BCP 201 GD: Bones 5 A-D (Second Timers)

The strongest and longest bone in your body is the femur. Its angled head is filled with compact bone.

The two bones of your forearm arm are the ulna and radius. The two bones of your calf are your tibia and fibula. The bone of your upper arm is the humerus. Where the femur meets the calf’s tibia bone, it widens greatly. It makes a “fat-2 bottom seat.” This is to increase the surface area and strengthen the knee joint.

The wide bone of your pelvis that some of your femur muscles attach to is the:

Bone fibers are organized in specific directions to make the bones stronger. Bone trabeculae are also to make the bone stronger. The trabeculae are also a major site for red blood cell production.

Trabeculae are oriented in directions to strengthen your bones to handle stresses better. “Trab” comes from the Greek word which means ‘beam” or “timber”.

The skull has spongy trabecular bone sandwiched between compact bone. It also has sutures where the skull plates join together. (Research if you need to.)

Plane wings have “ribs” that have different bracing designs built into them. These “ribs“ are nearly always solid plates of steel.
