Which seven bones make up the ankle (tarsus)?

Verified step by step guidance

Step 1: Understand that the ankle, also known as the tarsus, is composed of seven bones that form the connection between the leg and the foot.

Step 2: Identify that these seven bones are collectively called the tarsal bones, which are arranged in two rows: the proximal row and the distal row.

Step 3: List the bones in the proximal row, which includes the talus and the calcaneus. The talus articulates with the tibia and fibula to form the ankle joint, while the calcaneus is the heel bone.

Step 4: List the bones in the distal row, which includes the navicular, the three cuneiform bones (medial, intermediate, and lateral), and the cuboid bone.

Step 5: Summarize that the seven tarsal bones making up the ankle (tarsus) are: talus, calcaneus, navicular, medial cuneiform, intermediate cuneiform, lateral cuneiform, and cuboid.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Ankle (Tarsus) Anatomy

The ankle, or tarsus, is a complex joint composed of seven bones that connect the leg to the foot. Understanding its anatomy is essential for identifying these bones and their roles in movement and support.

Names of the Seven Tarsal Bones

The seven tarsal bones include the talus, calcaneus, navicular, cuboid, and three cuneiform bones (medial, intermediate, and lateral). Each bone has a specific location and function within the ankle structure.

Function and Importance of Tarsal Bones

Tarsal bones provide stability, support body weight, and enable foot movements such as walking and running. Recognizing their function helps in understanding injuries and conditions related to the ankle.
