No, they're made of hyaline cartilage
Spongy bone is not filled with cartilage. Spongy bone is composed of trabeculae, which are interconnected plates and rods. Cartilage is a different type of connective tissue that can be found in joints and in the growth plates of bones.
Spongy bone is made of trabeculae, which are a network of bony spines and plates. It contains red bone marrow, responsible for producing blood cells, and has a higher surface area for metabolic activities compared to compact bone. Spongy bone is found at the ends of long bones and inside flat bones.
The epiphyseal plate is made of cartilage that forms at the ends of the long bones of the body. It is seen in infants and children. Once the child reaches adulthood, the plate has solidified into bone.
Spongy bones contain what is called cancellous tissue, which is bone with a spongy or honeycomb appearance. This is where new blood cells are made.This cancellous bone framework is called the erythropoietic framework because it makes new blood cells.
Bone marrow is the substance that is found at the core of bones, and is either made of fat or red blood cells depending on the type of bone in question. For spongy bone, the marrow is made of red blood cells.
Spongy bone looks something like a sloppily made honeycomb covered with an outer layer of solid compact bone. The spaces in the spongy bone are filled with red bone marrow and blood vessels.
Spongy bone looks like what a sponge looks like. It has many openings and a thin covering of hard bone over it.
Trabeculae in spongy bone provide structural support and help distribute forces within the bone. They also contain red bone marrow, where blood cells are produced.
Spongy bone produces red blood cells, white blood cells, and platelets through a process called hematopoiesis. It also helps to store and release minerals, such as calcium and phosphorus, to maintain bone health and overall body function.
spongy bone my teacher say...
epiphyseal plate, it is made up of cartilage that expands and is turned into bone with elongates the bone.
The layer of bone tissue you are referring to is spongy bone. It is made up of trabeculae, which are spiky structures that create open spaces filled with bone marrow. Spongy bone is important for providing structural support and flexibility to bones.
