My 13 year old son has alump on his lower rib cage or the cartilage what could it be?
Sounds like costochondritis or Tietze's syndrome, which involves swelling of the cartilage in the lower rib cage. The lump is most likely due to inflammation and possibly the ribs slipping over one another, which can cause a clicking sensation. This problem can be brought on by some sort of trauma and often resolves on its own, or it can become a chronic problem that is related to other inflammatory conditions. Have your son checked by a rheumatologist, if possible, to rule out juvenile forms of arthritis.

What do you have that at birth you have 300 and at adulthood you have 206?
At birth, humans have approximately 300 bones, many of which are made up of cartilage and later fuse together as the body grows. By adulthood, the number of bones typically reduces to 206 due to this fusion process. This transformation allows for greater strength and stability in the skeletal structure as one matures.
What happened to your leg when it was tapped below the knee?
If your leg is tapped below the knee, this often results in your leg flinching. This is caused by a reflex in the leg, and it shouldn't be painful, but some people say it tickles.
What two things do your bones do for your body?
The bones support the soft or fleshy parts of the limbs, and form a framework that gives them shape. They form, in some cases, levers upon which the muscles act, and give origin to the various motions of the leg and foot. When dead bone is examined it is a hard-looking, whitish-yellow, tough substance. It is light in weight when compared with its strength. In its living state it has a pinky colour, due to the blood circulating through its minute channels. The exterior of the bone is cased - except when covered by cartilage - with a thin, firm membrane. If this membrane is injured, local death takes place in that part of the bone, because of its being deprived of its nutrition. This membrane also affords means whereby the muscles, tendons, and ligaments may be attached to the bone. It forms a smooth surface to the bone, and so reduces friction; so that its use is threefold : (1) to act as a medium to convey nutriment to the bone it covers; (2) to lessen friction; and (3) to provide a means of attachment for muscles, etc. If a piece of bone be examined under a microscope it is seen to be filled with an infinite number of minute canals containing blood-vessels, and it is through these little tunnels that the bone is built up and nourished.
The bones at the commencement of their formation are composed of cartilage, or gristle, and are gradually made into bone by the earthy salts being deposited through the blood-vessels, thereby imparting rigidity to the cartilage. In childhood bones are made up of parts which do not unite until maturity is reached, so that it is easy to bend or misshape them. I'm 11 and in sixth grade and I know this.
Where is the fema bone located on the body?
The femur bone, commonly referred to as the thigh bone, is located in the upper leg of the body. It extends from the hip joint to the knee joint, connecting the pelvis to the lower leg bones. The femur is the longest and strongest bone in the human body, playing a crucial role in supporting weight and enabling movement.
