The hollow cylinder part of the long bone is called the medullary cavity. It is filled with bone marrow and helps reduce the weight of the bone while providing support and flexibility.
An emu's bones are solid and adapted for long periods of running and walking. A seagull's bones are light and hollow so they can fly easily.
It is the space where you will find bone marrow, which is where Red Blood Cells and White Blood Cells are formed
There are five different types of bone in a human body. If you are talking about long bones, such as your femur or tibia (aka the long bones in your arms and legs), then in the middle of them are bone marrow. Yellow marrow for adults and red marrow for children.
The hollow part of bones are mostly filled with Red Marrow
The long bones are almost exactly the same. Chickens, like most birds, generally have a lighter bone structure with a slightly larger hollow space, but other than that they are about the same.
The hollow interior part of a long bone contains bone marrow.
The shaft of the bone, between the epiphyses, is called the diaphysis. It has a hollow central medullary cavity containing marrow.The shaft of long bones is called DIAPHYSIS
Because they move bone (teeth) through bone.
The medical term for the end region of a long bone is the epiphysis. It is responsible for bone growth and connects to the shaft of the bone through the metaphysis.
The primary blood supply to the diaphysis of a long bone is through the nutrient artery, which enters the bone through the nutrient foramen. This artery provides blood to the medullary cavity and inner portions of the bone.
Technically speaking, it is hallow because there needs to be room for what's stored inside. The stuff inside is called marrow, which makes blood and has blood vessels that are in it so blood can flow throughout the body, and without marrow, we'd all be dead. :)
