In what ways are the shapes and arrangements of the bones in the upper and lower limbs similar?

At one time we evolved from animals that used 4 legs for moving. And this is the reason that the bones in the upper and lower limbs are so similar. We have adapted the hand so that is more functional than the foot.

∙ 12y ago- The Pelvic Girdle is a complete circle while the Pectoral Girdle is not
- The Pelvic Girdle does not support the weight of the body, rather it is the attachment site for many muscles that move the upper limbs. (the collar bone's main function is to keep the shoulder joint away from the midline of the body allowing greater it greater mobility). In contrast, the pelvic girdle receives the weight of the upper body from the axial skeleton, (the spine) and supports it.
- They both employ hinge joints in the middle, "the ginglymus of the upper extremities and the tibiofemoral joints of the lower extremities"
- They both have an interosseous membrane separating them. (This keeps them at a fixed distance from each other. It only allows slight movements between them.)
- The femur has a landmark called the "fovea" through which a tiny ligament connects it to the acetabulum. The humerous does not have this.
- the most commonly fractured bone of the upper extremities is the upper arm, (humerous), while the most commonly fractured bone(s) of the lower extremities is the lower leg (tibia and fibula,) (the crural region).
- lower extremity has a large sesamoid bone called the patella, upper extremities do not.
- the distal ends of the ulna, radius, tibia, and fibula, are called, the styloid processes and the lateral and medial malleolus. These landmarks help to stabilize the condyloid joints of the wrists and ankles.
there's probably more, but this is all I can think of.

∙ 16y agoboth the arms and the legs can be bended... the arms are connected to the hands while the legs are connected to the feet... both are the longest parts of the body...

How many bones are there in all four limbs?

Why are the bones of the lower limbs larger and heavier than upper limbs?
Because they have evolved (or were designed, whichever you choose to believe) as to be the primary weight bearing limbs, so they have to be more sturdy to do that job than the upper limbs.
Why would you expect the arm bones of a weight lifter to be thicker and heavier than those of a jogger?
The larger arm muscles of the weight lifter would apply more mechanical stress to the bones of the upper limbs. In response tothat stress, the bones would grow thicker. For similar reasons, we would expect the jogger to have heavier and thicker thigh bones.

What bone is not an axial bone?
Axial bones are those that are found within your head, vertebral (spinal) column, and ribcage. Any other bone is considered part of the appendicular skeleton; these include all bones related to the upper and lower limbs. This includes your clavicle (collarbone), scapula (shoulder blade), and pelvic bones, even though they are part of your torso (and obviously all bones that are further down in the limbs).
