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

How many bones are there in all four limbs?
There are a total of 120 bones in all four limbs (30 bones in each arm and 30 bones in each leg).
How many bones does a seal has?
Seals have around 34-36 bones in their fore-flippers (front limbs) and about 26-30 bones in their hind-flippers (back limbs), totaling to approximately 60-66 bones in their skeleton.
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.
What is the similar features that originated in a shared ancestor?
Homologous structures are features that originated in a shared ancestor, such as the bones in the limbs of vertebrates. These features may have different functions in modern organisms but have similar underlying structures due to their common ancestry.
What bones do chickens have that you have?
Chickens and humans have similar bones, such as a skull, backbone, ribs, and limbs. However, chickens also have additional bones such as a wishbone (furcula) and a keel bone to support their wings and flight muscles.
Do the front limbs of a bat cat and horse show similar structure?
yes because they all have bones
Do the limbs move your bones?
Limbs do move your bones. I know because when i was doing my home work i found out limbs make bones move at the limb.
The bones of the limbs are classified as?
long bones

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.
How many bones are in the human limbs?

What is shapes supports your arms and legs?
Shapes that support your arms and legs are typically found in the form of bones, which provide structure and stability to the limbs. The skeletal system, composed of various bones, allows for movement and weight bearing. Additionally, muscles, tendons, and ligaments work together with bones to enhance mobility and support. Overall, these components create a framework that enables the arms and legs to function effectively.
Where are most long bones found in the body!?
Most long bones are found in the limbs.
