Chapter 8, Problem 17
The tarsal bone that transfers and distributes weight to the heel or toes is the:
(a) Cuneiform
(b) Calcaneus
(c) Talus
(d) Navicular
Verified step by step guidance1
Step 1: Understand the function of the tarsal bones in the foot. The tarsal bones are a group of seven bones in the foot that help support weight and allow movement. Each has a specific role in weight transfer and distribution.
Step 2: Identify the role of the calcaneus. The calcaneus, also known as the heel bone, is the largest tarsal bone and primarily responsible for bearing the body's weight when standing and during heel strike in walking.
Step 3: Consider the talus bone. The talus sits above the calcaneus and forms the lower part of the ankle joint, transferring weight from the tibia to the foot but not directly distributing weight to the toes or heel.
Step 4: Review the cuneiform and navicular bones. These bones are located more distally in the foot and mainly serve as connection points for the metatarsals and other tarsals, playing a lesser role in direct weight transfer to the heel or toes.
Step 5: Conclude that the tarsal bone responsible for transferring and distributing weight to the heel or toes is the calcaneus, as it directly supports the heel and is the main weight-bearing bone in the rearfoot.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Tarsal Bones Anatomy
Tarsal bones are a group of seven bones in the foot that form the ankle and heel region. They provide structural support and facilitate movement by connecting the foot to the leg. Understanding their location and function is essential to identify which bone plays a key role in weight transfer.

Function of the Talus
The talus is a tarsal bone that sits between the tibia and calcaneus, acting as a critical link in transferring body weight from the leg to the foot. It distributes weight to the heel and toes, enabling balance and movement during walking and standing.

Role of the Calcaneus
The calcaneus, or heel bone, is the largest tarsal bone and primarily supports the body's weight when standing. It serves as the main point of contact with the ground and provides leverage for muscles during walking, but it mainly receives weight rather than distributing it forward.
