The bones of the lower limbs articulate through various joints, primarily at the hip, knee, and ankle. The femur connects to the pelvis at the hip joint, forming a ball-and-socket joint that allows for a wide range of motion. The femur also articulates with the tibia and patella at the knee joint, which is a hinge joint enabling flexion and extension. Finally, the tibia and fibula connect at the ankle joint, where the tibia articulates with the talus of the foot, allowing for movement and stability.
What else can I help you with?
Is upper limb contains more bones than lower limbs?
No, the upper limbs contain fewer bones than the lower limbs. Each upper limb has 30 bones, including the humerus, radius, and ulna, while each lower limb has 31 bones, including the femur, tibia, and fibula. Overall, the lower limbs have a greater number of bones due to the presence of additional structures like the patella and the bones of the foot.
Which bones articulate with the distal radius?
The lower extremity of the radius actually has two bones which it articulates with. The carpal and the ulna.
Why are the bones of the lower limbs larger and heavier than upper limbs?
The bones of the lower limbs are larger and heavier than the bones of the upper limbs because they must support the body's weight and provide stability during activities like walking, running, and jumping. The lower limbs also have larger muscle groups attached to them, which contribute to their increased size and strength compared to the upper limbs.

The sets of bones that support the limbs of vertebrates are called?
