Final answer:
The 8-letter word for your tibia is shinbone.
Step-by-step explanation:
The 8-letter word for your tibia is shinbone (a). The tibia, also known as the shin bone, is the larger of the two bones in the lower leg. It is the main weight-bearing bone and is located on the medial side of the leg. The correct answer is "a) Shinbone." The tibia is indeed an 8-letter word, commonly known as the shinbone. This vital bone is one of the two long bones in the lower leg, alongside the fibula. The tibia plays a crucial role in supporting body weight and connecting the knee to the ankle. Its durability and strength are essential for maintaining stability and facilitating various activities, such as walking and running. Contrastingly, the other options—b) Femur, c) Radius, and d) Humerus—refer to bones in different parts of the body. The femur is the thigh bone, the radius is a bone in the forearm, and the humerus is the upper arm bone. Each bone serves distinct functions in the skeletal system, contributing to the body's overall structure and mobility.
