Leg bone in human body is

Leg bone in the human body is [C] solid. The leg bones, including the femur, tibia, and fibula, are composed of dense cortical bone tissue, which is solid and compact. This solid structure provides strength, support, and protection to the lower limbs, allowing them to withstand the forces exerted during weight-bearing activities like walking, running, and jumping.

Unlike some bones, such as the long bones of birds, which can be hollow to reduce weight, human leg bones are solid to better withstand the mechanical stresses and strains encountered during locomotion. Additionally, the porous nature of bone tissue, known as trabecular or cancellous bone, is present within the interior of the bone to provide flexibility and absorb shock.
Overall, the solid composition of leg bones ensures their durability and functionality, enabling efficient movement and weight-bearing while minimizing the risk of fractures and injuries.
