula and allows foot movement, the calcaneous (B) is the heel bone, the tibia (C) is the larger of the two lower - leg bones on the medial side, and the fibula (D) is the smaller lower - leg bone on the lateral side.

Answer:

1. Dorsal
2. Plantar
3. Inside
4. Outside
5. Hinge
6. Mortise
7. Cartilage
8. A. Talus, B. Calcaneus, C. Tibia, D. Fibula
