How does one sign up for donating bone marrow?
You can join the Bone Marrow Registry to donate bone marrow online at the Bone Marrow National Registry. You must be between the ages of 18 and 44. Doctors choose registry members for donations 90% of the time, so it is a good idea to register so you can help someone in their time of need.
Does the calcaneous articulate with the distal end of the tibia?
The distal tibia articulates with the talus. The proximal tibia articulates with the femur.
What are the three bones that articulate with the femur?
The proximal end of the femur articulates with the acetabulum, which is the socket joint of the pelvis. The acetabulum is formed by the fusion of the three bones which make up the pelvis, the ischium, the ilium and the pubis.
The distal end of the femur articulates with the patellae (knee caps) and the tibia.
What system does the skeletal system work with to help move your body?
Cartilage, ligaments, and Muscles!
How does the respiratory system helps the skeletal system?
the bones protect the lungs that breath
not only that, the movement of the bones help the amount of air that can be taken in or let out
during inspiration (i.e; taking air in), the ribcage moves upwards and outwards (because of the contraction of external intercostal muscles and relaxation of internal intercostal muscles), this causes the sternum (chest bone) to move up and away from the ribcage. as a result, the 'dorsoventral' diameter of the thorax (lung cavity) increases. more air can now be taken in.
during expiration, the action is entirely opposite to this
What would happen if your bones were weak?
Well, think of your muscles like your "businesses". Each muscle is a business you have been born with to make "money". So if a business grows weak, in muscles, a weak business can only get worse or get better. But once a muscle goes out of business, that's the end of it. The muscle fibers lost, can never be gained back...But! If you still have muscle, you can strengthen it like a struggling business, by working harder, working out, using them more than usual. If you leave them weak, they will over time, and quite quickly, shrink (atrophy), and the deterioration of muscles is very bad. You must keep what you have and make it stronger, because once it's gone, it's gone. :) Hope that helped.
Spiral fractures are described as crossing a bone at an oblique angle, creating a spiral pattern. This break usually occurs in the long bones of the body such as the upper arm bone (humerus) or the thigh bone
Is the lungs in the front or the back of the ribs?
The lungs are inside your body so it isn't really in the front or back. It is in the chest area or upper body.
Does the rib cage protect the kidneys and the lungs?
Yes. The inferior edge of the liver can be palpated (felt) just inside the lowest portion of the rib cage.
Are babies bones softer than adults?
They don't have much hair on their skin. And they don't have many scars, dry spots, calluses, blisters, or other marks that would make their skin rough or bumpy. Many parents apply moisturizer to their babies' skin to help with diaper rash.
What systems does the skull belong to?
Cranium is apart of the skeletal system. it is the bone that protects the brain.
What is name for the movement of a bone or limb toward the body?
Adduction brings the body part toward the midline of the body. Example, raise arms above your head and clasp your hands together
Abduction brings the body part away from the midline of the body. Example, raise your arms from the waist up to shoulder height keeping the hands level with the shoulders
Where in the body is a bone called the patella?
The patella is also known as the knee cap, right above the tibia and fibula, and right below the femur.
Which bone articulates with the distal tibia and fibula?
The bone thst articulates with the tibia and fibula is the Talus bone.
What joint allows one bone to rotate around the another?
Ball and socket joint as found in the hip and shoulder.
After the patient is anesthetized, the surgeon makes a cut (incision) in the mucous tissue that covers the part of the septum that is made of cartilage. The tissue is lifted. Cartilage is cut away as needed.
What does Tendons attach to the bones.?
Tendons connects the muscle to the bones. They also connect to your biceps and triceps.
What are the flexible parts that join bones?
A joint is the location at which two or more bones make contact. They are constructed to allow movement and provide mechanical support, and are classified structurally and functionally.1

What is the lightest bone in your body?
It contains calcium which is a substance that does not weight. Therefore it makes bones be strong and hard. If you took the calcium, the bones would be flexible and not hard at all.
Can you break every bone in your body and live?
Yes even though there's a chance one could be parilyzed.
