What substance is housed in the medullary cavity yet absent in the trabeculae?
The medullary cavity of bones typically contains bone marrow, which is responsible for producing blood cells. Trabeculae, on the other hand, are the structural beams within cancellous or spongy bone that provide support and strength. Bone marrow is not present in the trabeculae.
What membrane lines lines the medullary cavity?
The endosteum lines the medullary cavity.
What is another name for the medullary cavity of the bone?
Another name for the medullary cavity of the bone is the marrow cavity.
Does bone have a medullary cavity?
true
Which of the following explanations best describes how the medullary cavity of a long bone forms?
The medullary cavity of a long bone forms during development through a process called endochondral ossification. This process involves the replacement of cartilage with bone tissue, with osteoclasts breaking down the center of the bone shaft to create the cavity where bone marrow will eventually reside.
How does the marrow in the medullary cavity compare to the marrow in the spongy bone?
The marrow in the medullary cavity is primarily composed of yellow marrow, which stores fat, while the marrow in the spongy bone is red marrow where blood cells are produced. Yellow marrow is found in long bones, whereas spongy bones contain red marrow in their trabeculae.
What is the function of the medullary cavity?
The medullary cavity is the central cavity of bone shafts. This is where red and yellow bone marrow are stored. The medullary cavity is also involved in the formation of red and white blood cells.
Is fat stored in the medullary cavity?
yes
Does human clavicle contains medullary cavity?
No
What structure lines the medullary cavity?
endosteum
What Cells that holow out the medullary cavity?
diaphysis
How can we use the diameter to calculate the medullary index?
The medullary index is calculated by comparing the diameter of the medullary cavity to the diameter of the entire bone. To find the medullary index, you divide the diameter of the medullary cavity by the total diameter of the bone and then multiply the result by 100 to express it as a percentage. This index helps assess the relative size of the medullary cavity in relation to the overall bone structure, which can be useful in fields like anthropology and forensic science.
